Chemical Grouting

Understanding Chemical Grouting

Chemical grouting is a cutting-edge technique that has been gaining traction in various industries over the past decades, primarily for its prowess in addressing a myriad of structural, environmental, and geotechnical challenges. Often, these challenges are intertwined with issues of water migration or infiltration.

The Power of Polyurethane Chemical Grout

At the heart of this process are polyurethane chemical grouts, a potent polymer material that springs to life upon contact with water. This interaction activates the grout’s hydro-active properties, prompting it to expand and solidify. The result? A robust, watertight barrier and seal for concrete structures that can also be used to fortify loose, granular soils in geotechnical applications. Given its versatility, it’s no wonder that these grouts are the go-to solution for a diverse set of building structure and soil related repair scenarios.

Acrylate Gel Chemical Grouts: The Ultra Low Viscosity Solution

Then there’s the acrylate gel chemical grout, known for its exceptionally low viscosity. This characteristic allows it to seep into the tiniest of cracks and loose soils with remarkable efficiency. Once settled, it transforms into a flexible and resilient gel, making it a prime choice for some challenging water sealing and soil stabilization scenarios demanding the super low viscosity properties of the injection grout.

Your Quick Guide to Chemical Grouting

Chemical grouting is an innovative process employed across various industrial sectors to rectify or prevent a wide array of structural, environmental, and geotechnical issues, often – but not always – correlated with water migration or water infiltration.

Navigating the world of chemical grouting can be daunting, given the plethora of grouting agents on the market. However, a few stand out for their unparalleled efficacy and adaptability:

Water-Activated, Hydro-Active Polyurethane Chemical Grouts: These are your best bet for creating strong barriers or solidifying soils.
High-Strength Two-Component Water-Blown Polyurethanes: Known for their strength, they’re a reliable choice for demanding applications.
Super Low Viscosity Acrylate Gels: Ideal for situations requiring a fine touch, these gels are both effective and adaptable.

In essence, each of these grouting agents brings a unique set of benefits to the table, making them indispensable tools in the realm of chemical grouting.

Types of Chemical Grouting Polymers

In broad terms, there are Two Categories of polyurethane grouts:

Flexible polyurethane grouts: These grouts are often used to fill voids and cracks in the soil or structure, creating an impermeable, flexible seal that can withstand slight movements without cracking.
Rigid polyurethane grouts:Typically used for soil stabilization and lifting concrete slabs, these grouts solidify into a strong, durable material capable of bearing significant loads.

Applications of Polyurethane Chemical Grout

With its diverse properties, polyurethane chemical grout finds applications in a wide range of scenarios. Here are some of its most common applications:

Sealing and Waterproofing

Polyurethane chemical grout serves as an excellent waterproofing agent. It creates an impermeable barrier that prevents water infiltration, making it an ideal solution for:

Tunnel and Dam Sealing: Polyurethane grout is often used to seal leaks in tunnels and dams.
Below Grade and Foundation Waterproofing: Polyurethane injection grout is used to effectively seal basements and foundations. The products are used for crack injection and curtain and stage grouting techniques to seal structures permanently.

Ground and Soil Stabilization

The grout is injected into the soil, where it expands, displacing loose soil and filling voids. It then solidifies, creating a stable, durable mass that strengthens the overall structure.

Seawall Repair: Polyurethane grouting is an effective solution for filling voids and stabilizing soil behind seawalls, reducing the risk of further washouts and damage to structures.
Permeation and Consolidation Grouting: It is also used to solidify loose, unconsolidated soils around structures and on slopes, thus preventing soil movement and erosion.

Concrete Lifting and Leveling

Rigid polyurethane grout can be used to lift and level concrete slabs, making it a popular choice for:

Roadway and Sidewalk Repair: The grout can be injected beneath the concrete to lift and realign sagging or uneven roadways and sidewalks.
Building Foundation Leveling: Polyurethane grouting is also employed to level building foundations that have settled or shifted over time.

Applications of Acrylate Gel Chemical Grout

Acrylate gel grouts are widely utilized due to their exceptional flexibility and permeation characteristics. Here are some typical applications:

Curtain Grouting: Acrylate gel grouts can be used to create an impermeable barrier or “curtain” around tunnels, basements, or other structures, preventing water ingress. Acrylate gel grouts are ideal for sealing fine cracks in concrete and other structures, thanks to their super low viscosity and flexibility.

Water Ingress in Corrugated Tunnel Sealed

The University of Leicester enlisted the services of a U.K.-based specialty repair contractor to evaluate and rectify a steel corrugated tunnel/pipe approximately 1.8 meters in diameter.

The tunnel was exhibiting signs of persistent and significant water intrusion due to damage caused by corrosion, which led to the formation of cracks and perforations at the base of the duct.

The contractor devised and implemented a solution that could be applied from the confined interior space of the tunnel. The aim was to extend the lifespan of the structure by an estimated 25 years.

Given the substantial degree of water ingress from the elevated water table, a solution was needed that would not only stop the current water flow but also provide a robust barrier against future water infiltration and leakage.

The contractor identified a proven hydrophobic, hydro-active polyurethane water stop foam resin as the most suitable solution to tackle the fractures showing severe pressing water conditions.

Sealboss 1510 Water Stop Foam, NSF certified and activated by the 15x Accelerator, was the selected chemical grout to mitigate the severe and pressing water conditions.

The advantage of using this specific waterproofing injection grout in sealing the corrugated tunnel stems from its ability to seal not only wide, gushing water leaks but also the smallest of pores and capillaries in building elements that might otherwise allow water to seep to the surface.

The low viscosity of SealBoss 1510 chemical foam grout, coupled with the specially formulated SealBoss 15X Accelerator – which can be mixed at ratios ranging from 2% to over 20% by volume with the resin – enables a range of reaction profiles. These range from slow absorption into the concrete building components, sealing all capillaries and pores, to rapid water stop high-foamer expansion for sealing larger gaps and voids.

Carefully regulated addition of the accelerator allows for controlled expansion from nearly no expansion to forty times expansion. Due to its controlled expansion, the resin will either cure to form a tough semi-flexible seal or a compression seal gasket when expanding at pressure.

Following the injection as per specification, the corrugated tunnel repair now provides a watertight seal to the concrete, effectively preventing further deterioration of the building components due to water infiltration and seasonal frost.

SealBoss Swell Caulk is a single-component, water-activated polyurethane-based waterstop and leak-sealing caulk paste specifically designed to halt water ingress through concrete cold joints and other construction joints.

Its hydrophilic formulation reacts with water, causing a controlled and steady expansion of its volume. The product is inherently sticky by design to easily self adhere to the substrate.

Packaged in two formats, Swell Caulk Cartridges are compatible with a standard caulk gun, while Swell Caulk Sausages require an industry-standard sausage gun for application.

How Does a Caulk Grade Swelling Waterstop Work?

Swell Caulk’s unique formulation allows it to self-adhere to dry concrete surfaces during application, irrespective of whether the substrate is rough or smooth. It requires no mechanical fastening or additional adhesives, seamlessly accommodating any uneven substrate conditions.

SealBoss Swell Caulk is extremely effective in sealing leaks and stopping water migration based on its outstanding swelling capacity .

It can expand up to 350% of its original volume on contact with moisture, demonstrating excellent pliability, plasticity, and flexibility to mold itself to uneven and rough surfaces.

Swell Caulk as a Compression Seal

As it swells, SealBoss Swell Caulk forms a compression seal, establishing a pressure-positive seal against all surfaces of the concrete in cold joints and construction joints. This action effectively blocks water flow through the joint, creating a permanent seal.

Swell Caulk can withstand high hydrostatic pressures (120ft / 36 m) when installed to specification.

The Concept of a Cold Joint

A cold joint is an area of weakness in the concrete, similar to a hairline fracture, caused by a lack of bonding / cohesion in otherwise monolithic concrete caused by an interruption, delay or intentional design process in the concreting operation. A cold joint is created when the first batch of concrete has begun to set before the next fresh batch is added. The two batches do not cohere or bond together and create a fine channel for water to migrate.

Dam Repair – Active Leaks Sealed

Dam Repair
Active Leaks Sealed

Addressing Dam Leakage

Several factors can play a role in the development of cracks in concrete dams. The natural shrinking of concrete, geological stresses, and inadequate soil compaction during construction all play their part. The persistent positive water pressure means that even the smallest of these cracks and fissures can become avenues for water leaks. As water continues to seep through, the cracks inevitably widen over time, potentially leading to significant water loss and a progressive deterioration of the dam structure.

Earthen dams also face the risk of significant water loss through leakage. The potential culprits are often inadequate compaction of fill dirt, faulty seams, and leaks forming underneath the dam’s breastwork. Seepage can undermine the stability of earthen dams, leading to safety concerns and operational inefficiencies.

As with most structural defects, water leaks will continue to increase until corrective action is taken.

Dam Repair – Sealing Active Leaks

Innovative injection solutions like SealBoss Water Stop Foams and Polyurethane Injection Resins have been utilized for dam repair for over three decades. Successfully used to seal leaks in both concrete and earthen dams, these materials have proven invaluable in enhancing the resilience of dams, preventing water loss, and extending the lifespan of these significant structures.

Inject the Epoxy Resin:
Once the adhesive paste is set, begin the injection process. Using the SealBoss P3003 Epoxy Injection Pump, inject the low-viscosity SealBoss 4040 Epoxy Resin into the cracks at the lowest speeds, just enough to move the epoxy resin into the crack and allow for continuous flow and deep penetration of the material.
Use SealBoss 4050 SLV for Micro-cracks:
For extreme micro-cracks, consider using SealBoss 4050 SLV super low viscosity epoxy to ensure deep penetration into these smaller cracks.
Monitor the Injection:
Watch for the epoxy material to appear in the next port, indicating sufficient filling of the current crack and time to cap the port and move onto the next.
Curing:
Allow enough time for the epoxy resin to cure fully within the cracks, restoring and reinforcing the structural integrity of the concrete foundation.
Finish the Surface:
After the material has fully cured, grind off the ports and smooth down the surface to achieve the desired look and finish.

These procedures should be done carefully and patiently, keeping in mind that the main goal is to ensure a completely sealed and controlled environment for the epoxy to set up properly.

Foundation Crack Epoxy Injection | Transmission Towers – Procedures

To manage the structural integrity, hairline cracks and micro fissures in the concrete foundations are injected with low viscosity SealBoss 4040 epoxy resin. The odourless SealBoss 4500 epoxy paste serves as a surface seal and adhesive for SealBoss Tri-Base surface mount plastic ports equipped with caps to prevent epoxy resin back-flow. For operations in cold conditions, it is advised to precondition the epoxy products to warmer temperatures to facilitate a quicker setting time. When the environment is cold and time permits, mounting the surface port and applying the crack paste a day prior to injection can ensure an appropriate seal around the cracks and good port adhesion to the concrete substrate.

Once the ports are securely fastened and the paste adhesive has set, injection can commence. By using the lowest speeds on the P3003 epoxy pump, sufficient to push epoxy resin into the crack, it allows for continuous flow and deep penetration of the material through the crack.

In situations where SealBoss 4040 epoxy resin, a low viscosity 2:1 material is used for most crack dimensions, SealBoss 4050 SLV super low viscosity can penetrate even deeper, reaching into the farthest corners of extreme micro-cracks.

Once the material is visible in the subsequent port, it serves as a signal to halt the application, cap the port, and proceed to the next one. The primary principle of epoxy injection is to maintain a completely sealed and controlled environment to allow the epoxy to set up and restore the structural integrity of the concrete.

After the epoxy has fully cured, contractors can remove the ports and smooth down the surface to achieve the desired aesthetic look.

The Indispensable Role of Mockups in Injection Waterproofing

Introduction

Injection waterproofing has become a crucial technique in the construction and maintenance of various structures, from residential homes to commercial buildings, and even infrastructure projects such as tunnels and bridges. This method is employed to improve the water-resistance of structures and protect them from the detrimental effects of water seepage. A pivotal step in ensuring the effectiveness of this waterproofing technique is the creation and utilization of mockups. This article aims to delve into the importance of mockups in injection waterproofing.

Understanding Injection Waterproofing and Mockups

Before discussing the importance of mockups, it’s essential to understand what injection waterproofing entails. This technique employs the strategic injection of waterproofing materials such as polyurethane or epoxy resins into various aspects of a structure. These materials are inserted into pores, cracks, and joints within the structure, and even into the space surrounding the structure, extending to the dirt substrate. This comprehensive approach serves to effectively block the ingress of water, creating a formidable barrier against potential water seepage. It’s a crucial process that can enhance the longevity of the structure and safeguard it against dampness, water damage, and structural integrity problems.

In this context, a mockup can be understood as either a functional replica of the structure or, more commonly, a carefully selected segment of the existing structure.

This designated part is chosen for its representative nature, closely mirroring the conditions and real-world challenges anticipated during the comprehensive execution of the waterproofing injection project. Thus, it offers a realistic simulation of the full-scale scenario, providing valuable insights for the upcoming task.

The Importance of Mockups in Injection Waterproofing

Testing the Feasibility of the Waterproofing Solution:
The first and foremost reason to create a mockup is to validate the feasibility of the chosen waterproofing solution. A mockup can test whether the proposed waterproofing material will adhere correctly to the structure’s material, effectively seal its cracks, or withstand its environmental conditions. This step is critical to avoid costly mistakes and ensure the waterproofing solution’s efficacy.
Improving Accuracy and Predictability:
A mockup can help determine the exact amount of waterproofing material required and the optimal injection points and pressures. This can reduce waste and improve efficiency in the actual construction phase. Moreover, the mockup stage can reveal potential issues that may arise during the application, enabling teams to address them proactively.
Enhancing Training and Communication:
Mockups are instrumental in training the application team. They provide a hands-on experience, enabling team members to familiarize themselves with the application process, understand the structure’s complexities, and gain confidence before proceeding to the actual project. Furthermore, they facilitate clear communication among the project’s stakeholders, ensuring everyone understands the proposed solution and its implementation. architectural projects.

Conclusion

The use of mockups in injection waterproofing offers a range of significant advantages, from improving project accuracy and predictability to enhancing team training and communication. By representing a vital stage in the waterproofing process, mockups can significantly increase the chances of project success, making them an indispensable tool in contemporary construction practice. Therefore, it’s safe to conclude that any injection waterproofing project can immensely benefit from investing time and resources into creating and using a detailed, accurate mockup.
