Drainage Systems

DRAINFIX® TWIN double tunnel system

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.

DRAINFIX TWIN are combinable infiltration elements with particularly large storage capacity. This large available volume makes it possible to collect large quantities of water. Subsequently, the water will be slowly released to the surrounding soil. Compared to conventional gravel-filled infiltration structures, site requirements and excavation are reduced by 2/3. The surface areas remain fully usable for other purposes.

Application areas

Collecting and storing stormwater for infiltration from sealed ground surfaces in private and public areas with low traffic volumes.

Transport Advantage

One Euro pallet will carry 32 stacked elements, which corresponds to approx. 8.1 m storage volume. It means favourable transport costs and small space requirements during storage
