Field Guide to Concrete Repair Application Procedures
Structural Crack Repair by Epoxy Injection
Certain things in life are inevitable. Some are said to include death, taxes, and concrete cracks! The latter is subject to volumes of literature on causes and cures. Some of the more typical causes for concrete cracking include:
- Drying shrinkage;
- Thermal contraction or expansion;
- Lack of appropriate control joints;
- Overload conditions that produce flexural, tensile, or shear cracks in concrete;
- Restraint of movement;
One of the potentially effective repair procedures is to inject epoxy under pressure into the cracks. The injection procedure will vary, subject to the application and location of the crack(s), with horizontal, vertical, and overhead cracks requiring somewhat different approaches. The approach used must also consider accessibility to the cracked surface and the size of the crack.
