DELTA NP Drainage sheet
DÖRKEN Delta NP Drainage Sheet is a high compressive drainage sheet that provides high drainage capacity through specially configured dimples. The product is perfect for most vertical applications in building, underground and civil engineering construction. The product is available in 2.0m x 20.0m rolls and has an integrated geotextile fabric to filter out suspended soil particles, ensuring constant drainage through the vertical void created by the dimples. DÖRKEN Delta NP has a dimpled membrane on one side offering added protection to the waterproofed surface. The dimples create a void between the wall and the backfilled area offering dependable vertical and horizontal drainage in civil engineering, buildings, retaining walls of all kinds, open tunnels and underground carparks.
