POLYNEX access shafts are the long term choice for your underground assets.
Manholes are integral part of sewerage and drainage systems. They are used to maintain, repair and clean such infrastructure, and play a key role in the service of thousands of kilometres of pipe networks. Manholes can be used to change flow directions, adjust falls and profiles, and establish sewerage system joining.
Spiral-wound POLYNEX High-Density Polyethylene manholes (HDPE) are formed using a unique double-wall ‘i’beam profiling, resulting in compression strengths up to 8kN.m2. Resistant to fatigue and corrosion, HDPE manholes has an estimated asset life of 100 years. Pipe size range from DN800 to DN3000.
A moulded base is permanently fixed to the base, and an outlet and several inlets stubs are robotically cut and welded into position – to suit your exact requirements for diameter, class, angle and height.
Supplied locally, POLYNEX HDPE access shfts are the superior choice for waste water and sewerage applications – the long-term choice for your underground assets.
