Foundation Repair

Your Partner in Long-Lasting Slab Lifting Solutions

Green Line Services provides expert foundation repair services by injecting polyurethane foam into the ground below. Our innovative approach ensures a durable and lasting fix for your foundation issues.



Causes of Foundation Issues

Concrete is a popular material for slab foundations due to its durability and long lifespan. However, while the concrete itself is strong, the soil beneath it may not be. Over time, gaps in the soil can grow and multiply, leading to settling foundations.

Several factors contribute to this phenomenon:

  • Erosion: Water penetration breaks down the soil, creating voids.
  • Poor Compaction: Inadequate soil compaction can lead to subsurface weakness.
  • Biological Decay: Decomposition of organic material in the soil can create gaps.

Without proper support, the heavy load of a building or house can cause the slab foundation to settle unevenly or even collapse. Uneven concrete creates an unstable foundation, tilting the structure above it. This is where concrete lifting comes in.

Concrete Raising as a Solution

For uneven or sinking concrete, concrete leveling is the answer. Green Line Services prefers injecting polyurethane foam into the soil below.

Benefits of Polyurethane Foam

  • Durability: Polyurethane foam is incredibly strong, supporting up to 14,000 lbs./sq. ft.
  • Effective Gap Filling: The foam permeates the soil, filling gaps and hardening quickly.
  • Waterproof: Polylifting is resistant to water, preventing future erosion.
  • Cost-Effective: This method is more affordable than traditional alternatives.
  • Environmentally Friendly: Safe for the environment and even safe for contact with drinking water.
  • Quick Installation: No heavy equipment or excavation required, with the foundation ready for use just 15 minutes after installation.
