DRAINFIX BLOC is a polypropylene (PP) infiltration block with a very high storage capacity. The void ratio is more than 90 %. The system can be installed in areas with different load requirements – even in HGV-trafficked areas up to SLW 60. The modules have been tested structurally for different load conditions.


Decentralised infiltration facility in private and public areas with low traffic volumes. The elements used to fill the infiltration structure should be lightweight and easy to handle and offer maximum storage capacity for small space requirement. The material must be durable and strong. The surface area should remain usable.
