Hi this is a first post for me.

I have dug all the topsoil down to approx 18'' in my 6x8m lawned front garden with a view to putting down MOT type 1 limestone scalpings (40mm-dust) then gravelling
But running along side an existing concrete slab drive I have found three service pipes, these\are:

* a black coated metal cable presumably the electricty approx 1.5'' diam

* an black alcathene water pipe

* a grey/yellow plastic pipe (gas??) about 1.5'' diam

All these run parallel from the street to the house. The soil is clay but is hard subsoil (albeit is a bit soggy at the moment). House was built in the 1950's.

My question is can i put the MOT down and compact it with a vibrating plate without damaging the services. And if not how best to protect them. Will cutting a plastic soil pipe in half and laying over the top do the trick?

Any help would be great, cheers

seneca,
Put a good covering of sand over the pipes, about 75mm should be adequate.

as stoneyboy says cover with sand but also lay warning tape ontop of it.you can buy it from your local builders merchant

Thanks guys, most helpful. Will get a grab bag and give it a covering before getting the MOT delivered. Cheers.
