A-1 works throughout Thornton, including Avery Lake Estates, Bramming Farm and Brantner Village, and along the routes that connect them: Colorado Boulevard, East 104th Avenue and East 112th Avenue.
Based in Denver North, your A-1 team is the exclusive provider of the ControlLevel™ system — lifting settled slabs around Northglenn, Henderson and Federal Heights and the surrounding areas back to a safer, more even position without the cost and disruption of tear-out and replacement.
Some of the best parts of life in Thornton are outdoors — places like Badding Reservoir, Thorncreek Golf Course and Adams 12 Five Star Stadium. Your own driveway and patio should be as safe as the places around them, so A-1 levels uneven concrete before a small trip hazard becomes a bigger problem.

Detached homes carry the most concrete per property — driveway, garage floor, walkways and patio.
According to the U.S. Census Bureau’s American Community Survey, only about 23% of homes in and around Thornton, Amber Creek and Ash Grove Farm (Planned) were built before 1980. Settlement in newer construction is usually not about age — it traces to backfill around the house and utility trenches compacting after the pour, which can leave a slab unsupported inside its first decade or two.
Roughly three quarters of the ground under Thornton is clay that swells when it gets wet and shrinks back as it dries, according to USDA soil survey mapping — and concrete sitting on moving ground eventually loses the support it was poured on.

ControlLevel™ is A-1’s standard for concrete lifting, refined since 1982. It brings together specialized equipment, a limestone-based stone slurry, trained technicians, and a controlled process that responds to the conditions beneath each slab.
Together, those elements give A-1 greater control over the flow of material and the pace of the lift, helping us raise settled concrete carefully, minimize disruption, and avoid unnecessary tear-out.
Holes are drilled, about the size of a quarter.
Mixture is pumped beneath the concrete slab.
Hole is patched, and you can use it right away.
A-1 lifts concrete on many properties across Thornton, including the Ash Meadows at Sage Creek or Autumn Creek areas. A slab generally needs to be largely intact to be a good candidate for lifting — cracked concrete may still qualify when the sections can be stabilized and raised together.
From lifting settled slabs, to protecting the concrete you already have, A-1 provides services for homes and commercial properties throughout the Denver North area.
Yes. Thornton is served by the A-1 team based in Denver North, and the estimate happens at your property rather than from a map — conditions change street to street. Call (303) 558-0000 to confirm service for your address and book a free on-site estimate.
A-1 Concrete Leveling serves Thornton homeowners and commercial properties with leveling, caulking, cleaning and sealing. Leveling lifts settled slabs back into position, caulking seals the joints and cracks that let water reach the soil underneath, and sealing protects the surface from the freeze-thaw and moisture cycles that wear it down — together, they keep concrete usable far longer than replacing it piece by piece.
Most homes here are newer, and settlement usually traces to backfill and utility trenches compacting after the pour rather than the age of the slab.
Often, yes. A slab that has settled but stayed largely intact is usually a good candidate. The on-site estimate is where A-1 confirms whether lifting or replacement makes more sense.
