Permavoid (85 and 150mm)
Modular cells that link together to form an interlocking raft of exceptional high compressive and tensile strength.
Permavoid System Components
The Permavoid System comprises of a number of components which may be utilised within a SuDS design:
Modular cells that link together to form an interlocking raft of exceptional high compressive and tensile strength.
A linear treatment system that combines run-off collection, silt and effluent interception and water treatment functions.
High strength geocellular unit containing a low density, oil treating, geosynthetic floating mat.
A non-woven dimpled, needle-punched geotextile designed for hydrocarbon pollution treatment.
An impermeable membrane for wrapping around Permavoid structures to form watertight tanks.
Fully interlocking tapered tie connections to securely link Permavoid cells together horizontally in a single structure and to transfer tensile loads.
Comprises of a low density, oil treating geosynthetic floating mat for use with the Polystorm range of modular geocellular units.
A combined run-off collection, silt/oil interceptor and treatment system used with road/yard gullies.
A heavy duty, non-woven, polypropylene, geotextile designed to protect and separate Permavoid geocellular layers.
A prefabricated orifice plate flow control unit, incorporating a removable filter to protect the orifice.
Permavoid units encapsulated with a 2mm mesh fabric to diffuse the collected run-off into the surrounding granular sub-base.
A range of Spigot and Saddle Connectors allowing piped connection to the Permavoid structure.
A heavy duty, non-woven geotextile formulated to provide passive irrigation to soft and landscaped areas.
Enabling passive irrigation via capillary action, for use on roof gardens, green roofs, sports pitches and arenas.
