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.

Versicell Drainage Cell

VesiCell offers architects and developers greater design flexibility and has a wide range of applications in the landscape, building and construction industries.

VersiCell® is a lightweight interlocking plastic structural module used for subsurface drainage or to form tanks for underground water percolation systems.

When installed with a waterproof membrane, VersiCell® eliminates the need for an additional protection layer.

VersiCell® modules are easily interlocked in the same plane (a) or at right angles (b) to one another. They may be butted together without interlocking.

Design Flexibility

Greater design flexibility as the modules may be interlocked in one plane or at right angles to one another to form continuous large panels, conduits and tanks.

Easy Installation Large easy-to-join modules or pre-assembled panels allow rapid installation and minimise on-site disruption.

Lightweight and High Strength Honeycomb design results in a lightweight high compressive strength structure.

Durable

The modules are resistant to biological attack and to a wide range of chemicals.

Efficient

High surface void area and internal void volume results in efficient drainage. Narrow profile enables a greater soil depth to be utilised in planter beds allowing the use of a wider variety of landscape plants.

Environmentally Friendly

VersiCell® is manufactured from high strength recycled plastics.
