Preventing Spalling Concrete In Parking Garages

Spalling concrete can be a major issue in parking garages. Unlike concrete buildings that receive a curtain wall protecting the inside concrete floors from the weather, parking garages are open to the elements of the weather. Since the concrete parking decks are opened to the weather is it especially important to place the rebar in the correct locations and have enough concrete covering them.

A protective treatment that can be done to the parking deck after the concrete has been poured is to apply a waterproofing membrane to the concrete. This membrane will prevent water that is sitting on the concrete parking deck to leech into the concrete causing the rebar to corrode causing a spalled area. This membrane can be applied right after the concrete has cured or years after. This investment will protect the parking garage from future spalling problems that could potentially harm a pedestrian.
