Drainage Board Dimpled Sheet

DELTA-TERRAXX is a highly efficient protection and drainage system, DELTA-TERRAXX is an all-round solution for horizontal and vertical applications on compression resistant substrates. With its fused on geotextile and integrated self sealing edge, this dimpled sheet provides perfect surface drainage.

Horizontal Applications

With DELTA-TERRAXX, large flat roofs or ceilings of buildings and underground carparks may be utilised meaningfully and sustainably. Ideal as playgrounds, leisure facilities, or additional parking space, these areas may also be turned partially or entirely in garden roofs.

Vertical Applications

DIN 4095 rules that all foundations fitted with drainage pipes must be equipped with a surface drainage system. DELTA TERRAXX ensures full compliance with the requiremetns of this standard. When applied to pressure resistant substrates and waterproofing coatings that transmit forces such as perimeter inslation boards, rigid or flexible sealing slurries, waterproof concrete, or cold setting self adhesive waterproofing sheets, the DELTA-TERRAXX protection and drainage system offers a maximum of safety for your basement walls.

Ausdrain HexCell Drainage Cell

Ausdrain modular drainage cells provide a permanent non-clogging void between the building structure and the soil profile allowing an undisrupted flow of excess water to designated outlets.

The smooth surface of the modules protects the waterproof membrane and the 30mm void enables efficient discharge of water and ventilation to the slab surface.

The use of Ausdrain Modules and Filter Fabric in conjunction with a waterproof membrane creates a complete waterproofing and drainage system.

Ausdrain 30mm drainage cells provide a permanent, structural and non-clogging void between the building structure and the soil profile that will not collapse or distort. The void enables a direct flow of water to designated outlets resulting in superior drainage efficiency compared to conventional gravel filled systems.
