Proper installation begins with preparing a clean and suitable surface. The wall should be checked for major irregularities, loose materials, and defects that may interfere with the waterproofing system. Where required, a compatible waterproofing membrane should be installed before placing the drainage board. The board is then positioned according to the manufacturer’s recommended orientation and fixed using suitable fasteners or approved installation accessories. Joints and overlapping sections must be arranged carefully to reduce the possibility of soil entering the drainage space. If the product includes geotextile fabric, its position should follow the specified installation instructions. The lower section should connect with the planned drainage arrangement so collected water can move towards an appropriate outlet. Workers should avoid unnecessary cutting or damaging the dimpled structure during installation. Before backfilling, the installed board should be inspected to identify loose sections, damaged areas, and poorly connected joints. Correct installation is essential because even a technically good product may perform poorly when basic construction details are ignored.
