I had them come out to repair my parent's foundation. They got it done in a couple of days, and did great work. They were very professional and responded quickly to all their questions and concerns. They also have the option to get concrete work done, so they got their entrance sidewalk leveled out as well. They are amazing. I would highly recommend.

How Void Filling Works

Void filling is the process of injecting specialized materials beneath a concrete slab or foundation to fill empty spaces, compact the soil, and restore structural support. Our team uses high-density polyurethane foam and grout injection methods to provide a fast, durable, and cost-effective solution for void-related issues.

Common Causes of Underground Voids

Several factors contribute to void formation and soil instability, including:

  • Soil Erosion & Washout – Water runoff can wash away soil beneath driveways, sidewalks, and foundations.
  • Improper Soil Compaction – Loose, uncompacted soil settles over time, creating voids under structures.
  • Leaking Pipes & Drainage IssuesPlumbing leaks weaken the soil, leading to subsurface voids.
  • Decay of Organic Materials – Decomposing tree roots or buried debris leave behind empty spaces.
  • Freeze-Thaw Cycles – Expanding and contracting soil creates pockets of air and unstable ground.
