Foundation leaks
Understand where water is entering, the conditions around the wall, and the protection your space needs.
Plan the hidden layers
Bring underslab moisture protection and waterproofing wraps into the project before access becomes limited.

A clearer starting point
The layers beneath a slab do different jobs. Clarify vapor control, capillary breaks, and any required waterproofing performance with the project team. Then coordinate the selected assembly, its penetrations, protection during construction, and inspection before it disappears.
Read the related field guideAsk which moisture conditions the specified assembly is intended to address.
Coordinate edges, columns, pits, and service penetrations—not only the open field of the slab.
Discuss readiness, protection from damage, and checks before concrete or backfill conceals the work.
Retain the drawings, material information, approved changes, and photographs of completed details.
