D Walter Posted December 20, 2018 Share Posted December 20, 2018 I have seen the delay argument before in relation to internal insulation but I am a bit sceptical and so am making.sure there will be no air gaps between finished plaster and Velox. Probably not a big issue but would be interesting to see it modelled. It would be worth checking how the Izodom system is specified for a build as it does look complex and may need computer modelling. Also worth checking how quickly you can get components to site. Changing features of your build may be difficult/cause delay if it is dependent on specific modules. If it all fits together like a jigsaw puzzle changes.could be problematic....

scottishjohn Posted December 20, 2018 Share Posted December 20, 2018 I don,t think its any more complex than other systems --just many choices of components --seems to be 3 different wall systems depending on what you want to do and insulation level i will be getting a quote from them and velox once i get my design sorted out ,when planning have agreed to changes --both systems have good points Link to comment Share on other sites More sharing options...

I just think the chased electrics will be a real pain and not as simple as they say ,then finding old style plasters that can do a real two coat system, just sticking drywall on the velox is not the same as REAL two coat plaster finish ,will still be air gaps.

jack Posted January 17, 2019 Share Posted January 17, 2019 Looking good. If I ever build again, I'll definitely be looking at this system! Link to comment Share on other sites More sharing options...
Mr Punter Posted January 17, 2019 Share Posted January 17, 2019 This looks terrific @D Walter. Is this a self build or main contractor? All looks very professional. I like the blue bricks on the curved retaining wall. With the reinforced concrete walls and floors it will feel bomb proof! Did you look at doing a blog, as I had to switch between this topic and this one If you did this as a blog it keeps the thing together and the comments appear at the bottom of each blog entry. 2 Link to comment Share on other sites More sharing options...
D Walter Posted January 17, 2019 Share Posted January 17, 2019 Hi Mr Punter and thanks for the vote of confidence. I will put together a blog but have been mostly responding to questions on Velox/ICF so far. I do have a main contractor (a friend who is a carpenter by trade and his brother who is the brickie) and all trades and materials are run through their company. I do most of the research into the non-standard components such as ICF, metal roofing, metal and timber/composite cladding, MVHR, balustrading, windows, composite mesh decking etc..etc... and only get my hands dirty when emergency labour is required. I also do most of the liaison with architect (very little), structural engineers (lots but thankfully now finished) and steel fabricators (lots at the moment). My builders have been brilliant with real attention to detail and regularly come up with suggestions to improve the build quality and less frequently to save cost.

nickw Posted February 8, 2019 Share Posted February 8, 2019 Definitely looking good , I'm considering Velox but also durisol and isotex , atm Velox comes out higher in cost than the other 2 and its keeps swinging from one to the other on what i'm going to use.

A few of us the same i think my view on chasing walls for electrics has now swung in favour doing it +hard plaster finish I have been given rough quotes for spray plastering ,as they do on mostly in EU around £8per sq m ---so maybe could be the right way -- contractors -come in !"hit it" and its done I have not had a firm quote yet for fabric of building as still don,t have finished plans --but suprised velox is more expensive. or are you including using Velox type floor system as well ?,which could distort comparison some what if not including joists and flooring for other systems I was expecting it to be cheaper as much simpler wall panels ,maybe all the metal ties and things Is the the extra concrete thickness --150mm in stead of 120mm ?

scottishjohn Posted February 8, 2019 Share Posted February 8, 2019 I,m talking rubbish --as usual ,some would say just made my own enquires for contract plastering -hard verus drywall. the ICF supplier was being a salesman again i think quotes I have just got are arond £25 per sqm --and very little difference between drywall +hardwall in costs just more drying time for 2 coat hardwall system If anybody knows different please enlighten us Link to comment Share on other sites More sharing options...

Nope not using Velox for the floor system just a straight quote at present for outside walls. I'll be chasing out for all pipes and cables and i'm also looking at plaster instead of Drywall. Had a quote for outside render on the durisol...£40 sqm as they say it needs mesh and 2 coats grr not just a spray on 1 coat that parex says is possible , that adds 25% on rendering cost. the list of things with bills that get bigger is so so long ? 34 minutes ago, scottishjohn said: Link to comment Share on other sites More sharing options...

Wish all of mine was clad now all I am suprised at the need for mesh on a rough woodcrete block -- woodcrete will have as much if not more grip than brick or block work . maybe its the way i read your post i read it as though the mesh was needed because of type of block as an extra to normal rendering ?

Yep I was surprised too, was told the mesh will stop any cracking , the 2 coats of render is to flatten out the voids and any wall variance , but still I was suprised it can't be done with just a one coat spray render.

scottishjohn Posted February 8, 2019 Share Posted February 8, 2019 not impressed how they seem to make big deal of a 2 years no crack warranty -- like my pebble dash on my current house has been there 30 years and is fine --no mesh just sand and cement . so juts how much better are these fancy renders --makes you wonder Link to comment Share on other sites More sharing options...
scottishjohn Posted February 8, 2019 Share Posted February 8, 2019 (edited) after some more talking to plasters another suggestion came up --which could be quite good bury all electrics totally in wall then, as the woodcrete walls are flat anyway glue and screw drywall directly to walls -- not really dot +dab --but hard up to wall ,as you can screw directly to woodcrete + the plasterboard glue then apply simple but thinner 2 coat plaster finish . cost of doing base coat i have been told by 3 different people with be about same price as plasterboard,,but no chance of problems with wet plaster adhesion ,as some feel the woodcrete could suck all the life out of the first coat cos its very absorbant so could need some sort of sealing to be super sure of good adhesion and correct drying cycle . now it will cut cost down as I will be fitting all the plasterboard,except metal corners --most plasters like to do that them selves +just simple plastering job for the professional Edited February 8, 2019 by scottishjohn Link to comment Share on other sites More sharing options...

D Walter Posted February 8, 2019 Share Posted February 8, 2019 For inside we looked at 1) traditional plastering; 2) parex spray plastering; and 3) "glueing and screwing" plasterboard with skim coat, on our interior Velox walls. We are going with the "glueing and screwing" but to avoid any air gap behind the plasterboard I am going to cut off every wire tie on the inside walls as they are approx 5mm in depth.

nickw Posted February 13, 2019 Share Posted February 13, 2019 Still can't decide which system to use. Just fed up with all the "we're better, rebar/no rebar, no propping/shuttering needed, pir vs graphite, local support, and all the sales patter. What I'd like is guarantee in writing that they will send enough material , I wont have a blow out if layed correctly, they will hold my hand on the first and second pour, they will find me local tradesmen who have experience in the pumping, rendering and anything else that is specialised to the icf and not just give out some names that in reality when I speak to them they are either too expensive or not really convenient for my area. Like a holy grail that isn't to be found. I haven't got the luxury of using a contractor and so any mistakes in time or materials is going to cost me. 1 Link to comment Share on other sites More sharing options...

Which is exactly why, after 4 bursts in four pours, on the last pour I was quietly physically sick behind the site storage container. And, by 6.30 that night, pissed as a fart because the final pour went off without a hitch. My signature mentions avalanches - it should also refer to grim determination.

But i do know which ones I would trust having talked /grilled them all. where in the world is your site ? could be like me there will be no LOCAL tradesemen,depending what you call local ,that have done lots of ICF pours I doubt it is any worse for you to get a concrete pump than it is for me 100miles away £600 for 8hrs on site Link to comment Share on other sites More sharing options...
