UPDATE #2 Forms builts, rebar tied in and dowels epoxy'd into the older slab Concrete poured, it was 150mm deep and took approx 3-4 hours by myself, I was definitely over thinking the process, hardest thing was remembering how many buckets of ballast I added to each mix 😂 Left the forms...

Hi all, I'm finally progressing on my build after getting LOTS of help from this forum on how to approach my build. I will first extend my current concrete base with a trench layout and will be following Mike's shed design (I'll be laying down concrete lintels and building from that) The...

Hi, im slightly confused, where does the closed cell matting get used in this?

Ive read the typical process of laying a concrete slab is Compacted hardcore > sharp sand > DPM > Concrete. How would you incorporate a DPM when extending a concrete slab though? Would you leave the face of the concrete slab that will be in contact with the new slab bare with no DPM (like this...

Thanks for these simple instructions, this is how I'll probably approach the task. Are you referring to the paving stones next to my concrete base? I really don't know Im afraid, but they are laid on 60mm of mortar it seems Concrete lintels, 100mm x 65mm. Ill be laying them down on the 100mm...

thankyou, this take some of the stress out of doing this for the first time 😄 Only reason I was thinking of shim was because I've never laid any brick before so I was thinking Ill take my time getting it all level with shims and then just pack out. But It would probably be quicker to just lay a...

This is what I was thinking too, the shims are just there to get the thing level, the full bed of mortar underneath does most of the heavy lifting

Its relieving to hear this so thankyou. Its so confusing coming at this with zero experience, I'm slowly starting to understand that there are many correct ways to achieve the same result, and for something like a shed there's a little more leeway. Thanks for the tip, plastic shims are much...

Yes thats perfect thankyou! For the hangars that secure from the top, would I need to somehow fill the small gap that the thickness of the hanger will raise the bottom plate of the wall by? Or is it negligible? Hi Fitz, thanks for this info, much appreciated, to answer your points (with a...

Agreed, a plastic bottom section is a good idea, thankyou! Thanks, i like the idea of an additional row of lintels but I'm dreading getting all these lintels level as I have part concrete base and part paving stones that these will be spanning across. All leveling will have to be done with...

Im clueless with all this haha, are you saying he'll be laughing because there's no such thing as non shrink grout? Steel/Slate shims and mortar it is then 😄

Im 6ft4 and want to give myself as much headroom as possible in the shed so I stop hitting my head. Raising the floor 150mm off my base would lose me too much. So I'm thinking of flipping a 100x65mm lintel on its shortest side and laying my floor joist on that. The floor would only be 65mm off...

Thankyou all for the info, ill see if I can get hold of some slate or steel shims and some non shrink grout.

ill see if i can find slate, steel seems like its much easier and cheaper to find though Im a complete beginner to this, what does point in mean? Would you want to completely pack out the gap under the lintel?

Hi all, have been searching through internet for videos on how to shim a lintel and can't find anything. Would appreciate any advice on how to do this. I'll be laying 1500mm long lintels in rows of 2 to span a total of 3000mm. 1800mm of the lintel will be on a concrete base and the remaining...

I understand what you're saying regarding load. So maybe I do not need to do anything then 🤷‍♂️. If I just build across the paving section would I just shim up the concrete lintels as much as possible to spread the load on the paving stones? What would be best to use for shims in that case? Or...

By pillars, do you mean something like my sketch below? Honestly, I'm looking for the easiest option to remove as little soil as possible. This will be a workshop with wood and metal working machines (probably the heaviest being a metal lathe (300kg). I can always place the heavier machines on...

Thanks for your input, im a bit confused by your suggestion. Ive seen the method of connecting new slab to old slab with epoxy and rebar. My plan was to lay a separate trench of concrete that would have the current paving slabs in between the trench and the old slab. How would you connect that...

Hi all, ive been busy reading up on the many great shed projects here! My current plan is to build a 4m x 1.8m shed. Ideally I'd like a 4mx3m shed. Now to save me digging up a large section of the garden (I don't have the budget for a skip and all that extra concrete. I was wondering if it...
