In new construction projects, establishing a solid foundation for footings and slabs is crucial, especially in challenging soil conditions. Polyurethane foam offers a groundbreaking approach to improving soil stability, a key factor in the longevity and safety of new structures.

Cost-Effective and Durable

In new construction, utilizing polyurethane foam for soil stabilization beneath new footings and slabs presents a more economical and efficient approach compared to the conventional practice of excavating and replacing unstable soil. This method not only reduces costs but also greatly enhances the structural integrity of the foundation.

Effective in Waterlogged Conditions

One of the standout features of polyurethane foam is its efficiency in waterlogged or saturated soil conditions. The foam's ability to displace water ensures a stable base, even in areas with high water tables. This characteristic is particularly beneficial for constructions in challenging terrains, where water presence can complicate traditional building methods.

Supporting New Footings and Slabs with Polyurethane

The application of polyurethane foam underneath new footings and slabs represents a significant advancement in construction technology, offering a more efficient, cost-effective, and reliable method for building stable foundations.

As construction excavation projects continue to push the boundaries of complexity, innovative solutions are needed to ensure safety and stability. Polyurethane foam has emerged as an indispensable tool for these unique challenges. With a dual capability to stabilize soil and complement traditional retaining methods like sheet piling or secant walls, polyurethane foam provides robust support precisely when and where it is most needed. Whether plugging gaps to prevent infiltration, enhancing structural support, or sealing out soil in deep foundation pits, this versatile material enables advanced excavations that would otherwise be extremely risky if not impossible.

Support for Traditional Excavation Methods

Polyurethane foam serves the important dual role of both stabilizing soil and supporting traditional methods in complex excavation projects. Used alongside methods like sheet piling and secant piling, the foam creates an impermeable curtain wall injection that seals out the soil. This barrier is crucial for maintaining the stability of surrounding structures.

An Indispensable Modern Tool 

The versatile applications of polyurethane foam demonstrate its indispensability in modern construction. Its ability to adapt to challenging excavation scenarios and bolster conventional techniques makes the foam a critical component in ensuring safe and successful projects.

Excavating near existing structures, particularly in zero lot line scenarios like building additions, poses unique challenges. Traditional methods like sheet piling, while effective, can cause issues such as adjacent structure disruption, soil settlement, and excessive noise, making them less ideal in dense, urban environments.

Polyurethane Grout Walls

The use of polyurethane grout walls, composed of interlocking columns, offers a more suitable solution. This method involves injecting a single component, like AP Soil 600, into non-cohesive soil, creating a stable barrier that supports the excavation site without affecting the adjacent structure.

The Advantages of Polyurethane in Non-Cohesive Soils 

In non-cohesive, loose soils, polyurethane grout walls provide several benefits:

1. Reduced Structural Impact: They minimize the risk of damaging nearby structures.
2. Lower Noise Levels Compared to Sheet Piling: The installation of polyurethane grout walls is significantly quieter than the installation of sheet piles.
3. Soil Stability: Polyurethane enhances soil stability, ensuring safety during and after excavation.

This approach is not suitable for more cohesive soils in which the installation of grout columns is not possible, emphasizing the need for careful soil assessment beforehand. This installation of grout walls to stabilize adjacent structures during excavation is a more precise and less invasive alternative to traditional methods.

Road widening projects, essential for improving traffic flow and infrastructure, traditionally involve digging up and replacing unstable soil. This method, however, poses risks to existing roads and is both costly and time-consuming. The use of polyurethane foam to stabilize existing soil is often more efficient and effective.

The Use of Polyurethane Foam 

In non-cohesive soils, which are loose and permeable, a single-component material like AP Fill 700 is most effective for ground permeation. For cohesive soils like clay, a dual-component material such as AP Lift 475 is more suitable for ground compaction. These materials are injected in a grid pattern to stabilize the soil beneath the road.

Advantages Over Traditional Methods 

This new approach offers significant benefits:

1. Minimized Risk to Adjacent Structures: Unlike traditional methods, polyurethane foam injection does not destabilize adjacent areas.
2. Cost-Effectiveness: The process reduces both material and labor costs.
3. Time Efficiency: Foam injection is faster, accelerating project completion.

The use of polyurethane foam in road widening not only enhances efficiency but also maintains the integrity of adjacent structures, marking a significant advancement in construction technology.

Ground stabilization extends beyond soil to include rock and gravel, crucial for various construction and infrastructure projects. Polyurethane foam, with its expansive and adhesive properties, is an extremely effective solution in these challenging environments.

Case Study: Gravel Wall Stabilization

A collapsing old brick retaining wall necessitated urgent stabilization measures. The challenge was to remove a portion of the wall without causing the loose gravel foundation under a temporary concrete retaining wall to run out. The contractor chose AP Fill 720, a polyurethane resin, for its ability to permeate and lock the gravel in place, achieving high compressive strength. Approximately 50 gallons of AP Fill 720 were used, with injection probes placed strategically to ensure thorough coverage. The process was efficient, taking just one day with a small crew, and was a complete success, allowing for the safe removal of the brick and completion of the project with minimal costs.

Case Study: Railroad Ballast Rock Stabilization

AP Lift 475, a two-component polyurethane foam, was utilized for railroad ballast rock repair and stabilization. This resin was applied to loose bulk ballast stones on railway tracks, increasing their rigidity and stiffness. It served as a weather-resistant solution, reducing vibrations and providing a buffer zone. The application of AP Lift 475 on ballast stones created a polyurethane-stabilized ballast with superior mechanical properties compared to traditional methods.

Beyond Soil: Rock and Gravel Stabilization

These cases demonstrate the versatility and effectiveness of polyurethane foam in stabilizing not just soil, but also rock and gravel, underscoring its utility in a wide range of geotechnical challenges.
