Everything You Need to Know About Concrete Lifting Foam
Have you noticed uneven concrete slabs on driveways, sidewalks, or pool decks? Concrete sinking is a common problem, but concrete lifting foam provides a quick and lasting solution. Learn how PolyPier’s polyurethane foam works and why it’s the top choice for contractors.
What is Concrete Lifting Foam?
Concrete lifting foam, such as PolyPier by ECP, is a high-density polyurethane foam that expands when injected beneath sinking concrete. This method, often referred to as polyjacking, restores the slab to its original position by filling voids and stabilizing the surrounding soil.
The process involves injecting a two-part liquid resin beneath the concrete through small drilled holes. As the resin and catalyst mix, a chemical reaction creates an expanding foam that lifts the slab, fills voids, and compacts the soil.

Why Contractors Choose PolyPier Foam
PolyPier is engineered specifically for contractors and foundation repair professionals who need reliable, high-performance concrete lifting solutions. Here’s why:
- Precision Lifting – Contractors can lift slabs within 1/10 of an inch of the desired height.
- Permanent Solution – Unlike mudjacking, polyurethane foam is waterproof, resistant to shrinkage, and will not break down over time.
- Minimal Disruption – Small, 5/8-inch injection holes mean less noticeable repairs and faster job completion.
- Fast Curing Time – Foam hardens within 15 minutes, allowing the slab to be used almost immediately.
- Hydrophobic Options – PolyPier offers foams designed for wet conditions, ensuring reliable lifting even in waterlogged areas.
Types of Concrete Lifting Foam Offered by PolyPier
Polyurethane foam isn’t a one-size-fits-all solution. PolyPier provides multiple foam options to fit different project needs:
- Density Range (2.0 to 4.8 lb/ft³) – Lighter foams for small slabs, denser foams for heavier loads.
- Reactivity Speed – Fast-reactivity foams for precision lifting; slow-reactivity foams for void filling and stabilization.
- Hydrophobic vs. Standard Foams – Hydrophobic foams for water-prone areas and standard foams for dry locations.
