Construction Channel Posted March 10, 2018 Author Posted March 10, 2018 Well this is the start of the shower shuttering. I need to Cut a wooden brace across where the strap is and put more supports in but the corners are level and it’s in the right place. As for the pressure...... it’s gone up? I had left the hose connected which I have now taken off. So either that valve was letting by or it’s magic. Either way it’s not leaking 1
Nickfromwales Posted March 10, 2018 Posted March 10, 2018 Cold water has acclimatised to the ambient temperature and expanded a bit that's all. . 1

PeterW Posted March 10, 2018 Posted March 10, 2018 Wait til you pour concrete over them and then watch the pressure rise ..!!!!

Technically they are for holding Teram down but they seem to be working well for this. Pardon my ignorance, but do they pierce green polyethylene layer (and if yes - is it a problem)?

They do pierce it but tend to fill the hole they create as the membrane stretches to allow it to pass through. Not a problem. With liquid screeds it would be frowned upon. 2

I will leave them at about 1.5 - 2 bar when I'm pouring, for the moment I have released all pressure and left the drain open, it's not meant to freeze any time soon but i wont be pouring for at least a week so no need to take the risk

Construction Channel Posted March 10, 2018 Author Posted March 10, 2018 i should add the spikes are only 150mm long, the mesh is 50mm up on the chairs so it should only sink into the top layer of 100mm insulation (140mm in total) 1

Which reminds me that somewhere in the garden I have a couple of experiments I started months ago, with some mortar plonked on some samples of PIR, to see how real the reaction with the foil really is. They've been sat outside, so have been repeatedly rained on and snowed on, which should be a pretty much worse case. I'll dig them out, see if I can get the mortar blobs off and takes some photos to see what the real-world damage to the foil faces is, and then post it on the relevant thread (when I can find it..............). 1
Construction Channel Posted April 4, 2018 Author Posted April 4, 2018 the videos are slowly catching up with real-time. here's a 10-minute video on how to fill a UFH system from the wrong end . I got there in the end but the filming slowed down after I lent it on the aco... 1
Onoff Posted April 6, 2018 Posted April 6, 2018 Looks great! I'm sold on screeding to "rails" after doing my bathroom with them. My lounge /diner is a long and thin room like that or will be when I knock it thru. That'll get the same treatment! Mine has a change in level that I'll do away with though. What mix was that? I've never used pumped concrete, it looks very "runny".

It was gen 3, supposedly they won't put anything less through the pump, as for runny the ticket says no water added on site...... but between you and the world there might have been a little bit just to make life easier, if it has weakened it at all im not worried, its plenty strong enough for what its doing and its full of reinforcement

I asked for a 75mm slump, pump grade. The concrete company said that the minimum they could make pump grade was 95mm so I agreed to that. When it was delivered it was very similar to what you had there, and I would guarantee that it was a minimum of 120mm, maybe greater. The problem is, when you have the pump on site and set up, plus the required workforce, what do you do??

Construction Channel Posted April 14, 2018 Author Posted April 14, 2018 sometimes I like to watch my old videos just to remind myself how far I have actually come ( I build other peoples houses a lot quicker than I build my own) God, I have aged...... (shhh onoff, I am fully aware of the weight) this video is called Channel update 12/7/2015 1
