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.

Void Filling in Mayville, WI

Voids beneath concrete slabs, foundations, and driveways can cause settlement, cracking, and structural instability over time. These empty spaces form due to soil erosion, improper soil compaction, underground plumbing leaks, or natural sinkholes. Without proper filling, voids can compromise your property’s stability, leading to foundation failure, uneven concrete, and costly repairs.

At Mayville Foundation Repair, we provide expert Void Filling services in Mayville, WI, using advanced polyurethane foam injection and grout filling techniques to stabilize structures, fill voids, and prevent further settlement.

How Void Filling Works

Void filling is a preventative and corrective process used to restore the support beneath foundations, slabs, driveways, and patios. Our method involves identifying voids, selecting the appropriate filling material, and injecting it into the empty spaces for long-lasting stabilization.

Inspection and Diagnosis

Our team conducts a thorough assessment to determine:

  • Size and depth of voids beneath the foundation or slab.
  • The cause of void formation (e.g., soil erosion, poor compaction, underground water leaks).
  • Signs of settlement, uneven surfaces, or cracking.
  • The best void-filling material for stabilization.

Benefits of Void Filling

1. Prevents Foundation & Concrete Settlement

  • Strengthens underlying soil to prevent further movement.
  • Restores stability to foundations, driveways, and walkways.

2. Stops Soil Erosion & Washout

  • Seals voids caused by water infiltration.
  • Prevents future erosion by stabilizing loose soil.

3. Cost-Effective Alternative to Slab Replacement

  • Avoids the expense of replacing sunken concrete.
  • Repairs voids quickly and efficiently without excavation.

4. Eco-Friendly & Non-Disruptive Process

  • Uses environmentally safe materials that don’t degrade over time.
  • Minimal impact on landscaping, driveways, or property structures.

5. Improves Structural Integrity

  • Supports heavy loads and restores the foundation’s original strength.
  • Prevents further cracking, tilting, or shifting of structures.

FAQs About Void Filling

1. What causes voids under foundations and concrete slabs?

Voids form due to:

  • Soil erosion and washout from poor drainage.
  • Expansive soil shrinkage in dry conditions.

  • Underground water leaks causing soil displacement.
  • Small voids (sidewalks, patios): 1–2 hours.
  • Moderate foundation voids: 1–2 days.
  • Extensive void stabilization: 2–5 days.

Yes! Polyurethane foam is lightweight, waterproof, and long-lasting, while grout filling can be heavier and may settle over time.
