Drainage mats PETEXDREN 400 and PETEXDREN 900 consist solely of the drainage core, while PETEXDREN 900+300 is laminated by non-woven filtration geotextile from one side.
The product is offered in the width of 1.5m, and in lengths of 50m (PETEXDREN 400), 35m (PETEXDREN 900) and 30m (PETEXDREN 900+300). The colour of the drainage core is black, the composite filtration geotextile is white.
Drainage mats PETEXDREN are characterised by high water permeability both in and normal to the plane. When compared to the commonly used granular drainage materials, the major benefit of our drainage mats is their low weight which makes all handling and installation highly convenient.
In engineering applications, the product performs primarily the drainage function, as well as the functions of separation and filtration.
Drainage mats PETEXDREN are manufactured and tested in accordance with relevant harmonised EU standards for geotextiles and geotextile-related products. The products bear CE marking.
