Safe for humans and the planet.
Our polyurethane foam is eco-friendly. It doesn't leech harmful chemicals into the soil. It's safe to use around homes, gardens, and water sources.

Stop the void from getting worse!
Until the void is filled, water will continue to erode the soil and increase the void, weakening the concrete until it breaks or sinks.
Displace the “erosion fuel” below your slab
Water acts as erosion fuel. When the void is filled with polyurethane foam the water has no place to fill and erosion stops.
Our poly foam fills the void, bonds with the concrete and soil making it impossible for water to continue eroding.
Fast, affordable, and environmentally righteous? Yes!
It's rare that a service is the faster, more affordable, and more eco-friendly than the alternative. But with our poly foam void fill, it's the uncontested winner over traditional mudjacking.
Eliminate future expenses
Stop future concrete cracks before they happen and avoid worsening safety hazards.
Increase load-Bearing capacity
Restore your concrete slab's load-bearing capacity back to original so you can safely use it like before.
Eco-Friendly
Zero harmful chemicals leech into the soil and the poly foam is made from recycled material.
Zero Intrusion
Our poly foam void fill process doesn't require tearing up your yard or landscaping with heavy equipment.
Zero trace repair
When we leave the jobsite you won't be able to tell we were there, execpt that your concrete slab will be safe, strong, and level. It's like magic.
Same day use
The minute we're done, you can use you're concrete. Usually customers will leave for work in the morning with sinking concrete and when they return that evening it's leveled and they can use it.
Permanent
Using polyurethane foam for filling void below concrete is a permanent fix unlike mudjacking that is only a temporary fix and will need to be re-done regularly.
Money & Time Saver
Void fill is usually half the cost of replacing the concrete and can be done in 1 day.

Testimonials
We are pleased with the Troyer Concrete Solution approach that Lowell Troyer performed on our home’s back patio concrete slab.
We had major cracks across the length of the slab as a result of the ground drying and dropping over time. This caused the front portion of slab to tilt lower and air pockets to form between the bottom of the slab and the current ground level.
He was able to raise the affected sections of slab to level the overall slab front. He also added polyfoam across other sections of the slab to fill in air pockets and thereby strengthen the overall slab.
We feel this work will improve the longevity of our home’s back patio concrete slab.
Thank you for finding a solution to our sidewalk nightmare! We really appreciate you!
Troyer Concrete did an excellent job for us, and I highly recommend their services. Great people with great quality workmanship!
