Manufactured in high strength polypropylene, offering stiffness well in excess of other plastic products. The range includes couplings, seals, bends, junctions and specialist fabrications.
The Ridgisewer range also includes junctions to connect to the Polysewer system. Ridgidrain manholes and catchpits are used in a wide range of applications including railway drainage, highway drainage and oil containment systems. They can be manufactured to standard designs or to customer specifications at our fabrications department.
