Rigofill® ST-B block/half block
The heavy-duty Rigofill ST-B storage/infiltration unit has a base of 800 x 800 mm and a height of 660 mm. The block is made of polypropylene (PP).
The Rigofill ST-B full block consists of two half elements to be installed on site and has a void ratio of > 96 %. The Rigofill ST-B half block consists of only one half element, which must be assembled with a roof slab on site. 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. In combination with QuadroControl ST-B, Rigofill ST-B storage/infiltration systems have been designed for professional final acceptance inspection and repeated inspection. Installation under trafficked areas (HGV 30) and at great depths is possible.
NB! Follow the Rigofill ST-B installation manual!
