Fix concrete spalling, exposed rebar and concrete cancer in Singapore — professional repair for HDB, condominiums, landed properties and commercial buildings.
Concrete spalling occurs when the surface of concrete breaks off in flakes or chunks, often exposing the steel reinforcement bars (rebar) inside. Also known as "concrete cancer", spalling is a serious structural issue that must be repaired promptly.
In Singapore's humid tropical climate, spalling is caused by water infiltrating concrete, corroding the rebar inside, which then expands and causes the concrete to crack and fall away. Left untreated, spalling can compromise the structural integrity of a building.
Best Waterproofing SG provides comprehensive concrete spalling repair for HDB flats, condominiums, shophouses, carparks and commercial buildings — restoring structural integrity and waterproofing against future damage.
