Planning
Design substrate preparation, corners, joints, penetrations, protection, drainage and discharge as details. Finished ground leads water away and maintenance points remain accessible.

Install waterproofing, drainage and protection layers
Waterproofing works only as a continuous, protected and tested envelope.
Material choice and build-up depend on water exposure, substrate and details. Drainage membranes do not replace required waterproofing, and unprotected waterproofing can be damaged during backfill.

Decision compass
Decide safely
Four questions lead from observation to a clear, safer action.
What needs to be clarified now?
What must I notice first?
- Record household needs, dependencies, current official information and available safe locations.
- Agree responsibilities, communication rules and a fallback before time pressure develops.
Remember: Observe → assess → choose a safer option → act.
Waterproofing works only as a continuous, protected and tested envelope.
Learning goals
- Coordinate a continuous envelope from base to joints and roof
- List nearby hazards and every connected system
- Record the test result, responsible person and maintenance date
Inspection
Inspect substrate, laps, junctions and damage in stages. Complete documented acceptance before backfilling. Repair and recheck suspect areas.
Operation and maintenance
Inspect outlets, access points and interior after heavy rain. Record moisture trends and odour so gradual change is detected early.
Practical check
- Coordinate a continuous envelope from base to joints and roof
- Record conditions with photographs and a plan
- Assign responsibility
- Test function under realistic conditions
- Document results and maintenance date
Important
- Do not build without required specialist design
- Never trade escape routes or safe air for storage
- Do not present unverified assumptions as protective performance
Decision training
What must be checked before work begins on “Install waterproofing, drainage and protection layers”?
- ABuild immediately by improvisation
- BDocument conditions, obtain the required assessment and then test
- CPostpone the issue until an emergency
Show answer
Correct: B. Photographs, plans, specialist checks and a functional test show whether the proposed solution works safely at the actual site.
