I'm putting up a new house and would like a cattle grid at the top of the driveway, partly to avoid the need for a gate but mainly to intercept water that will run off the public road and wash away all my gravel.
I'm amazed at the cost of these things though- best part of £2k for a new one. Ouch.
Wondering if it would be practical to build one, using a blockwork foundation and galvanised steel pipes or RSJs. Anybody done this?
