Elevator pits and vaults often become damp or hold water. Elevator pits and vaults are often the lowest part of the building. Additionally, when buildings with elevators are built near water there is water pressure pressing on the walls and floor. Just like a basement, an elevator shaft is below ground and is subject to humidity. Wet elevator shafts need to be addressed.
Water will find the path of least resistance, and whether through the freeze thaw process or as a result of water pressure on the walls and floor, water will find the cracks and holes in the shaft. Over time the water breaks down the mortar and concrete and rusts the structural rebar holding the walls together, resulting in structural damage to the elevator shaft.
If you have noticed wet floors, dark patches, or crusty white buildup, this is an indication of water trying to get into the building. Contact A1 Foundation Crack Repair.
