Ausdrain supplies Dorken Delta NP drainage sheets, a high compressive drainage sheet that is suitable for most vertical drainage applications.
Providing high drainage capacity through specially designed dimples on the surface of the material, Dorken drainage sheets also feature an integrated geotextile fabric to filter out suspended soil particles.
This ensures constant drainage when used in:
- basement walls
- car parks
- cut and cover tunnels
- retaining walls; and
- civil engineering construction
Dorken Delta NP is supplied in rolls of 2 x 20m and is lightweight to handle. The rolls can be easily cut to the height and length of the wall up to a depth of 8m.
