Concrete Crack Repair Key Terms

Learn about common terms relating to concrete crack repair

Concrete crack repair is necessary for safe, efficient and durable functioning of a concrete structure. Repairing cracks in the concrete helps to cover imperfections through use of various crack repair chemicals and materials.

If you want to be a consultant or contractor of concrete crack repair, you will need to understand various technical terms relating to the process. In this guide, we will cover some key terms related to concrete crack repair such as the compressive strength, tensile strength, epoxy, surface preparation and curing.

Compressive strength

Compressive strength is the ability of a material to withstand stress and load that tends to crush it. As a consultant in the field of concrete crack repair, you must be aware of the compressive strength of different materials.

Tensile strength

Tensile strength (also known as ultimate strength) is the ability of a material to withstand longitudinal stress before breaking. Different standardization organizations publish information about tensile strengths of standard materials and standard testing methods.

Surface preparation

Surface preparation is an important step in the process of repairing a concrete crack. Proper surface preparation ensures adhesion of the epoxy to the cracks that are to be repaired.


Curing is the process of setting and hardening of cement or epoxy material. Proper curing is necessary for durable concrete surface and repair work.

Caulking compounds

Caulking compounds are useful for repairing the cracks and joints in concrete surfaces. These compounds are available with different adhesive properties (as per application requirements) and are either water-based or solvent-based. Caulking guns are required for the application of caulking compounds.


Epoxy is a polymer material that has a high strength. An epoxy consists of a resin and a hardener, which react and harden upon mixing.
