What chemicals are used for concrete repair and rehabilitation?

Concrete repair uses bonding agents (SBR or acrylic latex), polymer-modified repair mortars, epoxy injection systems for cracks, micro-concrete for structural repairs, and anti-corrosion coatings for exposed reinforcement. Complete systems are available from Sika, Fosroc, and MC-Bauchemie.

How do I fix cracks in concrete walls and slabs?

For structural cracks over 0.3mm, use low-viscosity 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 selecting the repair method.

What is the difference between grouting and repair mortar?

Grouting is flowable and used to fill voids, anchor bolts, or underpin foundations. Repair mortar is trowel-applied and used to reinstate lost or damaged concrete sections. Both are essential in structural rehabilitation projects.
