Were you actually laying bricks under this or is this the covering when the rain came?

There is no mention of coverings in the contract but I'm willing to pay for/ allow use of materials on site to make a covering as it's ultimately for my benefit (and delays are costing me more). The completion date has passed but again, it's not really the builders fault as the rain fall has...

We've lost almost all of January to rain and February looks to be much of the same. Hence the final structural bit of our project (front porch) is continually being delayed (and holding up other work). Is it a done thing/ normal/ possible to use some sort of temporary canopy to allow...

Whilst I'm not sure if new builds are a good example to follow, what I'm saying is that in most of the rooms within the house there is clearly damp which has formed over the last few months. Simply dot and dab'ing new plasterboard over that doesn't seem like the proper way to do things. How does...

I should have said much of the house will have plasterboard with dot and dab. Is moisture behind the boards still not a concern?

Fair enough. When you say make your own with EX-foam, is it mostly a case of continuing the PIR to the end and filling the gaps? The D&D plasterboard on top? No concerns with bridging or moisture?

We have been carrying out an extensive renovation (with all the central heating having been removed). With the cold winter months, some surface damp has formed on walls. The central heating is not due to go back in for a 6-8 weeks+ The plasterer thinks it doesn’t cause an issue for plastering...

A bit confused by the different types of cavity closers available. I am now wondering if the inner wall is deliberately set slightly back to fit a single flange cavity closer?

I'm not sure I understand? My concern is that the damp may travel from the single brick wall through to the aerated blocks.

Unfortunately I'm still in the process of unpicking the nightmares the previous builder (who I had to let go), left behind. :mad: Looking back at photos and footage, I've noticed that there is no vertical DPC between the single skin outside garage wall (brick) and the internal block wall (shown...

I understand that would stop damp transfer but what about cold bridging?

I will be fixing it in place with general grab adhesive and clout nails on the inner walls. Perhaps I'm needlessly concerned about making it completely level at this stage?

So add now before the closer is fitted rather than after? Or can it be done either way? Also, what's an acceptable tolerance to not need doing this? As I may end up with the closer protruding more on the inner wall if I do this and it's not required. If you get what I mean?

We have a bit of a mix of new window/ door openings and one external doorway where the new wall joins an old wall. The the new build in some areas has a variation of 10-15mm between the brick and blockwork so the cavity closer would not sit completely flush. I'm not sure what the normal...

Or have I misunderstood what needs to be done? Based on ^woody^ posting this quite some time a go.

We are renewing our existing porch by making is slightly bigger and building it from brick rather than half brick/ half double glazing. The architect has specified a saw cut which I understand would remove a section of the existing wall for a continuous cavity? The inner and outer wall of...

Yes, but doesn't that cause at least SOME amount of rocking of the PIR?

Did you apply anything to the brick wall? We're being instructed to apply a scratch coat render before studding but I'm wondering if I should tank the walls instead? More so for the external facing wall.

So would you suggest putting sand down in any areas lower than 2-3mm but leaving the rest as they are? Perhaps laying the PIR in a way that it doesn't over hang beams so there is always support at the ends?

Having spoken to 3 different screed companies, the current product of choice seems to be Cemfloor - a concrete based screed which I was advised to go for 50mm. This would take us up to DPC with a 90mm PIR. There are no door frames in place and the ground floor is literally an empty shell at the...
