No matter how well your concrete is installed and maintained, it's entirely possible you'll need repairs at some time. It's also possible that you purchased a fixer-upper and it's time to get to the fixing. Austin Concrete Pros is rested and ready to help you.
The first thing we'll do is clean up the area around patch. Remove any large debris and scrub the area with a wire or other stiff bristled brush. Then it is simply a matter of applying a concrete patching material similar to Spackle on interior walls. Take a trowel and force the patching material into the crack. Once that it is complete, it will take an hour or so for a surface skin to form and will become hard in about 6 hours. We still recommend you wait several days before you let the patch get wet or heavy traffic.
It can be tempting to blame the original contractor when concrete warps. Sometimes a third party forces the contractor to lay the concrete before the ground underneath the has a chance to settle. If a gutter is improperly installed it can wash away the underlying soil. Of course, a concrete contractor could have done a bad job (known as "slab curl"), but it is generally caused by shifts in the ground underneath the slab.
No matter the cause, we'll drill holes into the concrete. Big ones if we're using mud to lift it and smaller ones if we're using foam to lift it. We'll pump the lifting material into the holes. Once that material has lifted and leveled, we'll patch the drilled holes just like any other patch job. The best part is that this is a very quick job. It generally only takes a few hours to do the drilling and actual lift. You can walk on the slab in a few hours and drive on it in a day.
