Below-grade wall waterproofing for commercial and large residential buildings, with membranes, protection board, drains and joint details that resist constant water.
Walls below the soil line live in a hard place. They are surrounded by damp soil, pressed by groundwater and sometimes stretched by settling or temperature. A weak spot at a joint, a penetration or a transition can let in water for years before anyone notices. Large buildings and big homes around Nashville often have deep basements or garages with tall walls, and the waterproofing system needs more than a coat of paint to do its job.
We review drawings, soil reports and site conditions and propose a system that suits the wall and the water. That may include fluid-applied or sheet membranes, protection board, drainage composite, footing drains, penetration seals and joint tapes or waterstops. We check substrate prep and details at corners, transitions, pipes and beams. We coordinate with the general contractor, the engineer and other trades, and inspect and photograph before backfill. For existing buildings, we assess leaks and propose repair, injection or interior drainage as a practical solution. We document products and areas for the owner.
Below-grade walls face damp soil, groundwater and movement.
Joints, corners and penetrations are where leaks begin.
Board and drainage layers shield it from backfill and carry water down.
Repair, injection and interior drainage can manage leaks after the fact.
Membrane, board and drain are chosen for the conditions.
Corners, penetrations and joints get the most attention.
Walls are cleaned and repaired before coating or sheet goes on.
We work with the GC, engineer and other trades.
Photos and checks happen before the soil goes back.
Repairs and interior drainage can solve leaks after the fact.
