Polymer Grout Systems for Irrigation District Canal Sealing

The Challenge of Leaking Canals

The network of irrigation canals that crisscross agricultural regions is vast and complex. Managed by various entities, including the Bureau of Reclamation, this infrastructure spans thousands of miles and is crucial for the delivery of water to farmlands. However, the aging of these canals, combined with natural and mechanical damages, presents a continuous battle against leaks and seepage. Such issues not only lead to water loss but also pose significant risks to the structural integrity of canals, potentially resulting in erosion, sinkholes, and even catastrophic breaches that can have far-reaching impacts on agriculture and nearby communities.

Advanced Solutions for Irrigation District Canal Sealing

Polyurethane Grout Injection

Polyurethane grout injection stands out as a modern solution for addressing irrigation canal leaks. This method involves injecting a liquid polymer, which expands upon contact with moisture, into cracks and voids, thereby creating a durable, watertight seal. The rapid curing time of polyurethane grout minimizes downtime in water delivery, and its flexibility allows the structure to accommodate future movements, significantly reducing the likelihood of recurrent leaks.

Using NSF Drinking Water Contact Certified Polyurethanes

NSF-approved polyurethane grouts are essential in irrigation canal sealing because they meet stringent safety standards by the National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI). This certification ensures these materials are safe for use in environments in contact with potable water, preventing contamination. SealBoss NSF/ANSI/CAN 61 Certified Products undergo rigorous testing to ensure they do not leach harmful contaminants, making them a reliable choice for maintaining the purity of water systems and complying with regulatory requirements for public health and environmental protection.

Addressing Seepage with Curtain and Probe Grouting

In addition to direct crack sealing, addressing pervasive seepage is critical for maintaining the functionality and integrity of irrigation canals. Techniques such as curtain and probe grouting play a crucial role in this context. Curtain grouting involves creating a grout barrier along the canals wall to block water pathways into the soil, while probe grouting with injection lances targets specific seepage paths, allowing for precise application and minimal environmental disturbance.

Steel Injection Lances, tailored for specialty grouting applications, facilitate the delivery of various polymer solutions directly into the soil. Their primary function is to inject these polymers deep into the soil to enhance its properties. By doing so, they significantly increase the soil’s strength, decrease its permeability, and improve its overall stability, making them indispensable tools for polymer leak sealing and soil stabilization efforts.

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

Seawall Repair with Polyurethane Foams
Plural Component vs Single Component Foam

Concrete Solutions Since 1988

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

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.

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.

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

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.

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.

How To Podcast:
Leak Sealing Polyurethane Crack Injection
in Concrete and Shotcrete Structures

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.
