Concrete Lifting

Why Lift With Foam?

Closed cell spray foam insulation is used for concrete lifting because of its physical properties that make it ideal for structural support and stability.

1. High Compressive Strength

• Closed cell foam is rigid and dense, with compressive strengths often ranging from 50 to 100 psi or more.

• This is critical for lifting and holding up heavy concrete slabs without deforming or collapsing.

2. Low Water Absorption

• Closed cell foam is impermeable to water due to its tightly packed cellular structure.

• This is important because water in the soil is often the cause of concrete settling. The foam won’t absorb moisture or break down over time.

3. Controlled Expansion

• The foam expands upon injection, lifting the slab gradually and evenly.

• Contractors can control the lift precisely by adjusting the amount and location of foam injected.

4. Lightweight

• Compared to traditional mudjacking materials (sand, cement, etc.), closed cell foam is extremely lightweight, putting less stress on the soil below and reducing the chance of future settling.

5. Durability

• Closed cell foam cures to a solid, rigid material that is resistant to pests, moisture, and decay.

• It provides a long-lasting solution that doesn’t deteriorate easily over time.

6. Fast Curing Time

• It sets and hardens within minutes, allowing the concrete surface to be used almost immediately after the repair.
