Frequently Asked Questions

General FAQ's

Is polyurethane safe for my home and yard?

Once cured, polyurethane foam is inert and environmentally stable. It does not leach harmful chemicals into soil or groundwater. 

Will there be heavy equipment in my yard?

No heavy demolition equipment is required. Our tools are compact and minimize disruption to your property. 

Why should I fix uneven concrete?

Uneven concrete creates trip hazards, drainage issues, pooling water, reduced curb appeal, and liability concerns. 

Do you offer free estimates?

Yes. Mission First Concrete Leveling proudly offers FREE estimates throughout Eastern and Northern Wisconsin.

Concrete Caulking FAQ's

Why is concrete caulking important?

Concrete caulking seals joints and cracks to prevent water intrusion, reducing soil washout and future settling. 

Does caulking help prevent concrete damage?

Yes. Sealing joints keeps moisture out, reducing freeze-thaw damage and premature cracking.

Concrete Leveling Questions 

What is polyurethane concrete leveling?

Polyurethane concrete leveling is a modern repair method used to lift and stabilize sunken concrete slabs without tearing them out. We inject high-density expanding foam beneath the slab, which fills empty space and gently raises the concrete back into place. This process restores safety and adds value without the mess and cost of replacement. 

How does concrete leveling work?

We drill small access holes in the slab, inject structural polyurethane foam beneath the concrete, and allow the expanding foam to fill voids and lift the slab to proper height. Once level, we seal the holes and clean the area. Most projects are completed in just a few hours. 

How long does concrete leveling take?

Most projects are completed in a single visit. The foam cures quickly, and surfaces are typically ready for use within 15–30 minutes after completion. 

Is concrete leveling cheaper than replacement?

In most cases, polyurethane concrete leveling costs significantly less than full concrete replacement. Replacement requires demolition, hauling, forming, pouring, and curing time, which increases costs.

What types of concrete do you lift?

We lift and stabilize driveways, sidewalks, patios, pool decks, garage floors, basement slabs, warehouse floors, and concrete steps.

How long does polyurethane foam last?

High-density polyurethane foam is engineered for long-term stability. It is water-resistant and designed to maintain structural support for years.

FAQ's about Void Fill

What is void fill and why is it important?

Void fill is the process of filling empty spaces beneath concrete slabs. Soil erosion, poor compaction, or water washout can create gaps that lead to settling and cracking. Filling these voids stabilizes the base and prevents further movement.

What causes concrete to sink?

Common causes include soil erosion, poor soil compaction, freeze-thaw cycles, and heavy loads on slabs.
