U Drain

Open U-shaped channels that carry larger volumes of surface water along roads, estates and work sites.

Product Overview

The workhorse of surface drainage

The open U section is easy to inspect and clean, and precast units go into a prepared trench quickly. That makes U drains a common choice for roadside and estate drainage.

Our U drains are mesh-reinforced and come in a range of widths and depths, from estate drains to larger roadside channels. Full sizes are listed in the catalogue.
