Choosing a culvert for a driveway or farm road

A culvert lets water pass under a driveway or road. If it is too small it blocks, the water backs up and the road washes out.

Start with the water. How much flows during heavy rain, and where does it come from? A larger catchment needs a larger diameter or more than one pipe.

Then think about the road. The pipe needs enough cover above it to carry the load of the vehicles that will drive over it, and a firm, level bed so the joints stay tight.

Because every site is different, send us the location, the road type and a few photos. We will advise on the diameter, the number of pipes and the length you need, and quote for supply and installation.
