Pressure grouting, also known as permeation grouting, stabilizes and strengthens weak or loose soil. This process involves injecting a fluid grout mixture under pressure into the ground. As a result, the grout fills voids, cracks, and spaces between soil particles. While cement grout is often associated with pressure grouting, polyurethane grout offers several advantages.

Understanding the Pressure Grouting Process 

The grout used in this process is typically a low-viscosity, flowable mixture. This allows it to penetrate and fill the void spaces effectively. The injection starts at the lowest elevation, allowing the grout to set before moving to higher elevations. Consequently, this compacts the soil layer by layer.

Essential Tools

Specialized equipment is crucial for effective pressure grouting. For instance, operators use grout pumps, injection pipes, and packers to control the pressure and flow of the grout mixture. This ensures that the grout reaches the targeted areas effectively.

Polyurethane: An Alternative to Cement Grout 

While cement grout is a common choice for pressure grouting, polyurethane grout offers several advantages. Polyurethane is more lightweight than cement, making it less likely to sink after curing. Additionally, polyurethane resists erosion, ensuring long-lasting stability. Furthermore, polyurethane cures faster than cement grout, allowing for quicker project completion.

The Bottom Line

In summary, pressure grouting with polyurethane provides a versatile and effective solution for soil stabilization. While cement grout is often associated with this technique, polyurethane offers several advantages, including lighter weight, reduced erosion susceptibility, and faster curing times. Low-viscosity polyurethane grout under pressure fills voids, consolidates loose soils, and strengthens foundations. With the right equipment and expertise, this method delivers long-lasting solutions for various soil-related challenges.

Deep Lock® is an innovative process developed by Alchatek that utilizes high-quality structural polymers to address deep soil issues. This powerful, painless, and rapid solution stabilizes soil at all levels, ensuring long-lasting results with minimal disruption to the property. This article profiles the two main types of Deep Lock® soil stabilization work and the specific situations in which each type is most effective.

Jobs Requiring One Component Grouts (AP Fill 700 and AP Fill 720)

One-component grouts, such as AP Fill 700 and AP Fill 720, are used for permeation grouting. Permeation grouting involves injecting a low-viscosity grout to saturate loose soil and, upon curing, create a solid, stable mass. This type of Deep Lock® work is ideal for the following situations:

• Loose Soil: When dealing with loose, unstable soil, permeation grouting can effectively bind the soil particles together, creating a stronger foundation.
  
  
• Curtain Walls: One component grouts are often used to create subsurface barriers, or curtain walls, to prevent water infiltration or contain contaminants.
  
  
• Zero-Point Excavation: In cases where excavation is not feasible or desirable, permeation grouting can be used to stabilize the soil without disturbing the surface.

Jobs Requiring Two Component Structural Polymers (AP Lift 430, AP Lift 440, and AP Lift 475)

Two-component structural polymers, like AP Lift 430, AP Lift 440, and AP Lift 475, are used for compaction grouting. Compaction grouting involves injecting a highly viscous grout under pressure to compact and displace the surrounding soil. This type of Deep Lock® work is best suited for the following situations:

• Hard Clay Soils: Two-component structural polymers are effective in densifying and strengthening hard clay soils, which can be challenging to treat with other methods.
• Non-Sand/Silt Mix: When the soil composition is not primarily sand or silt, compaction grouting with two component polymers is often the most effective solution.
• Lifting Involved: If lifting of the structure or surface is desired, two component structural polymers are the ideal choice. These polymers expand after injection, providing controlled lifting force.

Two-component structural polymers offer more versatility than one-component grouts, as they can address a wider range of soil types and provide the added benefit of controlled lifting.

A Versatile Process for Soil Stabilization Work

The Deep Lock® process, with its range of high-quality structural polymers, provides a powerful and efficient solution for addressing deep soil issues. By understanding the specific characteristics of one-component grouts and two-component structural polymers, contractors can select the most appropriate approach for each unique situation. Whether dealing with loose soil, hard clay, or the need for controlled lifting, Deep Lock® has the tools and expertise to deliver rapid, long-lasting results with minimal disruption to the property.

While Alchatek's Deep Lock® process is primarily used on deep soil stabilization jobs, there are specific situations in which deep soil stabilization may be needed to reinforce soil on slab lifting jobs. In cases where slabs are bearing heavy loads, have significantly loose soil underneath, or are located in areas where access is limited, incorporating the Deep Lock® process can help address the underlying soil stability issues. With the addition of the Deep Lock® soil stabilization process, contractors can achieve effective, minimally invasive slab lifting results while simultaneously improving the long-term stability of the foundation.

Slab Lifting for Heavy-Duty Environments

The Deep Lock® process is particularly well-suited for slabs that regularly bear heavy loads, such as:

• Factory floors
• Forklift ramps
• Loading areas
• Fire stations
• Airport runways
• Launchpads

In these high-traffic, heavy-duty environments, soil erosion, poor compaction, and biological decay can lead to slab settling and instability over time. Traditional methods of soil stabilization often fail to address deeper soil issues and can require extensive excavation, heavy equipment, and prolonged downtime.

Deep Lock®, on the other hand, gets to the root of the problem by stabilizing the soil at all levels beneath the slab. The process involves thorough site evaluation, saw cutting of joints if necessary, and the strategic injection of AP Lift structural polymers through small holes drilled in the slab. The expansive properties of the foam fill voids, compact loose soil, and lift the slab back to its original level position.

Soil Stabilization and Slab Lifting for Loose Soil Conditions

This process is also ideal for slabs with significantly loose soil underneath, where erosion or poor compaction has created unstable conditions. By permeating and densifying the soil with AP Lift polymers, contractors using this Deep Lock® process create a strong, stable substrate that can support the slab for decades to come.

Minimally Invasive Slab Lifting for Sensitive or Inaccessible Areas

Another key advantage of applying the Deep Lock® process is the ability to address slab issues in sensitive or inaccessible areas, such as in historical buildings where drilling from the inside is not possible. Because the process involves minimal drilling and can be performed entirely from the exterior, it offers a non-invasive solution for preserving and rehabilitating delicate structures.

Deep Soil Stabilization on Slab Lifting Jobs

Alchatek's Deep Lock® process provides a comprehensive solution for slab lifting and soil stabilization, with powerful results, painless procedures, and rapid return to service. For any slab that regularly bears heavy loads, has significantly loose soil underneath, or requires a minimally invasive approach, Deep Lock® offers a cutting-edge alternative to traditional repair methods. In addition, most Alchatek polymers are NSF-certified for contact with potable water. This approval verifies that the product complies with the strict environmental regulations established by the Safe Drinking Water Act (SDWA).

In Cape Canaveral, Florida, a heavily loaded slap stand structure was planned for construction along a transfer aisle in the Vehicle Assembly Building (VAB). This slap stand would be critical in servicing the proposed Space Launch System vehicle (SLS). However, the project faced a significant challenge when it was discovered that the near-surface subsoils consisted of loose fill materials susceptible to further densification and volume loss due to vibrations and water infiltration. With the slap stand tentatively designed to bear directly upon the ground-level floor slab of the VAB, the degree of subsoil support beneath the floor slab section became a critical concern.

Powerful Polymers

To address this issue, the geotechnical engineer of record recommended a ground improvement solution using permeation grout. Helicon, a leading soil stabilization contractor, worked alongside the geotechnical design team to develop a permeation grout program that would meet the building code load criteria. AP Soil 600, a high-strength, hydro-insensitive structural polyurethane foam, was selected as the ideal product for this project due to its exceptional ability to support heavy structures.

Painless Procedure

Helicon’s technicians installed permeation grout injection pipes on a center-to-center spacing of approximately 2 feet across each of the slap stand areas. The injection points were driven to a depth of at least 5 feet below the floor slab grade. Grout was injected at a relatively low pressure (less than 50 psi), and grout needles were slowly withdrawn during pumping to ensure a uniform distribution of grout to about 3 feet below the bottom of the slab level. The amount of grout used was carefully controlled, with less than 15 gallons per foot per injection point.

Rapid Result

The permeation grout project was a resounding success, effectively improving the load-bearing capacity of the existing soils at the site. The precise application of AP Soil 600 ensured that the slap stand structure would have a stable and reliable foundation, allowing for the safe and efficient servicing of the Space Launch System vehicle. Thanks to Helicon’s expertise and the power AP Soil 600, this piece of critical infrastructure in Cape Canaveral was reinforced and readied for countless future space exploration missions.
