Waterproofing
A system intended to resist water penetration under the exposure conditions for which it is designed.
Why it matters
Below-grade walls, terraces, and roofs face different conditions. Confirm drainage, joints, penetrations, and protection of the system rather than treating a coating as a complete solution.
In practice
A project example
A terrace membrane repair must address the door threshold and drain connections where leakage is occurring.
