Drive / Gravel / Edging

Acc72

Hi All,


I currently have a concrete drive (this was laid in parts over time and is quite unsightly) and am looking at freshening this up with the help of golden gravel.


However, if I just put the gravel on the top then it will go all over the pavement etc - as has happened with other drives in the street.


I was thinking of putting down some edging stones to contain the gravel within the drive, however how do I do this as it will be on top of an existing concrete base - do I simply concrete these on top ? - will they stick ?


Alternatively, any other suggestions would be most welcome !

Won't the level be a bit awry if you top the concrete base up to add 75mm or so?

Personally, the only way to do this properly is to hire a company in to remove the concrete, level the remaining base and top it up before infilling with your gravel of choice. Edging stones will be mortared in place...chances are if they're stuck down on the concrete they'll come loose before too long. if they get any impacts.

Dig up the concrete and start again or apply a resin bonded aggregate top coat if the concrete is not badly damaged.

other than ripping all or some up you will have a lip if currently level to the pavement
slant/wedge curbing seems to be the ones to get a raised lip that would retain gravel and give a slope to drive up.
if you can't get preformed the right rise you could cut out and reconcrete one in the size you need to act as a retainer

you might get away with a strip of plastic gravel retainers bolted down to stop them moving either along the street edge or as drive strips for the wheels again probably best to take out the existing concrete and use them to give a staggered rise.

around £10 sqm for gravel retaining squares.

Gravel isn't suitable for laying over a solid surface such as concrete as it isn't able to bed into anything. You need to either bond the gravel to the concrete or pull the concrete up and provide a proper base for the gravel.

You need what is called 'tar and shingle'

A layer of hot tar is sprayed over the existing concrete and then the shingle/gravel is spread over this whilst the tar is still hot.

Its not too expensive to do but look for a reputable company.
