Precast Concrete Headwalls - Visit our website

Our range of precast concrete headwalls are suitable for use with pipes, culverts and box culverts. The vast majority of SUDS drainage schemes utilise concrete headwalls in order to prevent erosion into watercourses such as rivers, ditches, swales and detention basins. It's worth noting that all of our precast concrete headwalls can be fitted with optional accessories if required, including handrails, gratings, ladders, flap valves and penstocks. If you'd like further information on this range, please feel free to visit the website. 

Sewers for Adoption (SFA) Headwalls - Visit our website

Sewers for Adoption (SFA) headwalls are manufactured and installed with specific guidelines in mind. We offer four different models and can accommodate pipe sizes up to 15000mm. Accuracy is key and all of the outfalls within this range are cast to suit the precise diameter and type of pipe being used. Furthermore, if customers are planning to add other components, we can cast fixings at the same time, e.g. gratings, flaps. valves. ladders etc. If you have any specific queries about our SFA headwalls, don't hesitate to get in touch. 

Flow Control & Flood Prevention - Visit our website

We offer an extensive range of products for the control and management of water, including flood prevention. These include, stop logs, penstocks and flap valves, just to name a few. It's worth noting that some of these components can be pre-fitted to the headwall units during the casting phase. Pre-installation saves time and effort and prevents any on-site issues which can occur during installation. The full range, including detailed technical information can be found on our website.

It's worth noting that the products themselves have been designed and manufactured with stability and longevity in mind, offering a high quality, reliable experience.
