Anyone ever laid a cobblelock driveway?

Yes

My neighbours have a cobblelock driveway, so yes, there is definitely one person in the world who has laid a cobblelock driveway. Next question...

I once ate cobble in my driveway when I was locked....does that help at all?



there are a billion tutorials on youtube, but unless you have all the bits already you arent going to be doing this anytime soon...

Just looking for some advice on neat way to level each section ie, hardcore base, then sand

Materials cost a lot and this is something you'll be looking at for decades. I'd not even consider doing it myself.

Cobblelock driveway is nice if its done right and properly maintained. Like practically everything else you could do it yourself as long as you are reasonably competent and have the right equipment for the job. Too often though you see uneven and badly sunken cobblelock or cobblelock ruined with lichen. This sort of thing looks horrendous in my opinion.

I’ve been renting house for last 3 years. Last summer I power washed the cobblelock driveway. Although some water did pool in an uneven part, it turned out well & landlord was impressed.

However, now in the pool location, 4 bricks have sunk, it’s on a slope so it looks poor and is a bit dangerous. I’ve had a car sitting idle on top of slope since November so suspect it might be pushing bricks down.

Could the power washer have washed away the sand or car have shifted the bricks? I don’t want to pay for a new drive for landlord .

That's why i never use just sand under cobblestones or paving slabs. Always best to use sand and cement or dry mix floor screed works good too. The extra water from the power washing has either moved the sand around underneath or has washed away altogether.

I don't if anyone is familiar with Clondalkin but they had cobblestoned the road in the early naughties going through the village, this happened there too. It was awful!

cobblestone doesnt work for any length of time under traffic, regardless of the sub surface or how good a job install.

Its sole purpose is pedestrian traffic or driveway. And even a driveway can be destroyed if a Skip Truck rocks up.

Thats easily repaired but taking up the bricks and a few more around , levelling the base again and replacing the bricks.

I reckon he used sand, though it's hard to tell. I did remove the bricks, put some gravel under & set them again but it's not right. I'd say even if the power washer didnt do it, the rain did.

I would use the professionals, I bought a house with one, it was done wrong from day 1 and had a big section which would sink and create a big pool of water

I took it up 2-3 times and put down fresh sand but still kept going back....

It’s someone else’s problem now :-)

Sand has to be used though, it is to sort out micro-adjustment leveling. you cant avoid the sand, but it also cant be too deep.

Thanks listermint,

Is it atypical to use grout or is there similar product for cobblelock? He’s just left gaps which lets moisture get through easily.

You shouldn't see any gaps tbh the should be micrometers. Gaps would have sand brushed into them.
