Efflorescence on Foundation Walls in Omaha

This home had a white, chalky substance on the walls, called efflorescence. Efflorescence is the deposit of salts left on masonry after the water evaporates. It appears on surfaces like concrete, retaining walls, stone, and stucco. Though it's not harmful, t's a good indication that water is in the basement. To fix, we installed a vapor barrier and interior drainage system.
