Polyurethane Foam Injection: The Definitive Guide to Concrete Repair and Waterproofing

Polyurethane foam injection for crack repair and soil treatment has revolutionized the field of concrete repair and waterproofing, offering reliable and long-lasting solutions for a wide range of structural problems. This advanced technique effectively seals cracks, stabilizes foundations, and prevents water intrusion, making it a preferred choice among industry professionals. This comprehensive guide will delve into the key aspects of polyurethane foam crack injection, its applications, benefits, processes, and how it compares to other crack repair methods.

Polyurethane Foam Injection Systems and Applications

1. Understanding Polyurethane Foam Crack Injection and soil Injection Treatments

Polyurethane foam crack injection involves injecting a reactive foam into cracks, voids, or joints in concrete structures. The polyurethane resin expands upon contact with water, forming a flexible, closed-cell foam that seals leaks and prevents water from entering the structure. This method is particularly effective for below-grade waterproofing, foundation crack sealing, and repairing structural cracks caused by settlement, shrinkage, or hydrostatic pressure.

2. Key Applications of Polyurethane Grout Injection

Polyurethane foam injection is versatile and suitable for a variety of applications in both residential and commercial settings:

  • Foundation Crack Sealing: Polyurethane injection effectively seals foundation cracks, preventing water infiltration and reinforcing structural integrity. It addresses cracks caused by settlement, shifting, or external water pressure, ensuring a long-lasting repair.
  • Basement Waterproofing Injection: This technique is ideal for waterproofing basements by sealing cracks and joints in foundation walls and floors. Polyurethane foam injection creates a watertight barrier, preventing water seepage and protecting the interior from moisture damage.
  • Curtain Wall Grouting: Curtain wall grouting involves injecting polyurethane foam behind the structure, creating a water barrier on the positive side. This method is highly effective for large-scale waterproofing projects, such as tunnels, retaining walls, and below-grade structures.
  • Bladder Injection Method: In the bladder injection method, foam is injected into voids and gaps behind concrete walls, forming a bladder-like seal that blocks water intrusion. This technique is especially useful in areas with high hydrostatic pressure.
  • Slab Lifting and Stabilization: Polyurethane injection is also used to lift and stabilize uneven slabs. Known as slab jacking, the expanding foam fills voids under the concrete, restoring stability and levelness without the need for extensive excavation.

3. Types of Polyurethane Foam for Crack Injection

Polyurethane foams used in crack injection are categorized based on their properties and applications:

  • Hydrophobic Polyurethane: Hydrophobic foams repel water and are ideal for sealing large cracks and voids. They expand minimally, providing a dense and durable seal without absorbing moisture.
  • Hydrophilic Polyurethane: Hydrophilic foams absorb water and expand significantly upon contact, making them suitable for sealing fine cracks and creating flexible seals in dynamic environments. These foams are particularly useful in curtain wall and bladder injection applications where thorough penetration is required.

4. The Injection Process: Step-by-Step Overview

The polyurethane foam crack injection process is a systematic approach that ensures effective sealing and waterproofing:

  • Surface Preparation: The area around the crack is cleaned to remove debris, dust, and loose particles, ensuring optimal adhesion of the foam.
  • Crack Evaluation and Drilling: The crack is assessed to determine its size, condition, and water activity. Holes are drilled at regular intervals along the crack to allow for the installation of injection packers.
  • Installation of Injection Packers: Packers are inserted into the drilled holes, providing a secure entry point for the foam injection.
  • Injection of Polyurethane Foam: Polyurethane resin is injected through the packers under controlled pressure. The foam expands within the crack, filling all voids and creating a watertight seal.
  • Curing and Final Inspection: The foam begins to cure immediately, expanding to fill the entire crack. A final inspection ensures that the crack is fully sealed and no voids remain.

5. Advantages of Polyurethane Foam Injection

Polyurethane foam injection offers numerous advantages over traditional crack repair methods, making it a preferred choice for professionals:

  • Flexibility and Adaptability: Unlike rigid materials, polyurethane foam remains flexible after curing, allowing it to accommodate minor structural movements without compromising the seal.
  • Water Resistance: Polyurethane’s hydrophobic properties ensure that the foam repels water, maintaining its integrity even in wet conditions.
  • Minimal Disruption: The injection process can be performed from the inside, avoiding the need for extensive excavation or structural modifications.
  • Quick and Efficient: Polyurethane injection is relatively fast, often completed within a few hours, minimizing downtime and disruption.
  • Long-Lasting Solution: The foam creates a permanent seal that resists environmental factors, unlike patches or surface applications that often fail over time.

6. Comparative Analysis: Polyurethane vs. Other Crack Repair Methods

Polyurethane foam injection is often compared to other crack repair methods, such as epoxy injection and hydraulic cement patching:

  • Epoxy Injection: While epoxy is strong and ideal for structural repairs, it lacks the flexibility needed for dynamic environments. Epoxy also requires dry conditions, limiting its effectiveness in actively leaking or wet cracks. Polyurethane, by contrast, excels in both wet and dynamic conditions.
  • Hydraulic Cement Patching: Hydraulic cement requires chiseling out the crack into a vee-notch, which is labor-intensive and often fails over time due to poor adhesion. In contrast, polyurethane fully penetrates the crack and bonds tightly to the surrounding concrete, providing a more reliable and permanent solution.

7. Equipment and Tools for Polyurethane Injection

Successful polyurethane crack injection relies on specialized equipment designed for precise and controlled application:

  • Injection Packers: These are installed in drilled holes along the crack and serve as entry points for the foam. Packers can be mechanical or hammer-in types, depending on the pressure requirements of the injection.
  • Injection Guns and Pumps: High-pressure pumps deliver the polyurethane resin into the cracks. These pumps can be adjusted based on the size and complexity of the crack, ensuring efficient foam distribution.
  • Mixing Systems: Some polyurethane foams require precise mixing of components before injection. Advanced mixing gear maintains correct ratios, enhancing the performance and consistency of the foam.

8. Safety Considerations and Environmental Impact

Handling polyurethane foams requires strict adherence to safety protocols to protect workers and the environment:

  • Protective Gear: Operators must wear gloves, goggles, and respirators to minimize exposure to chemicals during the injection process.
  • Proper Ventilation: Even though high quality foams do not contain VOC`s or solvents, adequate ventilation is necessary to disperse any fumes generated during the injection, especially in enclosed spaces.
  • Eco-Friendly Options: Environmentally friendly polyurethane foams are available, minimizing the impact on the surrounding ecosystem. Responsible disposal of waste materials and adherence to environmental standards contribute to a sustainable injection process.

9. Innovative Uses and Future Developments in Polyurethane Injection

Polyurethane foam injection continues to evolve, finding innovative applications beyond traditional concrete repair:

  • Industrial Applications: Polyurethane is used to stabilize machinery pads, fill voids around pipelines, and reinforce infrastructure in industrial settings, demonstrating its versatility.
  • Geotechnical Solutions: Polyurethane is ideal for stabilizing soil, filling voids, and preventing erosion around underground utilities, aligning with sustainability goals.
  • Ongoing Research: Continuous advancements in polyurethane technology focus on improving performance, reducing curing times, and enhancing environmental sustainability.

10. Cost Analysis and Economic Benefits

Understanding the costs associated with polyurethane injection is essential for making informed decisions:

  • Direct Costs: The direct costs of polyurethane injection include materials, labor, and equipment. While these costs can be higher compared to simpler methods like patching, the long-term benefits in most scenarios outweigh the initial investment.
  • Low Indirect Costs: Polyurethane injection typically requires minimal service interruptions, reducing indirect costs related to downtime and additional repairs.

11. Addressing Common Challenges and FAQs

Below are common questions and concerns related to polyurethane foam injection:

Curtain Injection In Pictures

Curtain / Bladder Injection - Curtain Wall Grouting Method

Water intrusion is a persistent challenge for below-grade concrete structures, where traditional patching and surface sealers often fall short. The failures of these surface-applied remedies—such as patches, liquid sealers, and membrane applications—stem from their inability to address the root causes of leaks. These methods provide only temporary relief, leaving structures vulnerable to recurring hydrostatic pressure and ongoing water damage.

Curtain wall grouting, including advanced techniques like curtain and bladder injections, offers a reliable, long-term solution to these challenges. Unlike surface treatments, these methods work by creating a robust waterproof membrane and water barrier behind the structure. This approach not only seals cracks and cold joints from within but also fortifies the structure against future water intrusion.

By injecting specialized grouts through the structure to form a protective layer on the positive side, curtain injection ensures a comprehensive and lasting seal. Whether applied through stage grouting or other targeted injection methods, this professional approach delivers durable protection, minimizing service interruptions and maximizing cost-effectiveness in the long run.

Curtain / Bladder Injection is the Reliable Way to Waterproof Your Below Grade Concrete Structure Permanently

Why Patches and Liquid Sealers Often Don’t Stand the Test of Time

Experiencing the frustration of failing patches and paint applications on damp, actively leaking, below-grade structures is something many of us can relate to.

These are typically failed attempts to block hydrostatic water intrusion using surface-applied remedies that serve as temporary solutions at best.

Interior patches and membrane applications, while seemingly addressing the problem, often don’t tackle the root cause and rarely provide a lasting waterproofing resolution.

A Professional Approach to Curtain Injection:

Sealing Cracks Permanently and Establishing a Waterproof Membrane and Water Barrier behind the Structure

Water leakage via cold joints, cracks, and other irregularities in concrete can frequently only be effectively and permanently sealed using advanced injection techniques, such as curtain, bladder, and stage grouting injection methods.

The SealBoss Injection Product offers a professional solution to these issues, filling and sealing the cracks from the inside out. This product is injected through the structure, forming a membrane on the structure’s positive side, thus providing a more effective and lasting waterproofing solution.

The Art of Stage Grouting Technique

In complex grouting scenarios, the stage grouting technique is often the favored approach. This process entails a strategic series of injections carried out in a staged manner, utilizing lower volumes of product in each application.

Each stage of this meticulous process is allowed sufficient time to react, allowing the grout to solidify and establish a natural barrier before proceeding with the subsequent stage of grouting. This carefully phased and controlled deployment not only elevates the overall efficacy of the grouting operation but also ensures thorough and consistent coverage along the exterior of the wall.

Comparative Cost Analysis of Injection Grouting Sealing Methods

Understanding the financial impact of various sealing techniques is essential for making cost-effective decisions. Below is a comparison.

Crack Injection

Direct Costs: Moderate for materials and labor, product is injected directly into the cracks, joints, and voids. Low for equipment.
Indirect Costs: Minimal, as the method is fastest and causes little service interruption.

Curtain Grouting

Direct Costs: Higher for materials and labor, product is injected through the structure into the substrate behind, which results in higher material consumption. Packers are set in distinctive patterns. Moderate for equipment.
Indirect Costs: Higher, due to the lengthier process of preparation and product pumping, which can lead to more significant service disruptions.

Restoration Waterproofing

Restoration - Waterproofing

Restoration – Waterproofing with Injection Resins, Gels, and Foams

Restoration waterproofing projects represent a mix of various complex tasks, each with its unique set of challenges. The first crucial step is identifying the root source of the water infiltration, which at times can be a difficult process.

Diagnosis

A correct leak diagnosis might necessitate various steps, such as performing visual inspections of the inside and outside of the structure, examining the surrounding conditions, conducting flood tests, utilizing dye testing, creating mock-ups, and removing paints and finishes. 

Setting Defined Objectives

Before starting a restoration waterproofing project, it is crucial to clarify the goals and expectations for every party involved.

It goes without saying that the primary aim of such a venture typically revolves around halting water intrusion. There are many techniques and products that can be used for this, such as polyurethane injection foams, gels, and resins, as well as acrylate injection gels and even epoxy resins in some circumstances. These methodologies come with their individual costs, levels of site disruption, and project timetables. It is essential that all of these elements are thoroughly considered and presented to the end customer, facilitating an informed decision-making process.

Understanding Water Movement and Migration

It is indispensable to understand some key concepts related to water migration and movement around and within soil,  structures, voids, joints, and cracks.

Water is Not Always Visible

The obvious appearance of a leak in a specific location does not definitively imply that other areas are devoid of water ingress. Water invariably seeks the path of least resistance, typically navigating towards any openings, fissures, and low spots. Upon remediation of these lower areas, the water may find its way to other compromised zones.

Leak Detection Techniques

The leak detection process is further complicated if the repairs are undertaken during a period of relative dryness. Under such circumstances, leak migration might not become evident until the advent of the next rain event. For more controlled testing, it may be advisable to deliberately flood the surrounding area, creating conditions that could induce a leak at the time of inspection and repair. Conducting flood testing before, during, or after the repair work can contribute significantly towards pinpointing any areas where the leak may have migrated. Executing waterproofing repairs amidst active leaking can effectively help identify and repair leak migration issues.  

Restoration Waterproofing Products 

Polymer injection foams, resins and gels serve as viable solutions in restoration waterproofing. Their superior qualities make them ideal for sealing leaks, even in wet environments. Polyurethane foams are adept at sealing large leakages, both in volume and speed, expanding upon contact with water to block infiltrations effectively. On the other hand, super low viscosity resins and gels ensure a long-lasting solution for smaller, more intricate leaks, seeping into hairline cracks and curing to provide a waterproof seal. Implementing curtain injection behind a structure can effectively generate a waterproof, membrane-like barrier, thus sealing wet and damp spots within concrete and masonry structures.

At times, epoxy resins may be required to restore structural integrity, even in wet or damp conditions. For an in-depth comparison between epoxy and polyurethane injection, please refer to the detailed information provided here.

In Conclusion

Remedial restoration waterproofing is often an iterative, exploratory process that might necessitate adjustments along the way. Setting realistic expectations, keeping open lines of communication among all involved parties, and maintaining a keen eye for detail are important to the efficient and successful execution of a waterproofing process.

A well-executed waterproofing restoration can add years to the lifespan of a structure, safeguarding it against potential damage and preserving its aesthetic and functional value.

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 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.

Cold Joints in Concrete Structures and the Polyurethane Polymer Solution

Introduction

Concrete is a versatile and durable construction material, but like all materials, it has its weaknesses. One such weaknesses is the formation of cold joints. Understanding what cold joints are and how to address them is crucial for anyone involved in the construction or repair of concrete structures.

What are Cold Joints?

A cold joint forms when newly mixed concrete is laid adjacent to or over concrete that’s already started to harden. This situation can manifest due to several factors, including disruptions during pouring or delays in the mixing and transportation of the concrete. This leads to the formation of a distinct boundary, a zone lacking cohesion, where the previously set and fresh concrete converge. Such a boundary weakens the overall structural strength of the concrete, rendering it susceptible to water infiltration and potential leakage. Over time, the presence of cold joints can reduce the overall lifespan of the concrete structure.

The Polyurethane Polymer Foam Injection Solution – Injecting cold joints with polyurethane polymers has emerged as an effective solution to address the issues of water migration and leakage.

Injection Process

Using specialized equipment, the polyurethane polymer is injected into the cold joint. The polymer fills the voids and gaps, creating a permanent seal. The polymer acts as a barrier, preventing water from seeping through the cold joint. The injected polymer reinforces the cold joint, reducing the risk of corrosion, cracks or breaks. With the cold joint addressed, the overall lifespan of the concrete structure can be significantly extended.

Addressing Cold Joints with the SealBoss Injection System – Comprehensive Solution to Moisture and Active Leaks

Cold Joints are common locations where moisture and active leaks are frequently observed. Whether stemming from a flawed waterproofing system or its total absence, we offer a comprehensive solution to address the leak and stop any water intrusion.

Our SealBoss Regional Sales Manager was on-site in Kansas City to train and assist with the injection of below grade cold joints that had begun to actively leak due to failures in the pre-existing waterproofing system.

Both vertical and horizontal cold joints were injected with various levels of leak activity.  The contractor drilled the injection holes and installed 1/2″ SealBoss mechanical packers for a tight fit. Based on the conditions the 45 angle drill degree method was used as well a direct into the joint placement was chosen.

The applicator then injected SealBoss 1510 using the P2002 high-pressure single component injection pump. Due to the relatively low temperatures of the substrate the product was catalyzed with approximately 15% of SealBoss 15X highfoamer accelerator. All active leaks were successfully stopped and the Cold Joints sealed.
