How A-1 Lifts Settled Concrete
ControlLevel™ is A‑1's standard for concrete lifting, refined since 1982. With specialized equipment, a limestone-based stone slurry, and trained technicians ControlLevel gives A‑1 Denver South greater control over the flow of material and the pace of the lift, for maximum precision and minimum disruption.

Raise settled concrete to a safer, more even position with A‑1's exclusive ControlLevel™ System.

Seal open joints and cracks to help limit water intrusion while allowing seasonal movement.

Clean built-up dirt, algae, and staining from the concrete you already have.

Seal the surface so water, salt, and everyday wear soak in more slowly. It's the maintenance step that buys a slab years.
Save up to 70% vs. replacement
Across A‑1 locations, most residential ControlLevel™ jobs cost $1,100 to $1,500.
Your price depends on the size of the area, the void beneath it, and how far the slab has dropped. Get your exact number with a free, on-site estimate from A‑1 Denver South.
Eco-friendly, limestone-based stone slurry
(a mineral mix, batched on site)
Decades
Settling that has not stopped will move any repair.
High compressive strength
The slurry fills the void it flows into. Support ends up even across the slab.
$1,100–$1,500
Across A‑1 locations (up to 70% less than replacement)
Low
The material is adjusted in real time for maximum precision
Walk on it right away
Drive within 24 hours
Expanding polyurethane foam
(often a two-part synthetic resin)
Decades
The same rule applies to any leveling method.
Depends on the fill
Foam expands unpredictably and may not fill the whole void, which leaves unsupported spots.

Sunken concrete in areas like Cherry Creek or Littleton usually starts below the surface: the soil beneath a slab shifts, erodes, or can no longer support it evenly. Water can enter through open joints, cracks, and slab edges. As it moves through the ground, soil may soften or wash away, leaving empty spaces beneath the concrete. Without consistent support, part of the slab begins sinking. Seasonal freezing and thawing can add movement as moisture in the soil freezes, expands, and later thaws. Drainage problems, poorly compacted fill, tree roots, and burrowing animals may also contribute.
A large portion of the Denver South area is bentonite clay, a soil that swells when it gets wet and shrinks back as it dries. Add the freeze-thaw cycles the Front Range sees each winter, and slab edges are especially prone to settling.
While the causes of sunken and damaged concrete are pretty similar across the greater Denver South area, what you're seeing may be completely different than someone up the road.

They're different tools. Mudjacking-style leveling pumps a natural slurry beneath the slab; foam injects an expanding synthetic. A‑1's ControlLevel™ system gives the technician live control of the lift.
Mudjacking is the traditional name for lifting concrete by pumping material beneath it. ControlLevel™ is A‑1's modern version: a limestone slurry, specialized equipment, and a slow, controlled lift.
Raising settled concrete back to a safer, more even position without tearing it out. Also called concrete lifting, mudjacking, raising, or slabjacking.
Small holes are drilled in the slab, material is pumped beneath to fill the voids, and the slab is guided back to position. With ControlLevel™, the technician monitors and adjusts the entire lift.
Most repairs can last for the life of your concrete. Longevity depends on the conditions beneath the slab, drainage, and upkeep like caulking and sealing.
If the slab is still solid, leveling usually wins: a fraction of the cost, done in a day. If it's crumbling or structural, replacement is the honest answer, and we'll tell you.
No. A‑1 Denver South uses its exclusive ControlLevel system to lift concrete, with precision, into a safe, even position. The ControlLevel system pumps a stone slurry grout material (limestone and water) beneath the surface for maximum void fill and long-lasting strength.
Usually the adjoining property owner, but rules vary by city. Check your city's sidewalk program; if the repair is yours, A‑1 can level it for far less than replacement.
Often, yes. Frozen ground can limit some lifts, but many projects run year-round. Your local crew will tell you what your slab needs.
