Geotex Dimpled Wall Drains are made from a cuspated core, bonded to a high quality non-woven geotextile.

The core’s high compressive strength resists high loads from in-fill and formwork. Its stud-shaped dimples provide an air chamber between the sheet and wall to rapidly channel water from grade to the footer drainage system. It is resistant to saline solutions, alkalis and acids.

The dimple height can vary from 10mm to 30mm depending on the requirements. The material is supplied as rolls, either 1200m x 20m or 2400mm x 20m. For larger applications the dimples along the edges of the sheets can be pressed together on site, to form a wider sheet. The high quality abrasion resistant, non-woven geotextile covering the dimples prevents soil particles blocking the drainage sheet, creates an air gap for reliable ventilation and provides hydrostatic relief by allowing high volumes of filtered water to pass into the drainage core. Each roll comes with a 150mm geo-fabric overlap along one edge.

Applications
The lightweight and flexible drainage mats provide effective drainage on foundation walls and other underground structures. Available in a range of sizes, they are a cost effective option for:
• Shot-creting applications;
• Leak detection at the base of lined channels;
• Vertical drainage on very steep slopes or vertical walls in place of traditional aggregate drains;
• Above ground gardens.
