Collection: Drainage Cells & Protection Boards
Drainage cells and protection boards are essential components of below-ground and retaining wall waterproofing systems. Their primary role is to protect the applied membrane from mechanical damage during backfilling while providing a controlled drainage path to relieve hydrostatic pressure against the structure.
This collection includes drainage and protection solutions suitable for use behind retaining walls, basement walls, podium slabs, planters, and other sub-surface or earth-contact applications. Correct selection and installation of these products is critical to membrane longevity, system performance, and long-term moisture management.
Products within this range are typically installed as part of a complete waterproofing system and should be used in accordance with project detailing, manufacturer requirements, and relevant Australian Standards.
