Just after some advice on a gas pipe.I am putting some footings in for a conservatory and came across a gas pipe (in plastic yellow so it must be gas) my problem is its not really far enough under the ground and will run straight through my footings, so what do i do with it?.Can i wrap it in something, bury it with concrete (i think not), sleeve it (in what).You probably get the idea so any input is welcome thanx
