Concrete Floor Repair

Crack, spall, joint and salt-damage repair for garage, basement and commercial concrete floors in Cicero and nearby towns.

Cicero Epoxy Flooring handles concrete floor repair in Cicero, IL, serving surrounding cities including Forest Park, Lyons, River Forest, Brookfield and Summit. Repair is where many coating jobs are won or lost, and in more than 20 years of grinding and coating floors we have learned to map cracks, spalls and old coatings before anything else is planned.

Repairs are done either as preparation for an epoxy or polished floor or as a standalone service. Either way, we tell you plainly when a slab needs replacing or leveling rather than patching, because no repair or coating holds together concrete that is still moving apart.

Most of Cicero’s homes were built in 1939 or earlier, and their garage and basement floors carry decades of settling, old patches and salt damage. Those floors can usually be brought back, but only with repairs chosen for what actually went wrong.

Cracks in Concrete Floors

Static and Moving Cracks

Not every crack is the same. A static crack formed as the concrete shrank and has not moved since, while an active crack still opens and closes with settling, frost or heavy loads.

We look at crack width, offset between the two sides and signs of recent movement before choosing a repair. Static cracks get a rigid fill that can be ground flush, while active cracks get flexible materials or are turned into planned joints.

Filling and Grinding Cracks Flush

Cracks are cut open with a diamond blade or crack chaser to remove loose edges and give the filler something to hold. They are vacuumed clean and filled with epoxy, polyurea or a cementitious repair material.

Once cured, the fill is ground flush with the surrounding floor. That gives a flat surface that a coating can go over or that can be polished along with the rest of the slab.

When Cracks Signal Bigger Problems

Wide cracks with one side higher than the other, cracks that keep growing or networks of cracks over soft, hollow-sounding concrete point to problems below the slab. Patching the surface will not fix them.

We tell you when a floor needs leveling, sub-base repair or partial replacement before it is worth repairing or coating. That honesty saves money compared with coating a floor that will crack again.

Spalls, Pitting and Salt Damage

Spalled and Broken Areas

Spalls are chunks broken out of the surface, often along joints, edges and near drains. They catch tires and wheels and keep growing as edges crumble.

We cut spalled areas back to sound concrete with clean, square edges and fill them with an epoxy mortar or fast-setting repair compound. The repair is then ground level with the rest of the floor.

Salt Scaling on Garage Floors

Winter brine, rock salt and calcium chloride come in on tires and soak into bare garage concrete. As that salty water freezes and thaws, the top layer flakes away and leaves a rough, pitted surface.

Scaled areas are ground to sound concrete and resurfaced or filled. A coating afterward keeps salt from reaching the concrete again, which is the only way to stop the damage from returning.

Pitting and Surface Wear

Old slabs often have pits, popouts and worn paths where the surface paste has eroded. These hold dirt, trap water and show through thin coatings.

We fill pits with a fine patching compound or a body coat of 100% solids epoxy that builds the surface back to an even plane. On polished floors, small pits are filled with a grout coat during the grinding steps.

Joints, Edges and Drains

Control Joint Repair

Control joints are cut into slabs so they crack in a straight line instead of randomly. Over time, joint edges chip and open, especially under carts and forklift wheels.

We rebuild broken joint edges with epoxy mortar and refill joints with a semi-rigid filler that supports wheel traffic while allowing slight movement. On a coated floor, joints can be honored as visible lines or filled and coated over.

Edges Near Garage Doors

The edge of a garage slab at the door takes salt, water, tire impact and frost more than any other spot. It is often the first place a floor breaks down. We rebuild crumbling door edges with repair mortar shaped to the original profile, so the door still seals and water still runs outward.

Floor Drains and Sloped Areas

Basement and commercial floor drains often have broken concrete around them where water, cleaning and settling have worked on the edges. We rebuild drain surrounds so they slope properly and give a sound edge for the coating to stop against.

Repairs around drains do not change how a drain behaves in a sewer backup, though. In Cicero’s combined-sewer system, a backflow valve or overhead sewer is what keeps water from coming up through the floor.

Repair Materials Matched to the Floor

Epoxy and Polyurea Fillers

Epoxy mortars are strong and bond well to dry concrete, making them good for spalls and static cracks indoors. Polyurea fillers cure quickly and keep some flexibility, which suits joints and cracks that move slightly. Both can be ground flush and coated over, and both set fast enough to keep a project on schedule.

Cementitious and Urethane Cement Repairs

Cement-based patching materials suit areas that will stay bare or be polished, since they look and wear more like the original slab. Urethane cement mortars are used in commercial kitchens and food plants where repairs face hot water and harsh cleaners. We choose the material based on traffic, chemicals and the finish going on top, not on what happens to be on the truck.

Frequently Asked Questions

Can every cracked concrete floor be repaired?

Most cracks and surface damage can be repaired, but a slab that has settled badly, heaved or broken into loose sections may need leveling or replacement instead. We tell you which category your floor falls into before quoting repairs or a coating.

Will a repaired crack come back?

A crack in a slab that has stopped moving usually stays closed once it is properly filled. A crack that is still moving, from settling, frost or loads, can reopen, so we check whether cracks are active and choose flexible or rigid fillers to match.

What causes the surface of my garage floor to flake off?

That is usually scaling from deicing salt and freeze-thaw cycles. Salty water from car tires soaks into the concrete, freezes and expands, and breaks off the top layer. Repairing the surface and sealing it with a coating stops the cycle.

Can you fix a basement crack that leaks water?

A crack that actively lets water in is a water problem first, often driven by hydrostatic pressure under the slab. Surface filler will not hold back that pressure, so we recommend addressing drainage or waterproofing before repairing the floor surface.

Do repairs show through a new epoxy floor?

Under a flake system, repairs are usually hidden by the broadcast. Under smooth metallic or solid color finishes, repaired cracks can show as faint lines, and we discuss that before choosing a finish.

Do you repair concrete floors without coating them?

Yes. Crack, joint and spall repairs can be done on their own for floors that will stay bare, be polished or receive another finish. We match the repair material to how the floor will be used.
