Injection Packers for Crack, Water Stop and Leak Sealing Injections

SealBoss injection packers connect the injection equipment (applicator and injection pump) with the structural substrate to serve as the port of entry – or filler neck – for a large variety of injection resins and chemical grouts into concrete mediums.

Our Packers are made from a various metals including steel, brass, zinc, aluminum / aluminium or plastic. Packers are typically equipped with either a zerk fitting or button head fitting for easy and secure connection to the applicator. The button head type offers the most secure connection in overhead, high pressure and high volume appplications.

Conditions of the jobsite, environment and material determine the type, material, and build of packer, in order to achieve the best injection results. SealBoss provides a very large selection of injection packers to meet all professional needs.

Injection Packers – Installation Types

Based on injection requirements and injection products to be used, we distinguish between borehole packers and surface mount packers, also known as surface ports.

Cylinder shaped, borehole type injection packers are typically used for high pressure injection with polyurethane bases, water stop and leak-seal resins and injection foams.

Borehole style packers work very well in wet and otherwise demanding environments, such as deteriorating concrete substrates.

We further differentiate between mechanical packers with a tighten-down and screw-in mechanism, and hammer-in technique packers.

The seal of the aforementioned packers is achieved by friction between the packer body in the drill hole and the surrounding substrate.

Surface mounted ports are mostly used for structural epoxy injection where a non-destructive injection process – no drill holes allowed procedure – is specified.

Surface mounted packers or surface ports are glued to the surface of the substrate and rely on the bond strength of the adhesive, such as SealBoss 4500 epoxy paste adhesive. Surface port placement is best performed on a dry substrate and can be difficult in wet environments with active water leaks.

for Commercial and Residential Seawalls

Seawalls serve as guardians of our coastlines, protecting against the ocean’s force while shielding properties by bays, rivers, and lakes. Yet, their resilience is tested by the ceaseless tides and natural elements, leading to gradual wear over time.

Regular repair and maintenance are essential to keep seawalls in good working order, ensuring their longevity and continued effectiveness in safeguarding both natural and developed areas against erosion and flooding.

Regular repair and maintenance are essential to keep seawalls in good working order, ensuring their longevity and continued effectiveness in safeguarding both natural and developed areas against erosion and flooding.

SealBoss Seawall Repair Methods Introduction:
Seawall Failures and Effective Seawall Repair Strategies

Over the passage of time, even the sturdiest seawalls can exhibit cracks, becoming susceptible to water penetration. In certain scenarios, the very foundation of the seawall might shift due to the erosion of its supporting substrate. Proactively identifying and rectifying these concerns can stave off escalated damage, ensuring the seawall remains a steadfast defense against water and erosion.

Whether for private residences or commercial establishments, many seawalls are crafted with similar design principles.

Their upkeep and restoration can be effectively managed using hydro-active, hydrophobic polyurethane foams for leak-sealing and water-stopping, as well as two-component or dual-component polyurethane foams for void-filling, elevation, and support of foundations and bulkheads.

When it comes to repairing structural concrete damages and concrete spalls in seawalls and marine piles, epoxy injection resins and epoxy paste adhesives can be a reliable option.

These resins can provide long-lasting reinforcement to the affected area, helping to ensure that the seawall or pile can continue to withstand the stress and impact of waves and tides.

Additionally, the use of professional-grade equipment and accessories tailored to the specific conditions of each seawall repair is essential for ensuring both the quality and longevity of the restoration. This specialized equipment helps optimize the application of repair products, such as polyurethane foams and epoxy resins, ensuring they perform as intended in sealing leaks, filling voids, and stabilizing structures. By employing the right tools, contractors can address the unique challenges posed by each seawall’s environment, contributing to more effective, durable repairs that prevent future erosion, water ingress, and structural failure.

Understanding why seawall failure occurs and taking timely steps to prevent further damages is important to protect your land and any structures that may be impacted by ingress of water and shifting soils.

SealBoss Corp. has been providing concrete solutions and systems for seawall repair since 1988. With decades of experience, the company offers a range of proven methods designed to tackle various challenges, ensuring long-lasting protection and stability for both residential and commercial seawall structures.

Why Do Seawalls Fail?
Causes & Warning Signs of Seawall Failure

Poor Maintenance | Lack of Inspection to Detect Problems Early
Erosion, Washout, Sinkholes
Footing, Bulkhead Shift Due to Erosion
Cracks and Expanding Cracks in Seawall
Rust & Corroded Rebar Expansion
Drain Failure
Environmental Factors – Natural Disasters

Regular and Proactive Inspections and Maintenance: A Key Strategy to Prevent Seawall Damage

Executing frequent inspections and prompt maintenance are integral to extending the lifespan of your seawall. These preventative measures can save you from costly repairs in the long run by addressing potential issues before they escalate.

A significant issue you may encounter is the clogging of drain and weep holes. These are crucial components in the seawall’s design as they allow water accumulated behind the wall to drain. If clogged, water will build up, leading to added stress on the seawall and potential damage. This accumulation of water can soften and loosen the soil behind the wall, which could increase pressure and raise the water table. Such conditions might result in the formation of cracks in the seawall structure, thus creating new, unintended pathways for water flow and consequently causing soil erosion.

Understanding the Implications of Soil Erosion due to Accumulated Damages

Water migration through these new pathways, cracks, voids, and defects can lead to a gradual weakening of the seawall. As the wall undergoes consistent damage and erosion, its foundation may lose support and shift. This can be particularly problematic because soil erosion has the potential to create sinkholes. These sinkholes can further collect water, accelerating the decay process and potentially leading to the seawall’s failure.

Hence, regular inspection and maintenance can help identify early signs of soil erosion and structural damages, thereby preventing severe consequences and ensuring the longevity of your seawall.

WATER – ESSENTIAL YET DESTRUCTIVE

Water is the foundation of life on Earth, yet it also possesses the power to erode, weaken, and destroy. Nowhere is this duality more evident than in the construction industry—particularly in the behavior of concrete.

Water is essential to concrete’s formation, enabling its chemical transformation from a fluid, workable mixture into a solid, durable structure. However, once cured, unwanted water infiltration can become a silent destroyer, corroding reinforcing steel and compromising structural integrity.

Over time, this deterioration can render concrete structures unsafe and unusable. In essence, water is both a creator and a threat—one of the simplest yet most powerful forces shaping our built environment.

This article explores how water intrusion impacts concrete structures—specifically in parking facilities—examining common vulnerabilities, potential consequences, and proven solutions to mitigate damage. By understanding these risks and applying effective waterproofing techniques, engineers and contractors can extend the lifespan of concrete structures and ensure long-term durability.

Waterproofing Parking Structure Cracks

At a parking structure in Burlingame, California, the shotcrete structure and mat slab were exhibiting signs of unwanted ingress from the water table outside of the building.

While evidence of cracking was not necessarily present, efflorescence on the interior surface of the walls told the tale that the migration of unwanted groundwater was presenting a problem.

The structure is referred to as an Automated Parking Structure where building tenants can retrieve their automobiles by entering a code at the entry point to the structure and have their vehicles essentially “delivered” to them once the internal workings of the structure retrieve the vehicle. It becomes obvious from this description of the project that water has no place in the intricate electronic systems that comprise this facility but more so on or near the vehicles that live in this structure. Something needed to be done and a certified specialized contractor was called in to get the water mitigation handled.

The construction of the concrete is something to note, particularly with respect to the steel in place at a double mat (2 layers within the walls) of #9 and #11 bars at a spacing of 24” on center each way. This reinforcing steel is a sturdy configuration –and a lot of steel — all of which is susceptible to corrosion if water is present after the shotcrete’s cure out.

That amount of steel, if subject to corrosion, could, over time lead to spalling and eventually an overall degradation of the structure if left unaddressed.

A Permanent Fix for Persistent Leaks

The SealBoss 2400 super low viscosity acrylic gel injection system was the answer for waterproofing parking cracks permanently.

The 2400 system is extremely well suited to seal structures with very fine and hairline cracks and fissures.

The 24’ high walls needing injection stood atop a 6’ thick cast-in-place mat slab and were +/- 24” thick. Extending from the tops of the walls to grade were 4’ high cast-in-place ring beams. By drilling into the walls 22” (not all the way thorough) and setting mechanical packers into the drilled holes, the delivery of the SealBoss 2400 system was now possible to as was its migration within the substrate.

The environmentally friendly SealBoss 2400 offered outstanding penetration properties similar to plain water, allowing it to permeate throughout the wall’s network of fissures, no matter how tight and narrow. In some instances, the material would shoot out of pinholes and cracks barely visible to the naked eye several feet away, further showcasing its ability to navigate the concrete’s crack and pore network thoroughly and effectively. Once gelled, the material prevented unwanted water migration to reinforcing steel within the substrate.

Guide to Concrete Leak Sealing:

Polyurethane Grout vs. Hydraulic Cement & Crystalline Waterproofing

When it comes to repairing and reinforcing concrete structures against leaks, not all solutions are created equal. Each method has unique strengths and is suited to specific conditions, making it essential to choose the right approach for long-lasting results. This guide provides a detailed comparison of three popular options—polyurethane grout, hydraulic cement, and crystalline waterproofing—highlighting their advantages, limitations, and ideal applications to help you make an informed decision.

A Product Comparison

Hydraulic Cement, Crystalline Waterproofing, and Polyurethane Grout

Hydraulic cement, crystalline waterproofing, and polyurethane grout are distinct material groups, each with its own merits and uses. The choice between them should be a strategic decision guided by the requirements of your project.

Understanding Hydraulic and Crystalline Systems

Hydraulic cement and crystalline waterproofing solutions are often utilized due to their cost-effective nature and straightforward application process. They find common use in below-grade concrete structures like parking garages, basement walls, and manholes, where their primary role is to coat surfaces or seal leaking cracks, preventing water infiltration.

Despite their utility in surface-level repairs for static structures, these products share a key limitation – their inability to form a flexible seal that penetrates the depth of the structure. This makes them somewhat akin to ‘band-aid’ fixes – temporary, surface-level solutions.

Their limitations become particularly evident in the face of structural movement, including thermal expansion and contraction of substrates. Such movements often lead to the re-emergence of leaks over time, creating a cycle of recurring repairs. These patchwork solutions, although effective in the short term, can prove to be a less sustainable choice in the long run.

Polyurethane Grout: A Dynamic Solution

For structures prone to any movement over time, including expansion and contraction of materials, polyurethane grout outshines its service applied counterparts. The long-term benefits of polyurethane grout injection often justify the investment.

Let’s consider an illustrative example: a substantial concrete structure, such as below grade wall or potable water tank, several feet thick and reinforced with rebar, that has developed a crack.

In cases where the leak is not too severe – keeping in mind that polyurethane grout injection is the preferred, and often only method for handling aggressive or gushing leaks – a surface patch solution like a hydraulic cement or crystalline system could be employed to halt a minor leak initially.

While this approach may provide temporary relief, it falls short in addressing the fundamental problem – the unending cycle of water infiltration, migration, and trapped moisture within the structural fissures and crevices. The unresolved water intrusion not only propagates moisture migration throughout the structure, but it may also expose the reinforcing bars (rebar) to corrosive effects. This corrosion can lead to expansion, creating additional stress on the concrete structure, potentially worsening the initial problem.

Here is where polyurethane grout shines – Full depth penetration concrete leak sealing

With a full-depth injection of polyurethane grout, you can not only disperse any water inside the structure and seal the entire volume of the crack, but also safeguard the rebar in the process, eliminating the threat of future corrosion. The penetrating and water dispersing ability, flexibility, and durability of polyurethane grout make it an ideal solution for preventing future leaks. Unlike surface patch solutions, it offers a comprehensive, long-term resolution to the issue.

The Role of Structural Movement in Permanent Leak Sealing

The effectiveness of hydraulic cement and crystalline waterproofing significantly diminishes when it comes to dealing with structural movement. This is particularly evident in dynamic below grade concrete structures like parking garages, which experience thermal cycles, vibration due to heavy traffic, and may additionally be situated on expansive soil. Moreover, its high elasticity makes it perfect for application in areas prone to constant vibrations or expansions, like bridges, highways, and large commercial buildings. The recurring nature of leaks due to movements necessitates a structure penetrating and permanent solution: A professional polyurethane grout injection concrete leak sealing system.

The Final Word:

Making an Informed Choice

Selecting the right materials for your concrete leak sealing repair needs is crucial. The long-term benefits of polyurethane grout often make it a superior choice, especially for structures prone to any movement. Unlike its counterparts, it can withstand significant structural movement over time without losing its sealing capabilities.

As a trusted provider, we’re dedicated to guiding your decisions with reliable, professional, and detailed information tailored to your needs. Remember, making the best choice now will save you time and resources in the future.

Sealing Pipe Penetration Water Leaks at Multi Family Apartment Complex

Sealing
Pipe Penetration
Water Leaks

Multi Family Apartment Complex

Introduction

Water intrusion through pipe penetrations in apartment complexes can lead to significant structural damage, safety concerns, and costly repairs if not addressed promptly.

At a newly constructed apartment complex, persistent water leaks from a courtyard into an underground parking structure posed a serious challenge.

The leaking water caused concrete staining, erosion, and fire-stop material damage, jeopardizing the integrity of the building.

To tackle these issues, a certified SealBoss installer implemented a comprehensive and effective solution to seal the pipe penetration leaks.

Using advanced chemical injection grouting techniques and specialized SealBoss products, the contractor successfully resolved the problem, ensuring a watertight seal around the pipe penetrations and restoring the structure’s integrity.

This article details the step-by-step process and products used to address these complex leaks, offering insights into effective pipe penetration sealing solutions for multi-family apartment projects.

Multi Family Apartment Pipe Penetration Leak Stop

A certified SealBoss installer was engaged to resolve water intrusion issues at a new apartment complex, where water from a courtyard was leaking into the underground parking structure. This water was causing staining and erosion of the concrete floor and soaking into the fire-stop material. Upon investigation, it was found that rainwater and the courtyard’s irrigation system were the sources of the leaks.

The contractor employed a three-step approach to inject SealBoss 1510 Water Stop Foam into and around the affected pipe penetrations, successfully sealing the most problematic leak points.

Horizontal Blanket Injection: This technique filled the voids between the geofoam and poured concrete, creating a barrier around each pipe penetration. The contractor drilled strategically through the concrete deck and into the geofoam, placing injection packers to form an effective seal.
Area Draining and Packer Installation: After draining the area, injection packers were placed for a targeted injection of hydrophobic foam, addressing the initial leak sites.
Penetration Sleeves Sealing: A few days later, new leaks were detected around the pipe sleeves. For larger metal sleeves, the contractor drilled at a 45-degree angle toward the sleeve and injected SealBoss 1510 Water Stop Foam until a positive refusal around the sleeve was achieved. To contain the expanding material, SealBoss CanSeal Foam was used as a temporary backing and also to fill the voids between the concrete and ribbed steel sheeting.

SealBoss ® CanSeal Utility Foam is a specially formulated closed cell sealing foam — engineered to fully expand inside the applicator ‘gun barrel’. When the foam exits the tip of the gun it is already fully expanded, enabling you apply exactly as much foam as you need without the messy and undesired “mushrooming” experience you may have with most of the other ‘over the counter’ foam products.

Small Pipe and Pipe Penetration Leak Sealing Kits

SealBoss SealPipe Kit

For smaller pipe penetrations with poly sleeves, a Grout Injection Needle was utilized to inject foam into tighter spaces. Open-cell backer rod was inserted into the sleeve to contain the resin as the needle was withdrawn, allowing SealBoss 1510 Water Stop Foam to expand upward, effectively sealing the poly sleeve and stopping the leak.

This comprehensive approach enabled the contractor to stop the leaks successfully. Following the repair, the building owner was advised to re-evaluate the courtyard’s irrigation system to prevent future water intrusion into the underground parking area.

Sealing Tie Holes

Tie Holes a.k.a. Tie-Rod Holes in Concrete Structures

Introduction

Tie holes, also called tie-rod holes, are small openings in concrete structures created after removing tie rods used in formwork. While essential during construction, these holes can become problematic, especially when exposed to hydrostatic pressure, leading to leaks. A proven and reliable solution to this challenge is polyurethane polymer foam injection.

In this article, we dive into a real-world example of a contractor effectively sealing tie holes and addressing shrinkage cracks in water tanks for a rural water district. By utilizing the advanced SealBoss Injection System, the team achieved lasting results, showcasing the importance of specialized training, the right equipment, and strategic application in preserving concrete structures.

This guide provides valuable insights into the problem of tie holes, effective sealing techniques, and the critical role of expertise in ensuring durable repairs.

What are Tie Holes in Concrete Structures and How to Seal Them Permanently

Tie holes are small openings left in concrete structures after the removal of tie rods, which play a critical role during construction. Tie rods are essential components of concrete formwork—the temporary mold used to shape poured concrete. These rods ensure proper alignment and stability of the formwork during the concrete pouring and curing processes.

Over time, tie holes can become a vulnerability in the structure, as they may begin to leak when exposed to hydrostatic pressure. This typically occurs when water from an external source presses against the opposite side of the concrete structure, leading to potential water infiltration.

To address this issue, Polyurethane Polymer Foam Injection is widely regarded as one of the most effective and long-lasting solutions.

This advanced sealing technique permanently stops leaks in tie holes, providing durable protection against water penetration. Its efficiency and reliability make it a top choice for maintaining the structural integrity of concrete constructions.

By understanding the importance of sealing tie holes and utilizing proven methods like polyurethane foam injection, you can prevent water damage and extend the life of your concrete structure.

Sealing Tie Holes and Cracks

A Case Study in Effective Water Tank Repair

Polyurethane Polymer Foam Injection is an effective method to seal leaking tie rods permanently

In the world of construction, particularly in the construction of water tanks, shrinkage cracks and tie-holes are common issues that can lead to slowly weeping or even significant leaks. These problems are often accompanied by visible efflorescence, signaling a need for immediate and effective repair.

A recent project by a contractor in a rural water district expansion north of Atlanta, Georgia, perfectly illustrates how these challenges can be met with the right expertise and equipment.

Encountering the Challenge

During the construction of water tanks in this project, the contractor encountered both shrinkage cracks and tie-holes showing signs of leakage.

To address these issues effectively, the contractor sought on-site support and comprehensive systems training, specifically in the use of SealBoss 1510 NSF Hydrophobic Water Stop Foam and the P2002 High-Pressure Injection Pump.

The Training and Repair Process

The training began with a thorough inspection of the tank to identify the most actively leaking areas.

This was followed by a demonstration of the SealBoss Injection System application. The repair process involved a strategic approach to drilling holes:

The 1, 2, 3, 45 Degree Injection Method was used for the shrinkage cracks, and for sealing the tie-holes, a 45-degree hole was drilled 4 inches from the edge of each tie-hole until the steel insert was reached.

Preparation and Injection

Before the injection process, each drilled hole was pre-injected with water using a spray bottle. Given the ambient temperature of 38 degrees Fahrenheit, hot water (between 70 and 90 degrees Fahrenheit) was used for pre-injection to assist with the catalyzation time of the 1510 foam in the cold concrete. After flushing the holes, the installation of the SealBoss 13-100 AL Evolution Mechanical Packers commenced, followed by the injection process using the P2002 high-pressure injection pump.

Hands-On Learning and Independent Operation

The P2002 pump, known for its simplicity and drill-operated mechanism, was explained in detail. The training emphasized understanding injection pressure and the patience required for successful application.

Initially, the technician assisted with the pump operation, but within 10 minutes, the crew was able to inject independently.

Each packer was injected until there was positive refusal of material around each tie hole, and the same process was applied to the cracks.

Ensuring Long-Term Success

Once the crew gained confidence in operating the system, the focus shifted to cleaning and maintenance of the pump, ensuring its longevity and effectiveness for future projects.

Conclusion

This project north of Atlanta, Georgia serves as a prime example of how proper training and the right equipment can effectively address leaking tie holes and shrinkage cracks in new water tank construction.

The use of SealBoss 1510 NSF hydrophobic foam and the P2002 high-pressure injection pump, combined with hands-on training and a strategic approach to sealing, provided a durable solution to the problem of shrinkage cracks and tie-holes.

This case study not only highlights the importance of addressing these construction challenges promptly but also demonstrates the value of expert guidance and training in ensuring the longevity and integrity of water storage facilities.

Epoxy Crack Injection Concrete Repair

Epoxy Crack Injection
Concrete Repair

Epoxy Concrete Crack Injection Systems

Epoxy Crack Injection Resin can mitigate problems of cracked concrete with larger and fine cracks. ACI specifies cracks widths that are acceptable in structures under defined conditions. ACI 224R-012 provides a guideline for crack widths for reinforced concrete under service loads for new construction. Crack widths deemed acceptable may range from 0.004 in. (0.1 mm) to 0.016 in. (0.41 mm), and even smaller widths for concrete in wet or aggressive environments. These crack dimensions would be considered fine and hairline cracks.

Pushing the Envelope – SealBoss Epoxy Systems
– Resins, Pastes, Injection Ports and Pumps –

Epoxy Crack Injection

Cracking does not always affect structural performance, but it can adversely affect the durability of structures.

Common causes of concrete cracking are post cure and drying shrinkage, thermal stress, chemical reaction caused by alkali-reactive silica & sulfates, freezing and thaw cycles due to water expansion, corrosion of steel rebar, settlement, load stresses, construction short comings such as design and construction errors.

The incorporation of steel reinforcement within structural concrete allows these elements to function under both compression and tension, frequently resulting in tension-induced fracturing of the concrete in certain regions.

Water is a major contributor to concrete corrosion in parking garages, bridges, industrial facilities and more. Water, chloride and carbon dioxide can migrate deep into the structure initiating corrosion of the reinforcement structure.

Water ingress, facilitated by fissures or compromised joints, often carries corrosive substances and chlorides that contribute to the degradation of concrete and the corrosion of steel reinforcements and rebar. Fortunately, epoxy concrete crack injection can address many of these concerns in structures exhibiting signs of such issues. Employing a proficient concrete repair team can frequently circumvent the need for a complete teardown.

SealBoss Epoxy Resins

SealBoss Epoxy Crack Injection resins for structural crack repairs conform to ASTM C881 specifications, with appropriate viscosities for the crack widths. The bond strength of epoxy to clean concrete is greater than the tensile strength of concrete itself.

Wider cracks may require a higher viscosity epoxy, small cracks a lower viscosity injection resin. Depending on the requirements, viscosities may range from approximately 150 to 600 cps at room temperature.

SealBoss Epoxy Crack Injection concrete repair can be performed with SealBoss Epoxy Cartridge Systems or SealBoss epoxy bulk resins using air guns, hand-actuated delivery systems, or dual-component injection electric or air-driven pumps.

Prior to repair, the structure must be carefully examined to establish that epoxy crack injection is indeed the correct method to regain the desired structural integrity. The cause of cracking must be determined. Cracks must be identified and the allowable crack width needs to be established. The width of cracks can be measured by using crack gauge cards. In some instances it may be recommended to measure the expansion and contraction cycles of a crack. To determine the depth and cause of cracking, core samples can be taken and examined by petrographic and chemical testing. In addition, nondestructive testing (NDT) ultrasonic pulse velocity can be used to measure the depth of cracks.

Once it has been established that epoxy concrete crack injection is the chosen method of repair, the SealBoss Epoxy Injection System can be utilized to restore the structural integrity of the concrete.

SealBoss ® Surface Mount Injection Ports

Surface-mounted injection ports are typically adequate for injecting most cracks. However, badly deteriorated concrete or higher injection pressures may require the use of drill-in or hammer-in plastic ports or even mechanical packers. Surface ports, aka plastic tubing ports, are glued on the surface over the open cracks using SealBoss epoxy paste adhesive. The injection ports are typically installed at a spacing that is equal to or slightly narrower than the depth of the crack. Hairline cracks require closer spacing than wider cracks.

Wire brushing and vacuuming the crack surface along the crack is often sufficient for surface preparation. In areas of badly deteriorated concrete, pressure washing, grinding, and V-grooving may be specified.

After the surface has been cleaned, surface ports are installed. Sealboss 4500 crack-sealer epoxy paste will be used as surface port adhesive and be applied on the face of the crack between and around the ports.

Once the injection ports are installed, Sealboss 4500 crack-sealer epoxy paste is applied on the face of the crack between and around the ports. To contain the epoxy resin in the crack until it hardens, it is a good practice to seal cracks on all sides of the substrate if possible.

Begin the Epoxy Crack Injection at the Point of the Structure

As soon as the epoxy appears at the next higher port, the current port is capped and the injection is continued from the next port. Multi port injection may be used in most epoxy injection environments. Typical injection pressures are between 50 to 100 psi (3 to 6 bars), with very fine cracks requiring pressures of over 200 psi (12 bars).

Epoxy resins are temperature sensitive. At higher temperatures resin viscosity decreases, but reaction time increases. For best performance during application, it is advised to keep the resin at room temperature or slightly above during injection.

After the injection resin has cured, the epoxy paste adhesive is removed from the surface of the concrete.

Quality assurance and control measures include visual observation of the injection process and product consumption, testing the injection equipment for mix ratio, taking core samples and testing repaired cracks using nondestructive testing methods.
