Weholite Manholes

Weholite manholes are flagship products that represent the very best of offsite build. This provides enhanced value when the whole project cost and the benefits that these products can bring, such as superior quality, programme reductions, consistency and sustainability, are taken into account.

The factory-built environment and modular technology ensure that the inherent and residual risks, in terms of cost, efficiency, health and safety and environmental aspects, borne of the complexity of traditional construction processes, are avoided. Weholite Modular has attained certification for DWI Regulation 31 Reference no DWI 56.4.513 “Approved for use in public water supplies” and is WRAS-approved.
