Hi, I’ve just laid the first width of tanking membrane, and annoyingly there are a few air bubbles in the middle of the sheet. The biggest is probably 3cmx2cm and a few mm high. is there a way to resolve this? Is the butyl rubber back ‘liquid’ enough to seal its self if I put a pin prick in to...

Thanks - I will fix the tray to the boards. As for the waste - it won’t be accessible after its all tanked; but thats nothing to do with the boards underneath. I am using this...

Hi, I am installing a grp shower tray former on timber joists and I am struggling to get them perfectly level. is there anything wrong with laying 18mm boards on top of the joists and then the former on top of that. I’ve dry fitted out and it feels much more secure, but I’m not sure if I’m...

hi, I am part way through a loft conversion and will need to start the wiring for the electrics fairly soon. It will have a bedroom bathroom and landing. I will be running a new circuit for the lighting, and a new one for the sockets. I just want to get the wiring in before the floors go down...

Hi, I am converting my loft and i have a question regarding how best to fix the new floor joists. We are lucky with the construction of the house; the new floor joists can run from the current inner wall plate under the eaves to the central spine wall. My question is how best to fix them...

Thanks for that, I didn't know those machines even existed! Regarding the floor, everything I've read mentions bonding it down, what's the reason not to? Thanks for your help James

Hello, I am half way through an extension and am think about flooring. I would like to lay an engineered oak flooring in the extension, half of which is new, and half existing. The existing half has vinyl (i think) tiles which i was planning to pull up, and then self level the whole lot and then...

Hi, I have one proper slab - 150mm w. steel mesh, then some sand blinding, then the DPM, then 100mm of celotex. I then should have poured the remaining 130mm upto FFL, but i didn't - don't ask me why! I am now 50mm short of FFL. I suppose all i would like to know, is not whether a screed is...

Hmm just googled that stuff, 40 bags @£18 a bag.... Not sure that's a goer! I guess my question is, will a concrete mix work, even if it is not the preferred method? I've also read something about grano mix, does any one have any experience with that? Thanks James

Hi, I am building an extension and where the new floor meets the old there is a 50mm height difference. The new floor is Hardcore -->concrete slab-->100mm celotex-->75mm concrete subfloor. i know i should have poured the subfloor to within a few mm and then used self levelling compound, but i...

Thanks for the responses - i will get a Gas Safe guy to do the whole lot.

Hello, I am after a bit of advice about some gas work i need to have done and would like to know of what i am planning is ok. Part of a kitchen extension involves moving the cooker from one side of the house (which currently has the gas pipe running alongside the outside wall) to the other side...

Thanks for the replies. I actually went and bought a bigger one today - we still haven't decided exactly what size doors we need so it made sense to put a bigger one in just in case!

I have an 1800mm lintel, and would like to create a 1520mm opening. It will be supporting one course of bricks and then the eaves wall plate and roof structure of a 3.6m lean to roof. I know that the minimum bearing is meant to be 150mm at either end, but given that i will be only 10mm...

I have just payed £135/m for some mix on site c35 concrete in Hampshire. had i needed more than 1.5m i am sure it would have been a better price. For comparison it was going to be £125/m for standard c20.

Because when I asked for help I hadn't started. I now have
