## Page content

A retaining wall without proper drainage and waterproofing is a dam waiting to fail. In coastal Croatia, heavy autumn rains and sloping terrain mean that retaining walls must manage significant hydrostatic pressure. The most common mistake is backfilling with excavated soil instead of washed gravel, combined with missing or crushed drainage pipes. Correct execution requires a clean concrete surface, continuous waterproofing membrane, dimpled protection board, perforated drainage pipe at the footing, and a full column of washed gravel wrapped in geotextile. Verifying this assembly before the contractor backfills the wall is one of the most critical checks during house construction.
