Possibly! Repairs typically save the homeowner money compared to removal and replacement. Mendenhall Concrete will be able to evaluate your damaged concrete and make this determination based on site conditions.

Some common applications include broken stair or curb corners, slab cracks and spalled areas of concrete flatwork, cracked, spalled or leaning retaining walls, and exposed or washed-out deck footings.

What Causes My Concrete to Break?

Aside from the obvious damage that can occur from equipment, vandalism, or seismic activity, another common reason that concrete breaks or spalls are rebars being placed too close to the surface of the concrete. The concrete allows water and moisture to cause rust, which expands and causes breakage and spalling.

Another very common reason for concrete damage is shifting soils or expansive/compressive soils. Lastly, if the concrete is improperly mixed and/or cured, it will not reach its desired strength and can deteriorate over time.

How Is Concrete Repaired?

There are a variety of methods to properly repair concrete. In addition to crack repairs, broken or spalled concrete can be properly repaired using a variety of methods. Before concrete can be repaired, the damaged area must be thoroughly cleaned where any loose and unstable material and dust/dirt particulates are removed. When appropriate, reinforcing steel (rebar) is epoxied into the existing concrete to reinforce the repair.

Dry Pack Method

After cleanup (for smaller repairs), a method called “dry packing” can be used. A cement or grout mixture is mixed with water and/or polymers for elasticity and adhesion in a very thick consistency similar to clay or putty. The repair area is primed with concrete adhesive (as required by the manufacturer), and the structural repair mortar is hand-applied and formed to replace the broken sections.

Form-and-Pour Method

For larger repairs, it may be necessary to create a form or mold for the concrete to be placed into. Formwork is typically fastened onto the existing surface being repaired, braced and sealed, and removed after the concrete has been placed and hardened. The formwork is then removed, and any imperfections are patched with repair mortar or grout.
