Skeletank High Performance Diffuser Conduits (HPDC) are used for the efficient diffusion of collected surface water runoff into permeable aggregates*. This technique can be utilised in conjunction with both pervious and impervious surfacings.

Skeletank HPDC units are installed within the pavement construction zone as a sub-base replacement system and are fully compliant with BS7533-13:2009, ‘Pavements constructed with clay,natural stone or concrete pavers’.

The Skeletank HPDC system is particularly useful where there are ground problems, such as high groundwater levels, contamination or shallow rock layers.

Each Skeletank HPDC module is encapsulated by a 2mm mesh, which provides an excellent open surface area, allowing collected surface water runoff to easily flow into surrounding aggregate.

Each SELH02001 module also has a pre-formed 110mm diameter socket, allowing efficient connection to standard PVC-u underground pipework.

*When using permeable aggregate for water storage we recommend Bardon Sudsagg or similar.
