Hi, I’m here because I’m unsure if my builder is making a mess of things. My instinct says yes while everyone else is saying it will be fine. It is just his word against mine atm and I really can’t afford to fix this in a few years time if all goes wrong so wanted to ask for advise here. The builder was under pressure to have floor prepped for my plumber to install underfloor heating pipes the following day. It’s an open plan space of 65m2 and he had to get the sand blinding down, whacked and made level and dpm and insulation boards down. He had 5 lads on it and it was during a torrential downpour, they were obviously in a hurry to go and did all of this in 3 hours max. I’ve now discovered rips and perforations in the DPM that defeats the object surely? DPC that is not lifted over the DPM and DPM not brought above planned screed height. There are large gaps where insulation has not been cut trim to the wall and the whole site is swimming in water. Insulation boards also rocking from uneven sub base which I’ve been told the weight of concrete will fix. Also, is it important to tape the seams on the DPM and insulation boards? And does there need to be a sheet of DPM on top of insulation as well as below as I’ve heard concrete can damage insulation over time? The last photo is showing a ventilation pipe. It is suspended off the sand blinding by an inch in places and has 15mm strips of insulation capping it. Any insight appreciated. Cheers
Isn’t the building inspector supposed to see this before the screed goes down? Sent from my iPhone using Tapatalk
I'm not aware merit. It's all been a little vague with the COVID situ. I'll book him in before any concrete gets poured
