Hi @Mudscience The fibres were from Adfil -- but you can't buy small quantities. I was very lucky that they were kind and gave me a sample (my patio wasn't tiny - 100 sqm). I can't remember which specific type. I think the fibres you typically get for DIY are not really effective (from the...

Hi @Unclesam12399 - not sure you could lay direct on block and beam (I am completely untrained btw) -- I think the challenge would be setting up the beams - they are designed to be square to each other I think. If you allow enough space for screeding (which our builder didn't do) then that's...

It's been a while, but here is the plan we used. The fibres we used were from Adfil

It worked - with the above plan and some special fibres for ultra thin screed... beautiful

Sorry, I thought I had posted about this. Yes, SORTED! and very happy with the result. Together with my husband laid 90 sq m of large limestone slabs on Wallbarn pedestals ranging in height from 5mm to 44mm. We laid drainage slopes first with concrete, using some fibres for strength in the thin...

Thanks - we've gone ahead now and laid them without a mat; maybe a mistake, haven't grouted yet (room doors delayed by six months so can't finish tiling). Decided it is the entire raft that vibrates so probably ok (ie floor is floating concrete slab and moves, but it presumably moves all in one...

Here's my shuttering plan -- the square kitchen patio already has a 1 in 100 slab laid, it's just the curvy bit we need to build. All slopes will be such that the raft thickness ranges from 55mm to about 30mm. Can anyone suggest ways to minimise risk? And should I prime the block and beam...

I'll get some pictures up tomorrow. I am only reckoning on 4 planes in total - it isn't that insanely complex! Will think some more. I have yet another landscaper coming tomorrow. They usually spend hours pondering and then say they can't fix it...

@kingandy2nd -- you're right - the slabs are from 50 x 80 to 50 x 40, beautifully milled limestone so very smooth I have considered what you say; but we need to create a slope of at least 1 in 100. So we'd still need a thin screed to lay the slabs on. If we just mortar on the block and beam...

Hi -- thanks - yep, figured out the rebar won't work. Half way through the project so it's hard to change - slabs already bought (8K). Decking difficult to build in this context and I don't like it either. The builder (long gone) made a lot of mistakes - the block and beam is simply too high...

Hi I'm looking for advice on the recipe to use for concrete. I'm about to lay the concrete slab on which I'll fix my 30mm thick, large, rectified stone slabs using pedestals. The pedestals are needed to overcome multiple problems of levels and drainage. It will be laid on top of block and...

Hi - Huge thanks again. I never want to interact with a builder or an insurer ever again... The insurer gutted most of our house then after a year said they couldn't find a builder (!) to do the repair work. So we got a single quote from a random local builder simply to show it was...

You're quite right about using default codes. Can you please advise where I start to find out how to set the system up myself? I find the pyronix manuals either obvious or not detailed enough. I've scanned a lot of good advice on this forum but never immersed myself in it. Will have to now. I...

THANKS -- 1111 worked. Hurray for you guys, and DIYnot which has got me out of a lot of messes over the years :-)

Thanks Secure I AM -- agree about the risk of insurance cover being refused - I don't tell the insurance company I have an alarm. Chances are the one time you're burgled will be the time it isn't set, and I believe if they can, they will find reasons not to pay up.

@sparkmarka - I'll try to fix it myself first, but before I saw these replies above had decided I need to find a proper installer who can tell me how it works as well as stop this issue.

will try 1111 then follow SecureIAm's suggestion. The installer told us that Napit was what we needed for the installation to meet insurer's requirements. Not surprised it means nothing, typical of the builder and his subcontractors. Wasn't impressed by the installer, who couldn't answer my...

Hi - it's 2222 Pyronix have told me the default setting is that after a tamper you need an engineer restore! They say it need to be changed when installed. I can't imagine who would want to require an engineer visit to restore after a tamper - how do you replace batteries? What a strange...

Hi Pyronix alarm system one year old. I removed the cover of a sensor to paint round it. Switched the tamper alarm off. Finished painting, replaced cover, tried to reset the system -- now the system is saying 'engineer restore required'. Control flashes continuous orange. Has been like that...

Hi, Is it ok to protect a DPC by chasing in lead one course above it and laying patio up to it? Any hints on how to do it? Landscaper has built a 120mm reinforced concrete raft for a patio to replace part of an existing patio (it's 3 ft above garden level but same level as kitchen). The raft...
