Tom Posted January 19, 2018 Share Posted January 19, 2018 Still at very early (as in still haven't bought the site yet!) stages of our project so still mulling over various construction methods etc. We like the look of ICF but I'm concerned what finishes we can have on the inside. Dot and dab plasterboard seems pretty standard but are we limited to this? I'd really like some board marked concrete inside - I like the look and it would also add to the thermal mass. Has this been done with ICF before? Is pouring a 1-2" thick vertical slab on the inside feasible? I'm thinking fix rebar mesh to the interior then build the wooden form say an inch or two off of this. I'm guessing there would be issues with the concrete pour/voids etc. Any ideas? Thanks all Link to comment Share on other sites More sharing options...
Russell griffiths Posted January 19, 2018 Share Posted January 19, 2018 A friend of mine is building a very modern build with board finish concrete on the inside, he is basically making the shell a concrete box with insulation stuck on the outside, it’s all been designed and looks cracking. The only problem is he can’t find anybody to build it, the general builders just haven’t got a clue unless it’s traditional brick cavity, so he’s having to look at civil Engineering companies. I would look on YouTube at the builds in the states as they are far more up on these methods. Also look at an icf product that only has insulation on one side and plywood on the other, you could substitute the ply for boards to give you what you want, however you would need to increase the insulation on the outside to make up for the lack of it on the inside.

Dee J Posted January 19, 2018 Share Posted January 19, 2018 Sounds like precast panels applied as a cladding might work. A quick google suggests such things are available. Link to comment Share on other sites More sharing options...
Tom Posted January 20, 2018 Author Share Posted January 20, 2018 Thanks both. DeeJ - can't find any of what you mention, though I'm finding it hard to imagine how such panels could be safely fixed to the wall. Link to comment Share on other sites More sharing options...
Trw144 Posted January 20, 2018 Share Posted January 20, 2018 This is above my bed - we used large format concrete tiles. I would take a better picture but I m still in my bed! 1 Link to comment Share on other sites More sharing options...
Tom Posted January 20, 2018 Author Share Posted January 20, 2018 Best place to be at this hour. I'm working nights so I plan to be horizontal in approximately 1.5 hours. Can I ask what your wall structure is and how the tiles are fixed to it? Link to comment Share on other sites More sharing options...
Russell griffiths Posted January 20, 2018 Share Posted January 20, 2018 As far as other finishes are concerned you can have any finish you want ,the icf is just the structure just like timber frame you can fix plasterboard on battens, tile, timber boards,timber sheets, have a look at a website called Houzz thousands of ideas.

Its a timber frame construction, with tile board (wedi board) fixed to the battens, and then these concrete tiles fixed using tile adhesive.

Luckylad Posted January 20, 2018 Share Posted January 20, 2018 Hi sounds like an interesting project. How would services work with this type of wall construction? I’m guessing you’d have to decide quite early on with switch and socket location? would the internal partitions have the same finish? are you intending to paint it?

Tom Posted January 20, 2018 Author Share Posted January 20, 2018 Really liking those tiles TRW, definitely one for the mood board. Thanks for the link too. Luckylad - with regards services I was thinking metal clad boxes and surface-mounted trunking to fit with the industrial look. Likewise leaving it unpainted. Perhaps more scope with different cladding for the internal partitions rather than having to find a way around fitting to the ICF? Link to comment Share on other sites More sharing options...

divorcingjack Posted January 23, 2018 Share Posted January 23, 2018 (edited) Gorgeous - thanks for the links everyone. Although, I cant't help noticing the lack of pricing ... Must mean I can't afford them dare I ask @Trw144 for an idea on cost before I waste my time sending in a quote request?

Trw144 Posted January 23, 2018 Share Posted January 23, 2018 (edited) @divorcingjack Just checked some old emails - the plaster 3D wall finishes were about £800-1000 for a 6m x 2.4m wall. The concrete panels (1200 x 600mm) were £56 each. Another option might be one of the microcrete finishes that are applied like plaster - either skimmed, or I guess you could possibly do the same thing with the timbers mentioned in an earlier post to get a wood plank finish.

Compared to the pre formed 'decorative' boards people have linked to I don't see you saving money.....just being subject to a more risky hit and miss result. I would say if you skip icf and end up doing shuttered concrete, don't be deterred from board finish on its expensive reputation. Materials are cheap, just rough sawn timber (which will mostly be re-useable), nails and wax. It's labour intensive but totally unskilled.

Having witnessed every moment of the process on mine i'd say he absolutely wants a specialist reinforced concrete contractor...there's plenty of them.....i'd certainly recommend mine if he's in range (dorset or bordering).

Tom Posted January 24, 2018 Author Share Posted January 24, 2018 How does shuttered concrete (+ external insulation) compare to ICF in terms of build cost and U values etc? I really like the rough and ready finish and would save on interior decorating costs.... Link to comment Share on other sites More sharing options...
mvincentd Posted January 24, 2018 Share Posted January 24, 2018 I'd think a simplistic comparison would show icf as cheaper, but an 'all things considered' project specific comparison might provide a different answer. Link to comment Share on other sites More sharing options...
bissoejosh Posted January 29, 2018 Share Posted January 29, 2018 We're hoping to have some concrete effect finishes inside, in particular on a 3/4 height wall separating our kitchen / dining from our lounge. I've seen the wall panels/tiles mentioned above but recently I've spotted another potential option which others might be interested in. The picture below is of a portable building (made in Spain by Abaton, and v.nice in my opinion) but it was the external finish which grabbed my attention - according to the documentation it is 'grey cement wood board' Looks like pre cast concrete from a distance at least and might be a lightweight option for wall decoration etc. I've not really seen anything similar in the UK but perhaps others have... 1 Link to comment Share on other sites More sharing options...
jack Posted January 29, 2018 Share Posted January 29, 2018 I'd consider buying a piece of cement board and experimenting with distressing it, including spraying/splashing parts of it with water, tinted washes, chemicals (particularly acids), or whatever. Try sealing the result with matt/gloss lacquers to see how that changes things. We had a couple of big offcuts lying around outside for several months and they developed an interesting patina!

I think this is just what we'd call "cement board", which is wood fibres in a cementitious binder. The stuff we left outside developed a similar patina over several months.

Juj Posted April 3, 2018 Share Posted April 3, 2018 This is an interesting idea, does anyone have experience with cemboard and do you think it could work as an interior wall finish? Link to comment Share on other sites More sharing options...
Alexphd1 Posted April 5, 2018 Share Posted April 5, 2018 (edited) A bit late but you get single sided icf with eps on one side and ply shuttering other side. Could be ideal for basements. Edited April 5, 2018 by Alexphd1 Link to comment Share on other sites More sharing options...
