What is involved in concrete floor repair?

Concrete floor repair typically involves four steps: assessment (identifying the type and extent of damage using visual inspection, hammer testing, and sometimes core sampling), preparation (removing damaged concrete back to sound material using diamond grinding, scabbling, or hydro-demolition), priming (applying a bonding agent to ensure the repair material adheres), and reinstatement (placing the repair mortar, micro-concrete, or resin system). Common floor defects include cracking, joint arris damage, surface spalling, potholes, and delamination. Repair materials are selected based on the load requirements — epoxy mortars for heavy forklift areas, polymer-modified cementitious mortars for general use, and rapid-set systems when downtime must be minimised.
