if you are able to zoom in, on the first image you can see some wedge shims on the furthest away rafters

The roof is quite large, the rafter ties have been cut, gussets fitted, it spans over 7.4m, heavy roof - CUPA H3's, where the rafter doesn't quite sit on the beam is represented on the drawing. I'm thinking, hardwood shims (replace current C16 shims), or if I have to, glue/screw uprights to the...

hey all! Got a problem. Retro fitted a GLULAM ridge beam and glued/screwed 4x2 onto the edge of the current 5x2 rafters. Fitted mini collars above where the GLULAM beam was being sited, using tech screws, not nuts & bolts (used a laser level to keep them the correct height, leaving the 115mm gap...

I had thought of sand but wasn't sure if 10mm is too much of a deviation, it's not like concrete tamping ridges, it's more like small slopes in the slabs. When we poured it, we couldn't screed it because of risk of damaging dpm on top of the dwarf walls so all the slabs were tamped. I mean it's...

I have thought about that. I'm guessing sharp sand because it kind of locks together better?

correct. Once the PIR is installed, I'm laying vapour barrier (visqueen), under floor heating, then approx 65mm screed. The same method I used on the self build of my other house back in 2010. I have set a datum using my Huepar 360 and a long brickies level, where I drew a line. That's how I...

C30 is 100mm thick. Under the DPM is compacted (every 100mm) type 1. When I mentioned self levelling, I meant on top of the slab to level it, before (re)laying the insulation (100mm PIR). Now, I'm going to level the slab with compound, leaving the dpm in situ on top of the dwarf walls. When set...

Looking for some advice. I am preparing to install insulation. Actually, I installed it but I am not happy with how it sits so it's coming back up. Floor area is about 90m2. The attached sketch shows the make up of the subfloor. There is (insulation) movement all over the floor, about 10mm...

apologies for bringing an old(ish) thread back to life, but does this look okay or...? I've emailed this sketch to my BCO for his input. The house has a new cathedral ceiling and originally, the roof had lightweight cement tiles. I want to install CUPA H3 Slates which work out around 49kg per...

No, I live in a recently built (2010) house approximately 50 metres away from this one. The house being renovated is my old family home

decided to go with short collars screwed to the rafters, gap the same as the thickness of the GLULAM (115) then pushed the beam up to meet both collars and rafters at the same time. Only hope the BCO is happy with it, inspection next week. Why do SE's make things so awkward, like, wanting me to...

Update! Gable and mid-house load bearing partitions built, gable panel bolted by 10 x 150 concrete bolts top and bottom of each panel stud, 45 x 45 strapping fitted to block wall with 50mm PIR in between block wall and load bearing wall. Rafters have been extended (deeper) with 45x95 C24, glue...

The SE spec'd 15mm Ply Gussets fixed by 14 nails per member. I'll be using 18mm OSB3 fixed with expanding PU and about 14 nail fixings per member. I'm hoping when he says Ply - OSB3 would do the same job. The rafters have the extenders fitted now, the beam *is* going up and just touching the...

I was gearing up for birds mouth cuts with the trusty self levelling laser this morning then I spoke to my SE. After I told him I could either plumb cut with heavy duty L brackets into the beam or birds mouth the rafter extender pieces to the GLULAM (115x495x6355), I asked him what is...

I did see them, priced them up, £500 + Veg and Tatties for 26 of them. They want the angle of the bracket slope, not roof pitch. Thought they'd be able to work that out if I gave them the pitch. I can get one to fit, 105mm tall (SAE-250X). Now I want to birdsmouth the 45x95, am I right in...
