Belt

Capiphon™ is a drainage material made from a special formulation of PVC that remains flexible and is long lasting. Capiphon™ has a series of grooves running down its length. The grooves are omega shaped with an internal diameter of one millimetre. The opening to the grooves is approximately 0.3 mm.

Water exists in a soil within the pores between the soil particles. The openings of the grooves of the Capiphon belt are similar in size to the pores within the soil, and water moves into the grooves by capillary action or “wicking”. The water held within them acts as a capillary straw.

When the belt is below the water table, or when the belt is on a slope (usually 1-2%), the critical capillary head is exceeded and causes the capillary straws within the grooves to move down the belt. The movement of the capillary straw within the grooves creates a negative pressure that sucks up water from the soil. This siphoning effect continues to drain the soil for as long as there is an effective capillary straw within the soil.–

The Capiphon belt can be laid in a variety of ways and in conjunction with the Drain tube creates a unique system that is far more effective than conventional drainage systems.

It is easy to cut to any length or width with scissors or a knife and can be made fit to any problem area.
