“We needed a culvert that wouldn’t float as we were installing it in running water on agricultural land. It was important to us that it wouldn’t bend, it was easy to install and that it would last. That’s why we chose galvanised steel pipes. It’s much more robust than plastic and provided a more cost effective solution. Cotterills’ service was fantastic and I would definitely use them again. They kept us up-to-date with delivery times and took the time and effort to make sure the delivery was carefully managed from start to finish. What’s more their courteous delivery driver helped offload the pipes safely for us.”

"We chose to go with the galvanised steel pipe to divert a watercourse because it was much easier to use than HDPE. It’s lighter and easier to maneuver into position. The service from Cotterills was excellent. The turnaround was quick from order to delivery and they let me know exactly when the pipe would arrive."
