How to Repair Concrete
Other than earth movement, moisture is the main cause of cracks in concrete. Here's how to deal with moisture damage. Does this Spark an idea?
Instructions
-
-
1
Clean out cracks of any size as best you can, using a wire brush or even a strong spray of water.
-
2
Fill small cracks (less than 1/8 inch) with caulk specially made for concrete. (Be sure cracks are dry before caulking.)

3
Fill larger cracks or small holes (less than a few inches) using patching products designed for concrete. These usually are in the form of a powder that is mixed with water. They typically expand as they dry and become very hard.
-
4
Apply sealant or paint to the concrete.

The best concrete patch i ever used, inside and out was Belzona. Amazing stuff, expensive but you do it one time. -
