When I had my conservatory built last year, the builders had to go down
1.4 metres with the trench to hit something solid to build on. A Readymix lorry delivered the base and 6 guys barrowed it into the back garden.My next door neighbour is having one built (different builder, and at much lower cost for a slightly smaller conservatory). There was one guy hand digging the trench - he started yesterday morning. Don't know how far down he went, but there wasn't anything like as much earth in the skip as when mine was dug - indeed, my builders had to get a second skip because they filled the first one up in a day,
This morning, when I went out (about 8.30), they were just starting to mix some concrete in a small mixer out on the front lawn to start pouring the concrete into the trench. By the time I cam back (about 2 pm) there's a three foot high brick wall already built
My concerns are
a) did they dig deep enough b) have they waited long enough before building the brick on the concrete
(He's away on business, and his wife is out all day at work, and I'm guessing neither of them has much of a clue of the right way to go about it, any more than I do really)
