Interior wall remains wet where soil bears against the structure.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Interior wall remains wet where soil bears against the structure.
Review groundwater, drainage outlet, backfill, membrane damage and construction joints.
Hydrostatic load increases when drainage is blocked or protection is damaged during backfill.
Where access permits, repair positive-side barrier and drainage as one assembly.
Check protection board and drainage before backfill; use suitable backfill and avoid puncturing the barrier.
Record drain flow and inspect wall after a wet cycle.
An interior coating alone may hide pressure and salts without correcting drainage.
