QuadroControl ST-B is an inspection shaft that can be integrated in Rigofill ST-B polypropylene storage/infiltration systems. It is square with a base of 800 x 800 mm and can be used in any position of the block pattern. Its height results from the number of layers of the connected storage/infiltration unit. QuadroControl ST-B allows comfortable access to the inspection tunnel from above. High-performance inspection and flushing technology can easily be inserted into the inspection tunnel. The shaft is integrated in the storage/infiltration unit and grows layer by layer as construction progresses. QuadroControl ST-B is delivered with all required components and will be assembled on site. The outside is sealed with Rigofill ST-B side wall lattices.
