Concrete Void Fill with Foamjacking

Concrete void fill is an essential process that resolves the issue of unwanted spaces or cavities beneath concrete slabs or structures. These voids can lead to instability, water accumulation, and eventual damage to the structure. Midwest Foam Works specializes in using high-density polyurethane foam to effectively fill these voids, ensuring a stable, safe, and long-lasting solution.

Why Choose High-Density Polyurethane Foam for Concrete Void Fill?

High-density polyurethane foam has emerged as a superior choice for void fill applications. Unlike traditional materials like mud or sand, this foam expands upon injection, ensuring a tight and comprehensive fill. Its lightweight nature means it doesn't add significant weight or pressure to the underlying soil, reducing the chances of further soil compaction or displacement.

Additionally, polyurethane foam has a fast curing time. This means areas treated can be put back to their regular use shortly after the procedure. Its moisture-resistant properties prevent water accumulation, reducing risks related to mold growth, soil erosion, or frost heaving.

How It Works


Drill and Inject

Our two-part polyurethane foam is injected through 5/8" holes drilled through your concrete slab. At this point, the polyurethane is a two-part liquid which easily flows and seeks out voids, much like water seeking the path of least resistance.



After 10-15 seconds, the polyurethane mixture starts to expand. This expansion fills any voids, drives out moisture, and compacts the remaining base. Once the area is stabilized, our technician strategically continues to inject polyurethane until your concrete is lifted back to its original postition.



Holes are patched, the work is tidied, and your concrete is ready to drive on within 20 minutes!
