Due to its close dimple spacing. ISO-DRAIN 8 DIAGONAL offers excellent compressive strength. It is an ideal material for blinding beds under reinforced concrete, providing advantages over expensive lean-concrete beds which require additional excavation. Supplied in 4 m wide sections, it provides savings of up to 50 % in installation accessories and up to 25 % due to reduced sheet overlap area. The system features extremely low-cost installation while ensuring reliable long-term protection.
The dimpled sheets fulfil the requirements of DIN EN 13967 for surface ventilation, physical protection against backfill material and water impermeability.
