What chemicals are used for concrete repair and rehabilitation?

Concrete repair involves bonding agents (SBR/acrylic latex), polymer-modified repair mortars, epoxy injection systems for cracks, micro-concrete for structural repairs, and anti-corrosion coatings for exposed reinforcement. Brands like Sika, Fosroc, and MC-Bauchemie offer complete repair systems.

How do I fix cracks in concrete walls and slabs?

For structural cracks (over 0.3mm), use epoxy injection systems. For non-structural or hairline cracks, flexible sealants or crack-filling compounds work well. Surface cracks can be treated with polymer-modified skim coats. Always identify the root cause before repair.

What is a bonding agent and when is it needed?

A bonding agent (like SBR latex or acrylic emulsion) is applied between old and new concrete to ensure adhesion. It is essential when applying repair mortar, plaster, or screed over existing hardened concrete surfaces to prevent delamination.

What is micro concrete used for?

Micro concrete is a pre-blended, polymer-modified cementitious repair mortar used for structural concrete repairs. Products like Sika Emaco S 488 or Emcekrete Type A are used to repair spalled concrete, corroded reinforcement cover, and damaged structural members.

How do you repair damaged concrete?

Concrete repair involves: 1) Remove loose/damaged concrete to sound substrate, 2) Clean and prime exposed rebar with anti-corrosion coating (MC-Corrodur), 3) Apply polymer-modified repair mortar (Sika Emaco), 4) Cure properly. Technotrade Associates supplies complete repair systems.

What is the best concrete repair product?
