Motorway Slot Drainage

Product Overview

We provide bespoke Pipex Thermoplastic outfall chambers and linear drain formers where obstructions (such as existing manholes, pipework etc.) restrict the use of slip forming slot drainage methods.

Our bespoke thermoplastic drainage chambers for Smart Motorway slot drains are designed to interface with concrete slip forming drainage, ensuring integrity of the slot drain during application.

Lightweight chambers and hexagonal and pipe slot drainage, access boxes and couplers provide a solution where slip forming is not possible. We deliver to site in prefabricated units minimising the overall installation programme schedule.
