Your drainpipes are clogged – why?

Traditional drainpipes function on the basis of utilizing filters. On average 90 % of their efficiency disappears within 3 years from installation. The pipes silt up and become sludged. The pipes also become clogged by roots and the iron levels of the ground.  Dry drainpipes do not always mean a well-functioning system. A problem can also be geotextile filters clogged by terrestrial fine particles. Regardless of application a filter is always a temporary solution. If drainpipes do not function properly it can at worst mean moist conditions in the building leading to problems with damp and mould.


TehoDrain drainpipes do not need a geotextile filtering system to work. The fine particles in the french drain envelope are separated in the pipe by the gravity separation function. For this reason TehoDrain is non-clogging and maintenance-free.
