Premium Solutions
Customized for Every Home
We fix driveways, patios, walkways, pool decks, and garage floors using state-of-the-art concrete repair and concrete leveling solutions. Our exclusive PolyLevel®, NexusPro®, and SealantPro® systems restore safety, appearance, and long-term protection for your home.
LIFT & RESTORE SUNKEN CONCRETE
Uneven concrete is more than a cosmetic issue. Cracks and sunken areas create trip hazards and foundation stresses. Our PolyLevel® system gently lifts and levels concrete using a lightweight expanding foam that won't wash out, deteriorate, or add pressure to the soils below.
SEAL CRACKS & JOINTS
Cracks allow water to seep beneath slabs, causing washout, soil settlement, and more cracking. NexusPro® is a UV-resistant, temperature-flexible joint and crack sealant that protects against moisture year-round.
PROTECT CONCRETE SURFACES
SealantPro® extends the life of your concrete by bonding with the surface to guard against stains, moisture, and chemical damage. Just one application lasts for years.
We bring 50 years of experience, exclusive concrete repair products, industry-leading warranties, and award-winning service to every home we visit, in Denver and surrounding areas.

Thrasher's concrete repair specialists inspect your concrete and recommend the right combination of leveling, crack and joint sealing, and surface sealing to restore long-term safety and stability to driveways, patios, walkways, and garage floors.
The benefits of concrete repair service by Thrasher include:
Concrete repair costs less than replacement and PolyLevel® will not degrade, eliminating the need for reapplication.
Foam expands in all directions to stabilize the soil, fill voids, and improve the weight-bearing values of your concrete.
Fix dangerous trip hazards and potential structural problems by leveling concrete and keeping it firmly in place.
Repairing the concrete instead of demolition keeps it out of landfills. Plus, PolyLevel® will not leach chemicals into the soil once cured.
Short cure time means you can use your concrete as normal much faster than other methods of repair.
Small penny-sized burr holes are drilled where the solution is injected. The chemicals are mixed inside the nozzle upon application.
Damaged concrete hurts curb appeal, lowers home value, and poses safety risks. Repairing it now prevents further settlement, moisture intrusion, and costly replacements.
