As the leading name in the manufacture and fabrication of full HDPE pipe solutions, Marley offers custom fabricated HDPE manholes for a variety of applications, manufactured from a combination of high quality solid-wall and structured wall pipe.
HDPE has long been considered a reliable alternative to manholes that are produced from concrete, brick and mortar, or fibre cement owing to its light weight, ease-of-installation, and resistance to corrosion and abrasion as well as a wide range of chemicals that would otherwise reduce the lifespan of traditional materials. As a result, Marley HDPE manholes are resistant to root ingress, preventing contamination to surrounding groundwater and providing a watertight structure that delivers an extended life expectancy.
Marley’s HDPE manholes are prefabricated, which eliminates the risk of deformation in the structure, however, the shaft configuration of the manhole can be also be adapted to accommodate any application separate from the full plastics system. HDPE ladders can also be fabricated inside the manhole upon request. Standard covers and frames are also available.
Marley HDPE manholes and fabricated fittings meet all of the testing and manufacturing requirements of each standard, guaranteeing quality in materials and workmanship. Marley also specialises in the design and fabrication of floats and pontoons to make up the full solution.
Projects that have been successfully completed using Marley’s HDPE manhole solution include DPW Sites GP, Waterkloof Airforce Base, Swartkops, Drakenstein Municipality, Buffalo City (PE), eThekwini, Ekurhuleni and Fraser Alexander (export).
Sewer & Stormwater Manholes:
Marley HDPE manholes offer many features and benefits for underground gravitational and pressure systems, including the inspection, maintenance, ventilation, cleaning and flushing of drains or sewers or for the changing of flow conditions (change of direction, change of pressure, change of water flow rate).
Manholes for Telecommunications:
Marley HDPE manholes are well-suited for installation in difficult terrains where there is limited space to work in, making them ideal for telecommunications and conduit systems.
