Pressure Grouting with Polyurethane Chemical Grouts and Injection Lances

Introduction:

Pressure grouting is an essential technique in construction and civil engineering, enhancing the strength and stability of various structures by stabilizing the subsoil. This method involves injecting grout into voids or cracks in concrete, soil, or rock to fill them and improve their load-bearing capacity. Among the many types of grouts available, polyurethane grouts, a.k.a. chemical grouts, stand out for their unique properties and versatility. In this article, we will explore the intricacies of pressure grouting, focusing on the benefits and applications of polyurethane grouts, as well as the use of injection lances for optimal grout delivery.

What is Pressure Grouting?

Pressure injection grouting in geotechnical applications involves injecting grout under pressure into strata of soil to strengthen the soil by compaction, adhesion and by filling voids, cavities, and fissures. This technique is commonly used for:

  • Foundation Stabilization: Strengthening the foundations of buildings and other structures
  • Soil Stabilization: Enhancing the load-bearing capacity of soil
  • Leakage and Erosion Control: Sealing leaks in soils and structures such as earthen dams
  • Void Filling: Filling cavities or voids in rocks or soil

The success of pressure grouting depends on the type of grout used, the injection pressure, and the specific site conditions.

Seawall Repair with Polyurethane Foams - Plural Component vs Single Component Foam

This article contains an excerpt from the “SealBoss Concrete Solution Network Podcast – Seawall Repair | Bulkhead Repair | Erosion Control | Permeation Grouting”,  featuring Jerald Sargent of Slabjack Geotechnical.  Jerald has over 30 years of experience in the slabjacking and geo-technical industry. If you’d like to listen to the complete conversation, an audio version of the podcast is posted at the bottom of the article.

In this podcast we talk about the use of single and plural component foams for seawall repairs. 

Both foam types have their place in seawall repair but the contractor needs to have a good understanding of their respective characteristics and area of application.

Single component (accelerator activated) foams offer outstanding crack sealing and good soil penetrating, permeation and soil aggregate stabilizing properties.

Plural component foams are excellent void fillers, support and lifter foams, predominantly used for slabjacking and slab lifting.

Single Component Foams are Preferred for Soil Permeation and Soil Consolidation — Plural Component Foams are Good for Filling Voids in Certain Applications

In the following Jerald discusses the use and limitations of Plural Component Foam.

Jerald Sargent: …Sometimes plural components make a lot of sense… where there’s obvious gaps behind the wall or maybe in a you know in a big boulder type of Bulkhead where they just use big rock rather than poured concrete. So plural components are good for filling voids in there and helping to lock  [larger] aggregate together…

In most poured concrete walls we stay away from plural component simply because of the risks associated with it.

Going right along with that, one of the things that plural component is not appropriate for is injecting underneath the walls…

There’s virtually no permeation [into the soil] involved with plural component polyurethanes. It’ll [the soil] take up, it’ll absorb a little bit push through a little bit of that but it will not do it to the point where you have a solid structure built below the wall itself.

And I think that it is really important to understand the real limitation of the plural component polyurethane. And we use hundreds of thousands of pounds of a year in our slapjack in operation.

But it really isn’t appropriate in most cases to do a poured concrete wall [soil] stabilization.

Concrete Leveling Polyurethane Foam

Concrete Leveling Polyurethane Foam

SEALBOSS-SLAB-LIFTING-POLYJACKING-FOAM-JACKING

Introduction to Concrete Leveling Polyurethane Foam

Concrete leveling polyurethane foam offers an innovative solution for maintaining the integrity of concrete slabs. This versatile material addresses various underlying issues that can cause slabs to become uneven or unstable.

Erosion

Erosion is a primary cause of concrete slab instability. It occurs when water washes away the soil beneath the slab. This can happen due to several factors:

  • Improper Property Slope: Water directed towards the slab due to a slope can erode the soil

  • Gutter Runoff: Inadequate drainage systems can cause water to seep into the soil

  • Sewer Line Breakages: Wastewater from broken sewer lines can contribute to soil erosion

Substandard Soil Compaction

The foundation of a concrete slab depends heavily on the compaction of the underlying soil. Proper soil compaction reduces the space between soil particles, creating a solid base for the slab. If this process is skipped or done incorrectly, the slab is prone to sinking over time.

Expansive Soil

Expansive soils, which swell when they absorb water and shrink as they dry, pose a significant challenge to concrete slabs. This cycle of swelling and shrinking can cause the slab to lift, sink, and eventually crack, compromising its stability and appearance.

Tree Roots

Large trees near concrete slabs can also affect their stability. Tree roots can absorb water from the soil under the slab, causing the soil to shrink. Additionally, as these roots decay after the tree’s death, voids can form beneath the slab, leading to further instability.

Understanding the Causes

Understanding the factors that lead to concrete slab issues highlights the importance of using concrete leveling polyurethane foam. This solution not only addresses the root causes of slab instability but also provides a long-lasting fix, ensuring the durability and safety of concrete structures.

The Repair Process Overview

Concrete leveling foam, a two-component, high-strength polyurethane material, is pumped beneath sinking concrete slabs, sidewalks, driveways, or patios. It provides a strong foundation by filling the void and elevating the sunken concrete while expanding. The process is also known by various terms like polyjacking, concrete lifting, slab jacking, foam jacking, foam lifting, all achieving the same goal.

Concrete Leveling Polyurethane Foam

The Process in Detail

Leveling and Lifting: Utilizing the concrete slab itself to deliver polyurethane foam, our method raises the concrete, fills voids, and stabilizes soils. A small hole is drilled into the slab, into which a tapered delivery port is inserted. The injection gun, connected to the port, pumps the polyurethane material through the port and slab, with the foam expanding within seconds, compacting loose soil and lifting the concrete.

This highly accurate and simple process is executed via incremental injections. The lifting foam fully expands within a brief period, allowing for monitored elevation and prevention of over-raising the concrete slab.

Applications of Concrete Leveling Foam

Void Filling: Polyurethane foam is not limited to addressing concrete settling. It can also fill voids under slabs resulting from excessive settling or washouts. It imposes 15-25 times less weight than traditional mudjacking or cementitious grout mix, easing the pressure on a failed subgrade.

Joint/Slab Stabilization: Slab stabilization is critical when slabs lack support and are susceptible to cracking under heavy loads. This specialized foam, designed for joint/slab stabilization, fills voids to provide support and eliminate movement. Its slow reaction time and minimal expansion strength allow for thorough coverage under the slab or along a joint.

Concrete Leveling Polyurethane Foam Injection vs. Mudjacking

Concrete leveling foam offers several advantages over mudjacking, a method developed approximately one hundred years ago. Mudjacking is typicall messier and requires substantial machinery to transport and pump the heavy slurry under the slab. Any spillage can result in a significant mess. Mudjacking slurry, a mixture of sand, cement, and other natural materials, weighs approximately 100 pounds per cubic foot, compared to concrete leveling foam’s weight of 2.5 to 4 pounds per cubic foot. Moreover, the much larger 2-inch holes required for mudjacking can crack the concrete slab and provide an avenue for roots to penetrate.

Unlike mudjacking slurry, concrete leveling polyurethane foam is hydrophobic, inert, and waterproof, ensuring its structural integrity remains uncompromised when in contact with water. Conversely, mudjacking slurry can wash away upon contact with water, leading to further slab sinking.

Finally, concrete leveling foam operates with rapid effectiveness and exhibits prolonged durability. Upon being injected beneath the slab, it solidifies within mere minutes. On the other hand, mudjacking demands an extended application duration and frequently yields a shorter effective lifespan, which, dependent upon environmental factors and particular conditions, may only persist between 2 to 5 years before the slab descends again. This stands in sharp contrast to the notably extended typical longevity offered by concrete leveling foam.

SealBoss Slab Lifting Systems

Slab Lifting
Soil Compaction & Consolidation

Introduction:

Ensuring concrete structure stability often depends on addressing the underlying soil conditions. Techniques such as slab lifting, soil compaction, permeation, and consolidation injection systems provide the necessary support.

Using methods like polyurethane foam injection and permeation grouting, we can achieve efficient, non-invasive, and durable solutions for various soil and slab issues.

Slab Lifting, Soil Compaction, Permeation, and Consolidation Injection Systems

Effective void filling and slab lifting procedures can provide for stable subsoil to adequately support the structure above. If there are concerns about the subsoil’s stability, soil permeation grouting should be considered, provided the soil composition is suitable.

Slab Lifting and Void Filling

Slab lifting and void filling involve injecting structural polyurethane foam into voids beneath settling or uneven concrete slabs. This proven method stabilizes slabs without the need for excavation and adds minimal weight. Known as slab jacking, foam jacking, polyurethane concrete raising, poly jacking, or poly leveling, this technique offers several advantages over traditional mud jacking methods.

Advantages of Polyurethane Foam Injection

  • Non-Invasive: No need for excavation, preserving the surrounding landscape and structures

  • Lightweight: Adds minimal weight compared to other materials, reducing the risk of further sinking

  • Quick Setting: Polyurethane foam sets rapidly, allowing for quicker project completion

  • Durability: Provides long-lasting stability and support.

Permeation Grouting and Soil Stabilization

Permeation grouting and soil stabilization are performed by injecting a single-component, low-viscosity polyurethane hydro-active foam, catalyzed with an accelerator to specification, into the soil. This is done through injection packers, lances, or grout injection needles to consolidate and compact the substrate, increasing stability by binding soil particles together.

Procedure and Considerations

  • Soil Analysis: Before any permeation grouting procedure, the soil composition must be analyzed to predict the effectiveness of the treatment

  • Injection Process: The foam is injected into the soil to fill voids, stabilize loose soil, and enhance the load-bearing capacity of the ground

  • Equipment Used: Injection packers, lances, and grout injection needles are utilized to deliver the foam precisely where needed

Conclusion

SEALBOSS INJECTION LANCES

Slab lifting, void filling, and permeation grouting are essential techniques for maintaining and restoring the stability of concrete structures. By using advanced polyurethane foam injections, these methods provide efficient, non-invasive, and durable solutions for various soil and slab issues. Proper soil analysis and the right application of these techniques ensure the long-term stability and safety of the structures.

How to Fix Foundation Cracks

Popular Mechanics – Pop Mech Pro, Publishes Article with Detailed Pictures about “How to Fix Foundation Cracks”, using the SealBoss Crack Repair Method with Specialized Leak-Sealant and Injection Packers:

Concrete cracks have been an issue since the beginning of concrete construction three millennia ago. The article explains that modern concrete lacks self-healing properties, which causes cracks to worsen over time and impacts both homeowners and engineers.

Popular Mechanics’ century-old building in Easton, Pennsylvania, suffered from cracked concrete until local contractor repaired it. They used a specialized leak-sealant from SealBoss and ordinary tools to fill and seal the cracks, preventing further water entry and degradation.

The article discusses the SealBoss 1510 Water Stop Foam solution for fixing concrete cracks, a common issue affecting many structures from homes to bridges.

The article highlights how modern concrete deteriorates over time due to water seepage through cracks.

  • “After the water-stopping material has hardened into a plastic foam, the contractors removed it from the wall and floor with putty knives and scrapers. They removed the packer with a socket and socket wrench, then filled the remaining hole with mortar. With that, the job is complete.” 

     Popular Mechanics, Roy Berendsohn

The solution presented in this article and involves a straightforward repair method demonstrated by the contractor, using ordinary tools and SealBoss 1510 specialized leak-sealant from SealBoss. The process includes drilling holes along the crack, inserting injection ports, and injecting an expanding liquid polyurethane resin mixed with an accelerator to seal the crack effectively.

This method has proven successful in preventing further leaks through the foundation of the century-old building occupied by Popular Mechanics in Easton, Pennsylvania, showcasing its effectiveness in concrete crack repair.

  • “We were amazed at the simplicity of the process and the good results it produced–we haven’t seen any further leaks through the foundation since the two men completed their work.”

Parking Garage Crack Injection | Leak Sealing Repair

Parking Garage Crack Injection

Structural and Leak Sealing Repairs

Introduction:

For effective and long term parking garage crack injection repair, the use of specific injection products for waterproofing and structural crack repair is pivotal.

For leak sealing, polyurethane foam resins, hydrophilic gels, and acrylate / acrylic gels are commonly employed. These resins, when injected, either react with water to form a foam that expands or create a gel product respectively, filling voids and sealing against further water ingress. This method not only prevents water penetration but also adds to the structural integrity of the parking facility.

On the other hand, for structural strength crack injection, epoxy resins are predominantly used. These resins are known for their high-strength bonding capabilities, effectively sealing cracks and restoring the concrete’s original strength. Epoxy resins are particularly advantageous in load bearing environments, providing strength and restoring the concrete’s structural integrity.

Both types of injection product groups are crucial in extending the lifespan of parking structures, ensuring they remain safe and functional for daily use.

Parking Garage Crack Injection Technology

For over three decades, SealBoss Crack Injection Systems have been at the forefront of providing effective solutions for structural repairs and sealing leaks in cracks and joints within parking garage structures. These systems have proven successful in not only preventing water ingress but also in preserving the integrity and functionality of parking facilities.

How to Seal Leaks in Voids, Cracks, Joints, and Seal Around Beams

In a technical support role for a leading infrastructure repair company, the job often involves providing assistance to clients on a wide array of repair projects. These projects range across a diverse spectrum, including concrete repair, waterproofing, slab lifting, soil stabilization, and permeation grouting.

Recently, there was an instance of providing consultation to a contractor. The focus was on addressing water leaks by injecting materials into voids, cracks, joints, and beam pockets that had previously been treated with mastic grout.

The area where the leaks persisted were directly below the sidewalk where the concrete meets the asphalt driveway.  After inspecting the above ground conditions closely it was determined that the main source of the water intrusion were gutter downspouts. There were no drains installed to manage the directional flow of rainwater away from the structure.

Now that the source and path of water ingression had been established, polyurethane pressure injection of the affected areas was confirmed to be the correct solution to seal the leaks. 

The first areas that needed to be sealed were leaking beam pockets which had been previously filled with a mastic patch grout. Over a 30 year period there had been multiple previous attempts by various contractors to repair the leaking areas. No records were available on the various works that had been performed.

It was decided to inject through the wall to the back side of the structure to cut off any water before it could find its way into the beam pockets. This method combines void fill and permeation grouting as product is injected beyond the structure into a space that in this instance is confined by concrete / steel, asphalt and dirt. As the foam disperses under pressure injection and during expansion, it partially migrates / permeates also into the dirt further enhancing the ability to seal the void.

Using two strategically placed SealBoss Evolution 13-100 AL packers, the contractor injected 1510 Water Stop Foam, catalyzed with 10% 15x Accelerator,  at several intervals, permitting the resin to expand to a dense foam creating a seal and protecting the beam pocket from any water intrusion from behind the wall. 

The injection process was monitored from the inside and outside and the contractor stopped injection once air bubbles and water were observed coming up through the asphalt driveway. Expanding foam displaced water in the affected area. Injection was continued at a slow rate until water displacement  finished and increasing resistance indicated full penetration.

Next, the contractor injected all visible and leaking cracks some of which at one point had been injected with a structural / rigid epoxy which had failed. Reason of epoxy failure was determined as either lack of bond due to actively leaking cracks during epoxy injection and/or failure due to crack movement such as contraction and expansion. Polyurethane injection is the preferred method to address actively leaking and water bearing cracks, especially in areas where structural repairs are not necessary. The two foot thick wall was injected with 1510 leak-seal foam in intervals till the crack showed refusal of the resin.

How to Fix a Leaky Basement

Water damage is a serious issue that can have devastating effects on your home. Not only does it decrease the value and livability of your property, but it can also compromise the structural integrity of your home. A leaky, damp basement is particularly concerning, as it creates a breeding ground for harmful mold and bacteria that can cause health issues for you and your family.

In addition, a damp basement can attract pests such as termites and rodents, causing further damage and infestations. It’s crucial to address any water damage in your basement as soon as possible to avoid these issues and prevent them from escalating. With the right tools and procedures, you can successfully mitigate basement leaks and protect your home from further damage.

Cracks and Cold Joints are Known Areas for Basement Leaks to Occur

Unsealed cracks and cold joints in your basement, or any below grade spaces, can be a major source of water damage, as they provide an easy pathway for water to enter your home. This can result in flooding, which not only damages your belongings but also compromises the structural integrity of your home. In addition to damaging walls, coverings, furniture, and storage items, water can also cause electrical hazards and increase the risk of fires.

Common Causes for Concrete Foundation Leaks and Wall Cracks

Concrete wall cracks, especially in basements, can be caused by a variety of factors that compromise the integrity of the structure and allow water intrusion. Here are some common causes:

  • Inadequate Construction
    – Insufficient Material Quality: Using substandard materials or improper mixing ratios can weaken the concrete, making it more prone to cracking.
    – Poor Waterproofing: In new homes, improper waterproofing techniques can lead to leaks and cracks.
  • Deteriorating and Stressed Concrete
    – General Wear and Tear: Over years, concrete naturally deteriorates due to environmental factors, resulting in the formation of cracks.
    – Thermal Expansion and Contraction: Exposure to repeated cycles of heating and cooling causes concrete to expand and contract, leading to cracks over time.
  • Soil Related Problems
    – Low Compaction and Consolidation: Inadequately compacted soil beneath the foundation can shift, leading to structural instability.
    – Erosion: Water erosion can wash away the soil supporting the foundation, causing it to settle unevenly and crack.
    – Freeze/Thaw Cycles: Water in the soil can freeze and expand during cold weather, then thaw and contract in warmer conditions. This cycle exerts pressure on the foundation, causing it to crack.

How do I Stop my Basement from Leaking?

There are many methods to mitigate basement leaks. The construction of the basement and environmental factors have to be considered when choosing the right products and procedures, and it is always advised to consult a professional in the process.

One solution that has been successfully used for over thirty years is the SealBoss Leak Sealing Foam injection system. This system seals leaking basement cracks and cold joints by injecting a foam that expands to fill and seal the gaps, creating a watertight barrier. This method is effective, long-lasting, and cost-efficient, making it a popular choice for homeowners and contractors alike.

Leaky Basement Repair – Joint and Void Filling Injection

Scope

A homeowner faced persistent basement leakage through cold joints where the wall meets the floor.

Previous repair attempts by a contractor using crystalline products and epoxy coatings had failed, resulting in water pooling on the floor after heavy rains.

In search of a permanent solution, the homeowner sought to prevent further water intrusion into the basement.

Leaky Basement Repair – Detail

A SealBoss technical representative was called to provide expertise on sealing the basement leaks.

Upon careful examination of the job site, it was discovered that the basement floor was approximately 8 inches thick and was poured slightly deeper towards the walls. The source of the leakage was identified as the cold joint between the wall and the poured slab.

Repair System

SealBoss 1510 Water Stop Foam was chosen as the preferred leak sealing injection product to provide a permanent solution. The product would be injected through SealBoss injection packers using the SealBoss P2002 injection machine, a compact, lightweight, and quiet pump ideal for this application.

Procedure

1. Drilling the Slab

  • The slab was drilled with half-inch holes spaced one foot apart, parallel to the wall, and ten inches from the wall.
  • The holes were drilled at a 90-degree angle and full depth into the slab.
  • After drilling each hole, the presence of heavy substrate saturation along the wall was confirmed by water filling the hole, indicating a void beneath the slab that needed to be filled with foam during the injection process.

     

2. Setting the Packers

    • Once all the holes were drilled, packers were placed at half depth and only hand-tightened for easy removal during injection.
    • The injection process began on the side closest to the crawl space’s stub foundation wall.
    • The first packer was loosened, placed at full depth, and retightened, while the next packer in line was removed to allow for a path of less resistance for any displaced water or soil to escape from below and provided visibility for material travel.

 

3. Injection Process:

    • Each packer was injected until catalyzed foam was observed coming out of the adjacent hole.
    • The packer was reinjected a second or third time until refusal or sufficient pressure buildup.

Additional Tips for Homeowners and Contractors

  • Regular Inspection:
    Periodically inspect basements, especially after heavy rains, to detect early signs of leakage.
  • Proper Drainage:
    Ensure proper exterior drainage systems, such as gutters and downspouts, are in place to divert water away from the foundation.
  • Professional Consultation:
    Consult with experienced professionals for thorough assessments and tailored solutions for basement waterproofing.

By following these steps and employing advanced sealing techniques, homeowners and contractors can effectively address and prevent basement leakage, ensuring a dry and secure living space.
