Could you share these or PM across pls

Thats good to hear. Should last at least 3 builds then. Using our own timber or passing that on too? I have a fairly reliable source of used stock from a commercial site hoarding company. One standard gable here. ?Good, not interested in the catwalk brackets

Be good to hear all about these. I'm leaving 75mm around the perimeter which will be clear of UFH pipes to fix down into the slab. So @Russell griffiths how many zont units are you looking at and what's the price? Are you thinking that you would buy the lot. I give you 2/3rds purchase price on collection, @Alexphd1 then gives me 1/3rd purchase price when its his turn? After that @Alexphd1 could sell the lot and we split what's left 3 ways. Or we could donate to the Buildhub tool library! You never know you might need them again for your next project? Looking at the units I'd imagine the life expectancy isnt as long as their heavier steel cousins

Its my first time using ICF and the support of Logix is something I value. They will be on site for the first concrete pour. That said the zont system looks up to the job and might even be superior for my build. Ive been quoted hire of £6 per unit per week (maxed after 4 weeks) and need 62. Gulp! Timescale is tricky, I’m pouring my slab first week of October, then I’m waiting on finances and 6-8 week lead time on the Logix, it’s likely I could follow you and would need at the end of the year.

Hi @Russell griffiths, potentially I could be interested. My quoted hire charges are also significant, I will have to check with Logix that they would be happy for an alternative bracing system to be used. But yes could be a goer.

Colleague with knackered knees always had cold gel pads ready for break times. He swore that putting them behind leg instead of on the knee cap was much more effective.

Hi @RichS Apparently Lotusan is still the best product out there at the moment. I know a recent project came in at £50/m2 installed. Im still considering whether a traditional sand and cement render is the way to go for my ICF walls; I need my house to fit in with the C19th neighbours. My worry is acyclic renders look a bit too perfect and crisp. But sand and cement render could fail if too heavy and the mesh fixings aren't adequate. What product are you leaning towards?

Also do sealants and adhesives

Just a rookie question to check I'm entering my data correctly; is the internal floor area required in cell B21the footprint of the groundfloor only? Then to calculate W/m2 (for UFH), I take the Total Heat Loss value and divide by the heated floor area, which includes ground and first floor? Many thanks

I toppled a 3t digger back in July and was lucky to come out with only a bruised ego. Door open, no seat belt on, working on my own... Fortunately the hire insurance covered for incompetence! As the cab needed replacing. These machines have the potential to be dangerous beasts even in experienced hands. Not that I'd consider myself experienced but I've learnt a lesson about their limitations.

I will be using second hand OSB from a local firm who put up and take down commercial site hoarding. Might be worth a look for something similar in your area. I got 11 sheets of 18mm, painted one side for £70 last time i went in

@MikeSharp01 that is a solid solution. No doubt the BI was happy. Top job! I think I will try my best with offcuts and tape...

Yep, got double sided and single sided. Only issue is once I've got an offcut around the 6 ducts, I will be able to 'see' down between, where the ducts don't tessellate.

Sure is That i can do easily! First ever BC inspection looming, want to be impressing and not a cause for concern.

@Russell griffiths is that just a liquid membrane though? The Icopal product is a two part sealant, mixed together and poured to 30mm thickness before hardening. I don't think I could satisfactorily paint a liquid membrane around the ducts.

I have top hats to seal the 110mm waste pipe penetrations through my radon membrane. Simple. But also have a bank of 6x 63mm ducts to seal around too. What is the correct method to seal these? The Icopal Easi pour radon seal looks like a very effective (and costly) method. Any other methods equally as acceptable?

My BCO has approved my drain plan with internal AAV's at the W/C's and a low level vent in the front garden, much like @JSHarris is describing. Soil Plan.pdf

True commitment from the guy who showed up straight from the airport. Image of flip flops, Hawaiian shirt, dropping his suitcases and getting stuck straight in!

Ah yes I do remember reading that in one of your posts @JSHarris Considering my building is of a heavier construction to yours (ICF) and a full two storey, I could assume twice the ground bearing of 20kN/m2 Me thinks a 40kN roller will be on hire next week...

@PeterW that extract comes from the Ground Investigation report, the Structural Engineer is following it to the letter. I'm inclined to think he is being overly cautious (again) rather than incorrect. His 50kN/m2 ground bearing figure has been remarked as surprisingly low

@vivienz I'd say that's about 40kN model

My cautious ground investigation stipulates a 10 tonne static roller be used for compaction... I've just been looking through the hire catalogue and 100kN of force is a LOT bigger than I was expecting. So much so that I don't think it would be possible to get such a machine down to the required level without a crane/large hiab. An 80kN model doesn't reduce the size much. Can I compromise further without jeopardising the integrity of my foundations? Many people who have been to site, including a surveyor commented that the ground is excellent. Large fragmented stone, no organic matter. A ground worker who came to quote said he thought I could build straight off of it. What size machines have others used to compact the type1 on their rafts?

Does anybody know who makes cills like this? Photo taken at NSBRC

If this goes back to Thursday, I would like a gander if that's okay please.
