1:15 marked out 100metres more? just how big is ya garden :D Nice video series so far though, am liking it, big thumbs up

😂 I meant millimetres! How did I miss that one? Thanks 🙏 I appreciate it

Just a quick tip for squaring off a large area like this. Instead of using a framing square, measure the diagonal corners for a more reliable square. Movement in timber can give the impression the area is square when it isn’t 👍

You put the timber frame on top of the hardcore but your very lovely info-diagram indicates that the frame should placed on top of the sand layer with both sand and hardcore layers extending out beneath it to avoid areas of unsupported concrete. Am I being too picky? Is the 2" sand layer so thin and liable to be unstable it gives little support to the concrete when the frame is taken away and the real support comes from the hardcore beneath it?

The sand is there to protect the damp proof membrane, so whether it goes under the frame or not doesn't matter. Also it's not 2 inches of sand, but 25mm. The full professional plans are now available on my website by the way if you wanted to check them out.

great progress Jack. Really well explained and thought out. Where were you 12 months ago when I was making bad choices lol.

Great video. Just one thing though (as a former civil engineer) is that I don’t recommend leaving out the mesh on a slab that big. Concrete shrinks as it dries and the mesh is there to stop the cracks from getting too wide.

Thanks for pointing that out. It’s good to know I’m on the right track from someone who’s actually qualified 😂

And if you're not going deep enough to avoid seasonal ground movements & settlement, then it needs to be designed as a concrete raft, with two layers of mesh are essential to resist tensile forces to either the top or bottom of the slab. In connection with which it should have edge thickenings with rebar in, to avoid the point loading from the walls shearing off the concrete.

@@Benzknees you only need 2 layers of mesh if the slab is not going to be fully supported by the ground, for example like when building over an old septic tank that could still be settling. I don't think shear would be a problem for this shed, but I would have put in a bit of an edge thickening myself.

@@AndrewEddie - Any foundation on clay can move seasonally unless it's set at the appropriate depth for the plasticity index. Considerably deeper if there's trees nearby. I saw lots of cracked & sunken slabs & footings due to differential movement of such ground. Designing a slab as a raft, capable of resisting tensile forces in both directions, largely obviates this possibility.

@@Benzknees yep, I'm very familiar with building in clays with crazy shrinkage values.

@JasonSmith-uk7zh Ай бұрын

Could of not used the mesh and ordered fibre concrete I think it's £30 per cubic metre more but well worth it. A lot less hassle and it's very strong I did my 24ftx12ft x 6inch base 14 years ago not a crack and a good finish👍

If you had measured diagonally both ways it would show square, checking long timbers with a tiny framing square isn't good enough, also its a lot easier to start putting concrete at the back of the space so you dont have to push heavy barrows over wet concrete

I did this too, I think it was only 5mm out which is basically bang on considering the size

I’m digging my garden over the last 2 weeks I’m at the 3ed skip to fill with soil which brings my cost to £720 already…

@sumeraybuilds 4 ай бұрын

Yeah I was very lucky to have the option to use the soil I removed, glad it was mostly topsoil too! It'll be worth it once you're done!

Hi , really cool footage and tips. So base is perfectly level everywhere ? I've heard base should have some fall for rain otherwise water may stay in one place and make moisture?

@sumeraybuilds 4 ай бұрын

Thanks 🙏 yes it’s perfectly level because I’m using it as the floor to the workshop. If you’re building a timber floor on top then I think you should have a slight fall on it to let water run off.
