Laying kerbing onto concrete base

[do_it_yourself]

First post so please be gentle!

I'm about to lay roadside kerbs at the edge of my verge to stop vehicle damage (Its been approved by roads sevice).

I have a problem in that I cant dig the road to get a concrete base below th e kerbing. So I'm just wondering would the ST4 mix for haunching be okay for the back of the kerb only, or should I have a thin base below kerb to raod surface?

My base is basically road. I'm planning to kerb around the outside verge, so behind the kerb will be soil with grass.

Thanks
MM

are you sure of this??
AFAIK only council approved contractors can do this
normally you need 150mm of lean mix underneath kerbs at least as well as the haunching
a picture would help

I'm very confused, as LLL is - this is a job only for an approved contractor.

Are you sure they have given permission?

yes, they even supplied the kerbing.

its to stop people driving on my verge, they marked a line where 'highway' ends and my verge starts.

I guess theyre civil service, and dont want to spend money on their own contractors!

To get the 150mm base I will need to drill the road.
I thought it odd to be honest but if they insist in not helping me then I'm happy to do it myself.

I've heard of this where over the years and many relaying contracts the road surface has encroached onto private property.

Even if it is allowable you cannot lay kerbs onto tarmac. Whatever you put in front or behind will not prevent them from coming loose. Bad practise and potentially hazardous. Add to that the risk involved in a layman working kerbs (specially handling and lifting regs from the elf executive) and the temporary barriers and signage, etc., this is a no-no.

Why not embed rockery rocks into the soft verge? Much easier, safer and cheaper. Or a row of short but stout posts? That'd keep the buggers off.

I had that mate, until someone in a sports car decided to use the country lane as a race track, hit my stones then complained to roads service.

Apparently its not exactly legal to put stones on your verge in case of 'emergency situations'. It was roads service idea to kerb around it and stop people from going up onto it.

Its their opinion that kerbings the best solution.

I was happy with a picket fence, but hey if theyre providing the materials.

In Ireland, the county council will often provide landowners with permission and a few kerbs to 'improve' their own threshold - it's NOT the same in Britain or in NI.

Anyway, the kerbs really do need to have a concrete bed as well as haunching: one without the other is useless.

When we've laid kerbs in Ireland, we always use a concrete bed, but it needs the very edge of the road to be excavated, and this occasionally disturbs the road surface. However, as we are working for the county council, they can effect a repair once the kerb line is in place. This is probably not an option for you.

Which means that the only realistic option is to set the kerbs back from the actual edge by, say 100-150mm. less than ideal, but unless CoCo are prepared to repair the road surface, you don't really have an option.

Hello Tony,

I'm in that grey area called Northern Ireland. DOE Roads Service are alwys moaning about not having budgets for this, that. (Although they can pay a guy up the road £10million punds for about 6 acres of land that a major road will go through in 10 years time, and that was 2 years ago!

The roads service have given me the go ahead, they know the verge well and I'm sure they do realise I will be disturbing the road to dig a base for the kerbing.

Theyre taking the p*ss if they expect me to just lay it on the road, without disturbing it.
