Cause

Spalling concrete due to reinforcing corroding

Repair

  • saw cut around the damaged area (if not extensive); remove damaged concrete until uncarbonated or chloride-free concrete is reached; replace severely corroded reinforcing steel; treat rust by sand blasting; paint with zinc-rich paint; brush with cement slurry (paste); replace concrete

Cause

Soil subsidence under/against pool

Repair

  • saw cut around the damaged area (if not extensive); remove damaged concrete until uncarbonated or chloride-free concrete is reached; replace severely corroded reinforcing steel; treat rust by sand blasting; paint with zinc-rich paint; brush with cement slurry (paste); replace concrete

Cause

Poor design or installation

Repair

  • saw cut around the damaged area (if not extensive); remove damaged concrete until uncarbonated or chloride-free concrete is reached; replace severely corroded reinforcing steel; treat rust by sand blasting; paint with zinc-rich paint; brush with cement slurry (paste); replace concrete
