There is a permanent risk associated with all earth-boundary construction elements, such as foundation walls: They may easily become damp. This is why safe damp-proofing is of such outstanding importance in this context: DELTA-DRAIN provides reliable surface drainage for cellar and retaining walls as well as roof gardens by filtering out fine-grained soil particles, ensuring constant water drainage, and permanently protecting foundation walls. 
 
Benefits:  

 

2 layers - one complete system:  

Layer 1: The two-way dimpled sheet. Featuring dimples on both sides, it offers two advantages: On the one hand, the dimples between the foundation wall and the sheet create a system of ventilation ducts which keeps the foundation wall permanently dry. On the other hand, the dimples that point towards the surrounding soil provide drainage across the entire surface.

Layer 2: The compression-resistant permanent geotextile made of PP. Laminated on to the dimpled sheet, the layer of rot-proof geotextile out fine-grained soil particles, thus protecting the system of ducts formed by the dimples from being clogged up by sludge. This permits water to flow unhindered downwards to the perforated drainage pipe.
 
Delta-NP-Drain    
 
is a protection and drainage system for compression-resistant surfaces.  
is a two-way dimpled sheet made from special high-density PE with a fused-on PP geotextile. A compact system that may be applied quickly straight from the roll.  
is made exclusively of branded polyethylene. Containing no recycled material, it is itself fully recyclable.  
resists degradation in soil and is non-polluting for drinking water.  
forms a system of ventilation ducts between the foundation wall and the dimples which keeps the wall dry and provides additional heat insulation.  
features a drainage capacity that can handle twice the maximum amount of water that is likely to occur under unfavourable soil conditions.  
is highly compression-resistant.  
can be easily laid around corners and projections thanks to its elongation at break of more than 50%.  
conforms to DIN 18 195, DIN 4095, and Eco-standard 2209.  
features a material life of no less than 25 years when installed
