Research done. Gotta get fancy with my form work. And not make the mistake of underestimating how heavy concrete is again. Will update the design and pop a few render up. Ta.

I agree the joint is not the strongest. However with the mass above, I can't see it moving. With the DPC painted on slab and up wall in one go, it would be a continuous membrane? I've nabbed the below off (dare I say it) B&Q liquid DPM as an example: If your concern is with water tracking...

Unfortunately, I'm going down from an existing 3m wide workshop to a 2.64m wide workshop due to available pace so I'm desperate to preserve every cm I can. I'm hard up against the fence posts (minus 20mm to get a finger in) and 850mm from the house wall (needed for access). So a thin slurry and...

So, the patch of land I've already mostly excavated is already well below grade. I've spend the last 12 inches chipping through rock, stones and clay. So I would likely be good just compacting hardcore on top and adding some trenches. Single skin. Blockwork rendered outside and painted. The...

Cool. Thanks the the input Mrs Ten. However.... Constraining hardcore?

No regs as below 15m3. Single story permitted development. No plumbing. Insulated roof. Within a meter of house and boundary though.

It's for a workshop with a few heavy machine tools. Two walls will be holding back 600mm grade increase of highly loaded land. As such, dpc will be 600mm up on one side and one end. Then one block up the rest of it. I am having to dig this by hand due to access and budget, so trenching is...

From the NHBC website, this is their guidance for garage foundations: I plan on using this plus some mesh as my new workshop base. Likely omitting any DPM as I'll be paining a liquid DPM over floor and up to a high DPC due to retaining walls. My question, is how are you supposed to compact...

In my very early days of DIY brick laying, I built a block work retaining wall. I made the pointing look good, but ended up smudging the (too thin) mortar into the block work texture around the joints, filling and smoothing out the irregularities. 15 years later, the untainted block work looks...

Ohhhhhh, thanks! I'm border line on this. maximum external dimensions I can manage are 5.88 x 2.72, so 15.99 (and I do want this as big as I can get) - but will be well within 15m internal floor area. That said, I'm going to be welding and grinding in there, so block work offers a desirable...

Thanks all for your ideas & advice. MrRusty, I like the idea of the timber and steel, but as 1) I'm close to the boundary so I need to be 'substantially non-combustible' and 2) I will be wanting to bolt a lot to the walls and possibly put in some form of gantry crane. so the added mass of the...

I have the below horrible north facing side of my garden adjacent to a carriageway. It's dim and gets about 2 hours of sun a day. Elsewhere I have a brick built workshop. The elsewhere is literally the best sun trap you can imagine and we would like to make it a more family oriented space...

Neighbors have exposed my garage foundation extending their driveway to the boundary. Not convinced they'll be able to cover it when laying the final surface. How does this stack up regulations wise?

Patio base laid and ready for install. Slow but getting there.

- Figured that was the case... Damn messy builders. - Oh, it most definitely IS channelling water down into the foundation trench (especially now I've removed the concrete pathway). I just don't know if it's best to: A) Try and keep as much muck out as possible to allow the channelling of...

So, on the left of this image, behind the spade and fork where I've busted through the concrete and shoved some geo-fabric to stop soil falling down is the area in question. Will get a picture of the actual gap tonight (if I can) Once I took up the concrete slab/patio/path thing, I found...

so, it's actually 6x2x1m now :) But that's just the pool (y). Before I even get there I've got another 10-12tons to dig out just to level the area :rolleyes:. Plan was to use Concrete Masonry Units (CMUs), or as you call them hollow blocks, for the pool. Mesh reinforced slab with protruding...

I've been excavating for a new patio that isn't flush with the DPC and have found that the foundation trench of our extension is back filled with old bricks and it *looks* like it may be designed as a soakaway. The foundation blocks are not mortared on their vertical edges and the cavity does...

Well, after digging out about a ton of soil, I finally reached my finished level. So with grab bag in place, I'm now moving soil to its end location, not a temporary place. Getting there... It should hopefully be a case of dig out a square meter into one grab bag so I can put another grab...
