Soil Consolidation Waterproofing Injection

Soil Consolidation & Waterproofing Injection

Soil Consolidation and Waterproofing Injection with Polyurethane Grout

Soil consolidation is a process often employed for soil injection treatment in mining and tunneling projects, but its applications extend beyond these large-scale soil treatment scenarios. One method for achieving soil consolidation, stabilization, and waterproofing involves the use of injectable polyurethane grouts.

Polyurethane grout injection is particularly useful in cases where water migration must be halted and soil shifting needs to be prevented. In this specific jobsite application, we demonstrate the process of using SB FlexGel, a hydrophilic polyurethane injection gel, along with steel injection needles to halt water ingress into a structure through pipe penetrations.

In this specific jobsite application, we demonstrate the process of using SB FlexGel, a hydrophilic polyurethane injection gel, along with steel injection needles to halt water ingress into a structure through pipe penetrations.

Upon injection, FlexGel is a low-viscosity liquid, allowing it to easily migrate through voids, fissures, and cavities in rock structures and loose ground. As it cures, it forms an impermeable bond that consolidates the soil, stabilizes the ground, and creates a watertight seal between the pipe, soil, and structure — This dual function addresses both the soil consolidation and waterproofing aspects of the repair.

As another option, hydrophobic polyurethane grouts and foam grouts can also be employed for this type of application, offering alternative solutions depending on the specific conditions and requirements of the project. These materials can effectively seal off leaks and reinforce the surrounding structure, ensuring long-lasting protection against water infiltration.

Polyurethane injection resins are known for their strong adhesion to rock and soil particulates, and they remain firm and rigid after the expansion process is complete. These properties make polyurethane-based injection products ideal for a wide range of soil waterproofing, consolidation, and stabilization needs.

In this application, Steel Injection Needles are used to deliver the polyurethane grout into the soil at predetermined depths. These needles serve a similar purpose to the more complex and sophisticated Grout Injection Lances often used in large-scale projects. By employing this technique, structures can be protected from water ingress, soil can be stabilized, and long-term durability can be ensured.

Polyurethane Gel Injection for Sealing Pipe Penetration Leaks at a Nebraska Natural Gas Plant

A natural gas plant in Nebraska, responsible for pumping methane gas, experienced persistent water intrusion through multiple pipe penetrations. Previous attempts to patch these leaks from the inside of the structure (negative side) proved unsuccessful. Additionally, water infiltration was observed at the floor-to-wall cold joint.

Soil Consolidation Repair Procedure

Given the easy exterior access to the affected areas, the proposed solution involved soil consolidation and waterproofing injection around the gas pipe from the outside of the structure.

This technique employed SealBoss FlexGel and steel injection needles or lances. It aimed to create a comprehensive solution by waterproofing the soil surrounding the pipe and sealing any water-bearing voids, cracks, and fissures within and around the structure where the pipe penetration occurred. The injection pressure facilitated a secure seal between the pipe and any annular gap between the pipe and the surrounding concrete.

Performing the repair from the exterior minimized further structural damage to the concrete, as it eliminated the need for drilling additional holes and grid patterns.

These steps are typically required when executing soil and curtain injections from the negative side (inside) of a structure.

SealBoss FlexGel LV is a NSF-certified, low-viscosity, single-component hydrophilic polyurethane gel injection rubber and chemical injection grout. It boasts excellent penetration properties, superior strength, and durability. FlexGel was selected for its low viscosity and slower gel time, which allows the resin to infiltrate the substrate and consolidate and waterproof the soil behind the structure and the area surrounding the gas pipe penetrations.

Although FlexGel can be diluted with up to a 10:1 water-to-resin ratio, it was injected “neat” (undiluted) for this application. Using FlexGel neat is a common and approved practice for smaller-scale projects, as it circumvents the need for complex and costly multi-component injection equipment. Instead, simple single-component injection pumps can be used.

The pipe penetrations were identified on the negative side, marked on the structure’s exterior, and used to determine the injection plan based on the penetration spacing. Large pipe penetrations required a minimum of three injection points for full coverage. For pipes up to 6 inches in diameter, one lance was driven directly above the pipe down to a predetermined depth, based on the location of the penetration.

Steel injection needles or lances were installed using a hammer drill and driven to the desired depth. After positioning the lance, the bolt used to drive it was removed, and the applicator with a valve was installed.

For enhanced control of the injection needle/lance, the contractor fastened two vice grip pliers to the top. This enabled them to easily raise and lower the lances to the desired position.

The SealBoss P2002 high-pressure injection pump was utilized to pump the material through the lances. The quantity of material used per lance was measured using the graduated hopper on the pump.

Each penetration was injected until material refusal was evident, either around the penetration or along the cold joint on the floor.

As the FlexGel reacted and expanded, it displaced air and water, causing bubbles to rise from the negative side of the structure. Throughout the injection process, the FlexGel polymer permeated the wall completely and cured. This demonstrated the effectiveness of the repair technique in sealing the pipe penetrations and mitigating water intrusion.

Quality Control

For leak detection and quality control purposes, the injection areas were flooded and saturated with water both before and after the injection repair. This was done to locate and confirm all leaks prior to the injection and to verify the successful sealing of the affected areas post-injection.

Injection Packer Spacing / Placement

Optimizing Injection Packer Spacing and Placement in Leak-Seal Crack Injection

Injection Packer Spacing

Determining Mechanical Injection Packer Spacing Based on Site Conditions and Product Properties

In the context of leak-seal crack injection, the spacing of mechanical injection packers, also referred to as port spacing, necessitates careful consideration of various site conditions, such as crack width, substrate thickness, water flow, and product properties.

For numerous applications, an initial spacing range of 8 inches (20 cm) to 1 foot (30 cm) on-center is a suitable starting point. However, the presence of hairline cracks calls for tighter spacing, as the limited product dispersion hampers its ability to traverse extensive distances. Consequently, narrower cracks demand closer packer spacing.

Injection Packer Placement

Employing Staggered Injection Packer Placement for Enhanced Crack Intersection and Reduced Concrete Damage

To optimize the efficacy of leak-seal crack injection, contractors should, whenever feasible, employ a staggered injection packer placement strategy.

This entails alternating drill holes to the left and right of the crack and drilling at a 45-degree angle towards the crack, thereby creating a stitch grouting pattern.

Utilizing this technique increases the desired probability of intersecting the crack during drilling and diminishes the likelihood of inducing additional cracking or spalling in the concrete throughout packer installation or the high-pressure injection process.

It is generally advised to initiate the injection process at the lowest point and proceed in an upward direction.

What Causes Unstable Soil? | Slab Lifting – Polyjacking – Permeation Grouting

What Causes Unstable Soil?
Permeation Grouting - Filling - Polyjacking

Unstable soil encompasses earth materials susceptible to shifting, moving, or shrinking due to their composition or environmental and human-induced conditions. Its inherent instability can pose a serious threat to the stability, security, and integrity of infrastructures, leading to the potential damage or degradation of structures such as buildings, bridges, and roads.

Unstable soil may not remain in place without extra treatment, support or shoring. Understanding the root causes of unstable soil is integral in combating its negative impacts. Here are the four primary factors contributing to soil instability:

Poor Soil Compaction

Poor soil compaction is a well known cause of unstable soil and often results in structural damages and sinking structures. Poor soil compaction can be attributed to various factors, primarily centered around soil texture and properties. Certain soils are more susceptible to compaction due to factors like high clay content, excess salt, low pH, and high water content. Construction choices also play a role; improper selection of compaction equipment and materials by contractors can lead to subpar compaction. Certain areas, like soil adjacent to foundations, are more prone to poor compaction as well.

Depending on soil composition and density, permeation grouting and polyjacking may provide solutions to these problems.

Soil Erosion

Erosion is a geological process involving the movement of the earth’s crust due to factors like water flow, wind, and human actions. Erosion, whether caused by wind, water, temperature changes, or human activities, is a process that removes soil or rock from one location and transports it to another. This constant displacement destabilizes the soil, causing undesirable consequences such as landslides, sinkholes, and damaged structures.

For construction projects and any existing structures, unstable soil due to erosion can jeopardize investments and endanger buildings.

Freeze/Thaw Cycles

Freezing and thawing can change the physical structure of soil and lead to increased erosion. The expansion of frozen water trapped in the substrate opens fissures in the soil and rocks to the extend of breaking up even solid structures. Freeze and thaw events create expansion and contraction cycles in the soil and minerals which lead to a continued break down and potential loss of integrity.

Particularly on fine-grained soils prone to freezing and thawing, issues arise due to soil instability. Thawing frost and permafrost, soil with frozen water particles, softens and reduces soil compactness, leading to structural sinking. This poses significant challenges for building and infrastructure development.

Organic Decomposition

Soils containing a high concentration of organic materials are subject to decomposing through chemical processes and microorganisms such as bacteria, fungi, archaea and protists. As organic materials break down, they lose mass and cohesion, which weakens the soil’s overall integrity. The spaces left by decomposed materials can cause the soil to become more porous, reducing its ability to support weight and withstand external pressures. This increased porosity can also lead to changes in water drainage patterns, potentially causing uneven settling and erosion.

The rapid soil transformation and eventual loss of a high percentage of the organic material during decomposition can cause soil volumes to shrink, contributing to instability. In summary, decomposition disrupts the soil’s structure, cohesion, and load-bearing capacity, making it more prone to shifts, settling, and erosion, which collectively contribute to soil instability.

Unstable Soil Solutions

Soil stability is a critical aspect of construction and infrastructure projects. Unstable soil can cause significant damage to structures, such as foundation and wall cracking, and can even lead to collapse.

The SealBoss Void Filling, Polyjacking and Permeation Grouting System may help mitigate these causes of unstable soil.

Soil stability can be restored to soil with adequate polyurethane resin and foam products and structures can be supported and in some circumstances raised.

At SealBoss, we have product solutions for sinking slabs, foundations, seawalls and retaining walls in commercial and residential environments.

Polyurethane resins, foams, and grouts are excellent solutions for stabilizing unstable soil. In this article, we will explore the technical details of using these materials and their benefits.

Polyurethane Resins for Soil Stabilization

Polyurethane resins are synthetic materials that have excellent adhesive properties, making them ideal for stabilizing soil. These resins are injected into the soil in a liquid form, where they expand and harden, filling voids, and stabilizing the soil. Polyurethane resins are typically used to fill voids or stabilize the soil around the foundation, but they can also be used to strengthen slopes and embankments.

One of the significant benefits of using polyurethane resins for soil stabilization is that they are easy to use and can be applied quickly. They are also NSF water contact approved products to prevent harm to the environment. Polyurethane resins can be applied in many conditions, making them a versatile solution for unstable soil stabilization.

Foam Jacking for Soil Stabilization

Foam jacking, also known as polyjacking, is a technique used to stabilize soil by injecting foam into the soil to fill voids and create support to a structure and provide for some lifting, if neccessary . The foam expands and hardens, lifting the soil and filling voids, stabilizing the soil, and correcting many settlement issues.

Foam jacking is an excellent solution for fixing concrete slabs, sidewalks, and driveways that have sunk due to soil instability. The foam jacking process is quick, and there is minimal disruption to the surrounding areas. Foam jacking is also cost-effective compared to other soil stabilization techniques, making it an attractive option for homeowners and contractors.

Permeation Grouting for Soil Stabilization

Permeation grouting is a soil stabilization technique used to strengthen soil by injecting polymer grout into the soil. The grout is injected into the substrate at pressure, filling voids and stabilizing the soil by compaction and adhesion.

Permeation grouting is commonly used to stabilize soil around tunnels, bridges, and buildings. The process is quick, and there is minimal disruption to the surrounding areas. Permeation grouting is also a cost-effective solution for soil stabilization and is an excellent option for large infrastructure projects.

Benefits of Polyurethane Resins, Foams, and Grouts for Soil Stabilization

Polyurethane resins, foams, and grouts are excellent solutions for soil stabilization. Here are some of the benefits of using these materials:

Versatility: Polyurethane resins, foams, and grouts can be used to stabilize different types of soil, including sandy, somewhat clayey, and rocky soils.
Environmentally Safe: Materials are available that have been certified for drinking water contact and are used for projects that require minimal impact on the environment.
Cost-Effective: Polyurethane resins, foams, and grouts are cost-effective solutions for soil stabilization. They require less labor, typically smaller equipment and often less material compared to other techniques, making them ideal for larger and very small infrastructure projects.
Quick Application: These materials can be applied quickly, reducing the amount of downtime and disruption to the surrounding areas.

Polyurethane resins, foams, and grouts have been used in many unstable soil stabilization applications.

Pump Station Infiltration Repair

How to Stop Water Inflow & Infiltration
I & I - Repair

Texas – A Municipal Water District was experiencing heavy groundwater infiltration at the pre-cast cold joints in multiple Lift Stations in a new housing development

After previous attempts to stop an inflow and infiltration water leak using low pressure and mastic waterstop had failed, the Municipal Wastewater District reached out to SealBoss looking for a turn-key system that could withstand the hydrostatic pressures, causing active leaks in a lift pump station and seal them permanently with minimal effort, expense and resources.

Time of repair was a key factor due to the need for special permits, including a confined space permit, and lane closure requirements with traffic control for use of truck mounted equipment.

Municipal Wastewater Pump Station Infiltration Repair

With the recommendation of Chemical Grouting, following previous failures and repair attempts, the Wastewater Conveyance Team was interested in a demo of the system including an on-the-jobsite training. A SealBoss technical representative made the drive down from Kansas City to in order to demonstrate the chemical grouting system and assist the Water & Sewer Utility Provider in the installation and repair.

After arriving at the location, the leak was evaluated and a strategy for injection was formulated.

To initiate the injection plan, the first step was to drill holes in the pit. These holes were spaced approximately 12 to 18 inches apart and positioned 4 inches above the cold joint. They were drilled at a 45-degree angle, extending back into the joint. Subsequently, the holes were flushed using a squirt bottle until clean water was refused, and high-quality mechanical packers were then installed.

Following an in-depth training on the use and cleaning of the very quiet and compact SealBoss P2002-1C Injection Pump and the use of SealBoss 1510 NSF Certified Water Stop Foam, the trainee applicator climbed back in the manhole to run the pump system by himself.

To expedite the foam production process for the active leak repair, SealBoss 15X Catalyst was utilized at a slightly higher percentage than the standard recommendation of 10% volume.

The procedure involved injecting from one end of the main line pipe until resin or foam was visible at the cold joint, and subsequently spraying some water to initiate the reaction.

How to seal unexpected leaks during the injection repair

Sometimes concrete cracks and spalls form during the packer installation or injection process. Drilling holes can occasionally become to wide for the intended packer to fit. For these kinds of situations it is recommended to have Seal Oakum and various sized Injection Packers on hand.

In this specific application, as injection continued around the joint, one of the holes was apparently drilled too close to the joint and subsequently spalled out, causing it to leak significantly.

With a quick dredge of the oakum in catalyzed SealBoss 1510 Water Stop Foam, a bag of Soaked Oakum was sent down into the manhole and held in place by the applicator over the leaking spall. After about two minutes of holding the oakum in place, the leak had stopped.

The area was then injected on either side of the installed oakum to fill any remaining voids and to seal the joint permanently.

All leaks were completely stopped within 90 minutes time. The total time on site amounted to two hours.

Historical Building Repair – PUR Injection

This well over a century old historical apartment building had persistent water intrusion through the masonry rock foundation into the below grade parking garage.

A SealBoss Technician was asked to come out and consult with a local installer in St. Louis, Missouri, to find solutions for the water ingress problem. The majority of the exterior walls where the sill plate sits at or just below grade had shows signs equivalent to years of water intrusion.

The century old stone wall, and the grout holding the natural rocks in place, had become compromised. Water would seep from the soil through the wall causing further decay, unsightly stains and in some areas growth of unsightly algae.

Previous non-permanent and haphazard repairs included cleaning the wall and opening up the face with a grinder then applying a cementitious grout over the whole face of the wall. This attempt of a repair would fail within a year of application.

The approach to a permanent historical building repair was to inject any visible cracks first. One of the areas with heavy water intrusion was a doorway that lead from the parking garage to the stairs leading to the domicile. Here there was a water bearing crack with an active leak overhead as well as a cold joint between the floor and stub wall.

The overhead crack was addressed using 5/8” Plastic Injection Ports as the grout lines would crack and flake when a mechanical packer was tried initially. A zerk tip was added to the injection port and the crack was primed by injecting water through the packer till positive refusal was seen from the crack.

SealBoss 1510 Chemical Injection Grout was then injected under pressure to displace any water in the crack and began to cure and seal the area.

To address the cold joint on the floor in the stairwell, ½” packers were installed on the floor roughly one foot apart and six inches from the wall. It was confirmed that behind the stub wall in the stairwell was substrate and upon install of the Packers, it was found that the floor had only been about a two inch pour.

With the thin floor slab, it was advised to inject through the slab creating a “blanket” of 1510 below the slab since the slab thickness would not allow for the standard 1, 2, 3, 45 Degree Injection Packer Placement Method.

A weep hole was also drilled in the slab to allow for a controlled point where the water and off gas could be directed. Positive refusal of the foam was visible from the cold joint, and once the joint had been sealed, packers were removed and a hydraulic cement patch was installed.

Once all cracks have been addressed, wet areas can be addressed by curtain / bladder injection, where chemical grout is injected behind the wall to create a waterproofing barrier between the soil and the wall on the positive side of the structure.
