Hi all, brain picking time again, I am going to build ( I HOPE ) a gravel driveway,I know all about getting a good solid base and laying a membrane ( not to sure where to place this ) but I keep getting conflicting information about putting a lean mix of concrete down as a finale base before the gravel goes down, I have seen some that have it and some that don't, one that has it is still looking good after 28 years.All ideas would be very welcome, Reg

Can I ask what the purpose of the concrete underneath the gravel is? Is this to hold the gravel in place (like resin-bound surfaces) or is it to act as a sub-base?
I'm asking because I reckon if you were to put a thin layer of gravel down over concrete it would be a very slippery surface (like ball-bearings on a wood floor) and the concrete would show through.
But, if you put a thick layer down over the concrete I can't see the benefit that concrete would have over a "traditional" layer of compacted hardcore.

Follow the guidance on the page and job's a goodun! Any 'conflicting advice' you have read about using a layer of lean mix of concrete under the gravel is wrong.DIYnot Local
