Serving Decatur, IL and surrounding areas. (217) 917-9824
Hollow spots, persistent cracks, or a moisture problem you cannot shake? We replace basement and garage floors in Decatur from demo through final pour - with proper base prep for clay soil and no line items that appear after the fact.
Concrete floor installation in Decatur, IL means breaking out the old slab, compacting the clay soil underneath, adding a gravel drainage layer, and pouring a new four-inch reinforced slab - most residential jobs take one to two days of active work, and the floor is ready for normal use about 28 days after the pour.
Decatur has a large share of homes built before 1960, many with basement floors that are thin, unreinforced, and showing the effects of decades of Macon County clay soil movement. Getting the base preparation right before the new pour is the single most important factor in whether your replacement floor lasts 5 years or 50. Rushing it - or skipping the gravel layer - is what causes cracks to come back.
If your project is a garage floor and you want to step up the finish, we also offer garage floor concrete with decorative finish options that go beyond a standard gray slab - worth asking about when you call for an estimate.
If you have patched the same cracks and they keep coming back, the problem is under the surface. In Decatur, clay soil shifts every season, and no amount of filler fixes a moving base. When cracks are wider than a pencil or you feel a lip between the two sides, patching is no longer enough.
Walk slowly across the floor and tap it with your heel - a hollow sound means a void is forming underneath. The soil has shifted or washed away, leaving the slab unsupported. An uneven floor that rocks furniture or makes doors stick tells the same story. Both signal the slab needs replacement, not another patch.
A chalky white residue on your concrete floor means water is moving up from the ground below - a common issue in Decatur basements given the clay soils and seasonal moisture. Damp spots that appear after rain and never fully dry will not improve on their own and will damage anything stored on the floor.
Many older Decatur homes were built with basement floors only two to three inches thick - thinner than current standards and often poured without reinforcement inside. If your home is more than 60 years old and the floor has never been replaced, it is much more vulnerable to the soil movement common in this area.
We handle full concrete floor replacement for basements, garages, utility rooms, and crawl space conversions - including demolition of the existing slab, soil compaction, gravel base, moisture barrier if needed, and a new four-inch reinforced pour with the finish of your choice. A broom finish is standard for garages and utility areas. For basements being converted to living space, a smooth trowel finish or polished surface gives you a clean starting point for tile, vinyl plank, or painted concrete.
For larger residential or light commercial spaces, we also work alongside concrete pool decks projects where a coordinated outdoor surface finish is needed around the perimeter of an existing pool - reach out and we can discuss whether both can be scheduled as part of the same mobilization.
Best for Decatur homeowners with cracked, thin, or moisture-compromised original slabs in homes built before 1970.
Suits homeowners who want a clean, level, durable surface that handles vehicle weight and seasonal temperature swings.
Good fit for converting an unfinished basement to living space - leveled, sealed, and ready for your finish material of choice.
A large share of Decatur homes were built before 1960, and many of those original basement floors were poured thin and without reinforcement. The clay soil common across Macon County has been shifting under those slabs for 60-plus years, and by the time most homeowners call us, the floor is cracked, hollow in spots, and showing signs of ground moisture. Replacing it is straightforward - but only if the base is prepared correctly for local conditions. Pouring over unstable clay without compaction and a gravel layer is how you end up with the same cracked floor five years from now.
Decatur also has a higher-than-average prevalence of sump pumps because the local water table and clay soil create real basement moisture issues. We serve homeowners across central Illinois - including Danville and Mattoon - where older housing stock and clay soils create the same combination of challenges we handle every week in Decatur.
We ask about the size of the space, what is there now, and what you want the finished floor to look like. We offer a free on-site estimate - worth taking us up on, because the condition of the existing floor and soil underneath can change the price significantly. We respond within 1 business day to schedule.
Before a single tool comes out, we walk the space with you and point out anything affecting the project - drainage issues, existing cracks, low spots, or signs of moisture. In Decatur basements, this step matters more than in newer homes. We also confirm whether a permit is required and handle pulling it from the City of Decatur.
You clear the space; we break up and haul away the old slab, then compact the soil and add a gravel layer. A moisture barrier goes down if conditions call for it. The concrete is poured and finished in a single day - this is the most time-sensitive part, so the crew works quickly and precisely while the concrete is workable.
Light foot traffic is safe after 24 to 48 hours - heavy use and vehicles wait 28 days. We walk through the finished work with you, look for any surface issues, and discuss sealing if it was not included in the contract. A sealed floor lasts significantly longer and is far easier to clean.
We respond within 1 business day and there is no obligation after your estimate. Concrete season in central Illinois is shorter than most homeowners expect - submit the form and we will call to schedule a free site visit and give you a written price that covers everything, including demo and cleanup.

Macon County clay expands when wet and shrinks when dry. Every floor we install includes proper soil compaction and a gravel drainage layer as standard practice - not an add-on. Skipping this step is why floors crack within a few years in this area.
Decatur has a high prevalence of sump pumps because the local water table and clay soil create basement moisture. We assess drainage and moisture conditions before pouring - not after. Covering a drainage problem with new concrete does not fix it.
Every written estimate from us breaks out demo, hauling, base prep, the pour, and cleanup as separate line items. You know what you are paying for before anyone picks up a tool, so comparing bids is straightforward and nothing appears on the final bill that was not discussed upfront.
The American Concrete Institute sets the standards that define what a properly installed concrete floor looks like - including base prep, curing time, and control joint placement. We work to those standards on every pour, in Decatur and across central Illinois.
