How to repair damaged concrete floors and slabs

REPAIRING POTHOLES IN CONCRETE FLOORS AND SLABS

For repairs to concrete floors and slabs that have suffered from general wear and tear, erosion and impact damage.

Repairing a pot hole in a concrete floor slab

METHOD

  • Saw cut around the perimeter of the repair area.
  • Break out loose and damaged concrete leaving a sound flat base for repair.
  • Prime the sides and base of the repair area.
  • Whilst the primer is still wet/tacky apply and compact the repair mortar. Allow sufficient time for the repair to gain strength before trafficking.
  • For repair depths of 3-50mm use epoxy resin mortars particularly where chemical resistance is required.
  • For repair depths of 10-100 use cement based mortars where applicable. Spray with water and cover with plastic sheet to reduce shrinkage or spray with a curing compound.
