The Weholite system provides solutions for all sewerage and storm-water systems, including Manholes, Valve Chambers, Inspection chambers, culverts etc.
Unlike traditional concrete manholes, they do not require any concrete surround or rocker pipes, making them easier to install and saving you time and money in the process.
Weholite manholes are ready to use immediately, without any additional preparation or setup. This significantly reduces the installation time and costs associated with traditional manholes.
In addition to our manholes, we also offer prefabricated valve chambers that can be manufactured with inner diameters ranging from 350mm to 3000mm. This means that you can choose the size that best suits your needs, making it easier to find the perfect solution for your specific needs.
