Laying concrete on earth…

Next door neighbours are having an extension done in the process they have had to build us a new utility building and small patch of patio with concrete.

Today I asked the builder what he would charge to concrete 2.5m x 3.5m (patch of grass) so as to match the new bit of patio they had to do, he reckons about £300/£350 he will dig down 3 to 4 inches and lay the concrete on the earth and use the unwanted soil next door for their new patio (add height).

I thought you had to but some sort of rubble down before the concrete, he reckons its fine for such a small area as there wont be any weight on it…

Thoughts ? being taken for a ride ?

Personally I’d be putting down 75-100mm of crush n’ run, compacting it with a wacker and then pouring the concrete.

Price sounds about right for the concrete, £100 ish for the first cube and then about £45 to £60 per cube after that

that was the price quoted including laying it

I’ve laid a shed base using 3″ of screed on top of a weed proof membrane, on top of bare earth. Lasted 10+ years before I moved the shed to built the workshop.

Remember, laying a shed is like laying a bloke. Do it right the first time and you can walk over it for years.

I think it depends up one the earth you’ve got. If its clay and firm I think you’ll be ok laying it straight on.

i dug down 40cm this eve after the earth is clay (north london clay !)

As Steve-b77

I would remove vegetable matter and put down an compact 75-100mm of Type 1(£34+VAT for a Maxi bag). Remove any soft spots.

laying on top of subsoil should be ok, especially if its clay. on top of earth not so much.

we havent been in our garden the whole summer most of our patio was broken up to make way for foundations…so in exchange for all this we got a new utility building (as they knocked the old one down) patio and full building rights off the new party wall which is transferable to the new owners should we move I tbh I could have done without all the stress !

and will someone think of the children been locked up all summer with no garden ! 😆
