Flat Capiphon Belts

Capiphon is available as 10m rolls of 100mm wide belt.   This is the standard Capiphon product which can be used in a variety of applications, horizontally, vertically or on any angle.  It can be cut to length to suit.

Flat Capiphon also comes as 5.8m rolls suitable for 6m lengths of PVC pipe but you can cut it to any length. (see the guidelines for fabrication). 

It is ideal for:


Drainage under lawns, pavers, and slabs

Placing under lawns, pavers, concrete slabs, and other horizontal (or almost horizontal) structures.  It is usually inserted into a collector pipe 10-20cm below the belt to create extra syphoning pressure.  This is the most effective  method of using Capiphon because the flow rate increases with "head" and the syphoning effect transfers the "head" of the drop to add to the "head" above the belt.  Capiphon Belt is usually spaced between, say, 1.2m and 4m apart, depending on the expected amount of water.

Retaining Wall Drainage

Running down retaining walls and behind basement walls into a collector pipe. Spacing between strips of belt can be from 1.2m up to, say, 3m depending on the expected volume and source of water, and are run up to the surface.  Backfilling with a 10cm thick "sandwich" of washed, coarse sand.  See the Case Study "Waterproofing on a Boundary".

Creating a cut-off (intercept) drain

Using small strips inserted vertically into a collector pipe to create an intercept (cut-off) drain. An intercept drain is simply a narrow trench with strips of Capiphon Belt running down into a PVC collector pipe at the bottom of the trench which is then backfilled with washed coarse sand.  It is very much like a retaining wall drain - without the retaining wall.

Intercept drains are the most cost-effective way of draining lawns and stopping water coming from neighbouring properties.  It is also very cost- effective for agricultural drainage.  Why is it so cost-effective?  Because only a small length of belt - say 500mm - is required for every 1-2 metres.

Drainage in narrow spaces

Using on its edge against a wall to provide drainage in very narrow spaces

Capiphon Belt is available as 

  • 100 mm (most commonly used).
  • Approximately 6m rolls of 25 mm,or 95mm wide.
  • Other lengths and/or widths can be especially cut. Please contact us for pricing

Capiphon Fabricated Pipe Products

Capiphon Pipes can be constructed on site. The Belt is available as 5.8m rolls suitable for 6m lengths of PVC pipe but you can cut it to any length. (see the guidelines for fabrication). Collector/connectors are available for each pipe size.

Capiphon pipe is ideal for:

Limited Spaces

Placing behind retaining walls, basement walls, and under buildings especially where working space is limited. It can be used in conjunction with strips of belt if circumstances warrant it.

In Drains

Intercept drains where required for special purposes such as racecourses or other equestrian areas where very narrow trenches are required to avoid the problem of the horses hooves sinking into the trench..

Comes in 3 widths:

Capiphon Pipes can also be constructed on site. The Belt is available as 5.8m rolls suitable for 6m lengths of PVC pipe but you can cut it to any length. (see the guidelines for fabrication)

DWV PVC Collectors for Capiphon Pipe construction

The collectors are made from 200mm of the same PVC pipe that the Capiphon Belt is wrapped around. They therefore come in 3 sizes:

  • 50mm DWV pipe collector
  • 40mm DWV pipe collector
  • 25mm DWV pipe collector
