Coordinate external membranes, waterstops, drainage boards, subsoil drainage, sump systems and maintainable details.

Assess groundwater risk
Design for seasonal high water levels and hydrostatic pressure, not average dry-season conditions.
Select an external system
Positive-side waterproofing is normally more reliable than attempting to stop water from inside later.

Coordinate joints
Construction joints, pile caps, raft edges and service entries need project-specific details.
Provide drainage and access
Drainage reduces pressure, but outlets, sumps and pumps must remain accessible for maintenance.
