Hi all, I have just landed a contract for maintenance on a driveway shared by three properties, these house's are all well over £5M each, electric gates, camera etc. You get the idea of the area.
I have been working for one of the house's for around three years so clients are happy with me to do whatever I say (within reason)
Anyway part of this driveway is fairly steep, curving around. It has a bank on the outside edge which is always slipping over down the driveway, especially with heavy rain & leads to silt etc. flooding down to the bottom house. See images.
I have been asked to come up with an idea/ cost for raising up the kerb edge to retain the bank, I paced it out & it's around 55metres that needs retaining! The existing kerbstones have around 100mm depth of concrete on the rear edge.
We have discussed things like Everedge but because of the existing concrete this would be sited quite a way back from the existing meaning a gap between the two.
Also sleepers, but these would look out of place, would also need a footing & pinning behind.
Another idea is to set a second set of kerbstones back, like a step behind the existing. Again these would need a footing or possibly just mortaring down?
Can anyone else come up with anything that I am missing or some other idea.
Cheers Neil

Could you use Everedge, dig out the soil in between the Everedge and the kerb and fill with a decorative gravel?
Thanks Darren, the everedge would need to be at least 100mm back because of the concrete backing on the kerbs. & to then infill with gravel I think would be causing another problem as in some places there is no depth to hold the gravel.
Hi Neil,
you can get a 125mm profile in Everedge I think it might be slightly thicker to for more strength.
I would have thought that the easiest and cheapest way to do it would be to cement another layer of curb edges of some description directly on top of the existing ones, like building a very low wall. The existing curb stones are already well set in with strong foundations, so would be a good base to build on. You would probably only need one layer in any case.
You could even stagger the joints like in a brick wall or maybe use shorter blocks, to make it decorative. It would save either removing existing concrete foundations or digging out and making new ones further back.
You could maybe set the new layer about one inch in from the front edge of the existing curb, to create a detail.
I would second vic , best and simplest way
An estate where i was employed had an almost identical drive , with identical kerb .
The low kerb carried away water successfully when it rained , the water also carried away a fair amount of debris from further up the slope . That problem wont go away no matter how high you build the kerb ,
one reason they liked the low kerb was to stop expensive vehicles hitting something solid and getting damaged during the winter months when the drive froze and came skidding down ,
to the left where the shrubs are was a field which we turned into a lawn which we edged and inevitably the same problem occurred erroision and silt started to build up on the drive .The solution was to build a rockery from boulders behind the shrubs and in front of the edge which couldn't be seen from the drive .
I always remember the drive had to be kept immaculate daily , it was a constant battle no sooner had you cleared it it was full of debris again , a losing battle and complete waste of time but a clean drive was aesthetically pleasing and gave visitors the first impression .
Yes thanks Vic, this is what I am thinking more & more. I would use a brick bond if done this way as well.
Why not take it back 200mm run an edge through then Garvel in between edging and kurb race
Could you run some form of v-ditch or drain off the driveway to intercept run-off. This would just need cleared annually. Inexpensive and very effective. Hard to see from photos whether this would function effectively or be aesthetically acceptable.
Just a thought. If building up to intercept isn't an option, cut down to create a channel of some description.
Thanks Neil, there is quite a camber on the drive which sort of runs the wrong way so a channel wouldn't really help. It was suggested a while ago about putting raised rumble strips in to do the same. Out of the pictures on bottom rignt is a driveway then just beyond this two drains which constantly silt up & flood. Especially with the heavy rain we had over the winter, thats why looking at stopping the slippage.
Cheers for the idea though.
