The Rigofill ST system features universal components for infiltration, retention and storage of stormwater runoff. It is easy to install, camera-accessible and space-saving.
The stackability of the Rigofill ST blocks allows for storing them even in confined construction space with minimum space requirements outside or inside the excavation pit. Its space-saving storage close to the point of installation, its extra low weight and the multifunctional connections allow for quick, easy and reasonably priced installations.
The Rigofill ST full bock provides a storage volume of 406 litres with a gross volume of 422 litres. With > 96 % storage volume it stores three times as much water as gravel swales – the ideal alternative to gravel swales which require much space and extensive excavation.
The unique transparent and cross-shaped design of the inspection tunnel of the Rigofill ST block makes the entire inside of the block visible.
The Rigofill ST full block consists of two half elements to be installed on site and has a void ratio of > 96 %.
The cross-shaped inspection tunnel in the storage/infiltration unit has been designed for the use of automotive dollies. This allows for full inspection of the effective drainage surface and the entire system volume with all statically relevant bearing-type fixtures.
Installation under trafficked areas (HGV 60) and at great depths is possible.
