Elevator pit and stairwell waterproofing that seals leaks, adds sumps and drains and protects equipment in the lowest parts of a building.
Elevator pits and below-grade stairwells sit lower than almost everything else in a building, so water finds them first. A little seepage can corrode equipment, trip safety systems and make the space unpleasant to maintain. These areas are small and hard to work in, which is why many owners put off fixing them. Around Nashville, buildings of all ages have this problem, and fixing it early helps protect the rest of the building and the people who use it.
We inspect the pit or stairwell with the building engineer or elevator contractor, noting leaks, cracks, joints, floor drains and the condition of equipment. We coordinate lockouts and access. We seal cracks and joints with injection, hydraulic cement or crystalline products, add or repair sumps and drains and install proper pumps and discharge lines in coordination with the elevator and plumbing trades. For stairwells, we address wall seepage, window wells and floor drainage. We follow safety procedures for confined spaces, and we document the work for the owner and the maintenance team.
