RIDUR concrete system shafts

The RIDUR system manholes are characterized by quick installation – they can be moved up to 30 % faster than conventional manhole systems. The manhole bases have a plastic manhole channel set in concrete, which offers exceptional durability and is resistant to aggressive wastewater. On request, the manholes are available in two attractive colors, allowing for visual differentiation in separation systems. Our monolithic concrete cones and manhole rings are available in standard heights of up to 2.1 m – either in one piece or made to measure. Each manhole is equipped with a seal set in concrete and threaded sleeves set in concrete for conductor installation. We also offer flexible adjustment of the manhole cover height thanks to our infinitely adjustable telescope, which allows heights of 0 to 30 cm and an inclination adjustment of up to 10°. We are happy to supply the appropriate ladders either separately or pre-assembled.
