Our Structural Engineer has specified a reinforced concrete basement and suggested we use either traditional timber shuttering or ICF. I've priced up the ICF route but am struggling to find comparative costs for traditional timber shuttering, has anyone got any suggestions on which approach would be cheaper and by how much?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221191#Comment_221191 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221191#Comment_221191 Wed, 11 Mar 2015 19:24:46 +0000 Greenfish https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221194#Comment_221194 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221194#Comment_221194 Wed, 11 Mar 2015 20:00:12 +0000 willie.macleod https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221198#Comment_221198 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221198#Comment_221198 Wed, 11 Mar 2015 20:37:46 +0000 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221480#Comment_221480 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221480#Comment_221480 Wed, 18 Mar 2015 19:02:16 +0000 Triassic
Having read a number of basement web sited there is mention waterproof concrete, but then go on to suggest the use of waterproof concrete has to be closely supervised. I would have thought I simply specify the addition of a waterproofing addmix when ordering the concrete, or am I missing something?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221497#Comment_221497 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221497#Comment_221497 Wed, 18 Mar 2015 22:38:48 +0000 ringi
It is hard to stop water being added to the concrete to make it easier to lay, buy any added water will make it week and not waterproof.

Any joint in concrete must be 100% clean, or the concrete will not bind well enough to be waterproof.

All the above have to be done on a building site in all weather with workers that are not very dependable.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221506#Comment_221506 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221506#Comment_221506 Thu, 19 Mar 2015 08:22:12 +0000 Nick Parsons

....So don't rely on it being waterproof. Give that 'task' to another layer. Too much risk, in my view. You're only doing this once!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221535#Comment_221535 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221535#Comment_221535 Thu, 19 Mar 2015 11:43:51 +0000 PaulJ https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221542#Comment_221542 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221542#Comment_221542 Thu, 19 Mar 2015 18:34:23 +0000 Triassic Posted By: PaulJThe extra cost for the admixtures, waterbars and onsite quality issues probably exceed doing a type C internal drained cavity membrane with sump and pumps, which is recognised as having the lowest risk. Lucky my basement is open onto a lawn at the front, so water is not really an issue, just damp from the ground on the other three sides.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221546#Comment_221546 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13208&Focus=221546#Comment_221546 Thu, 19 Mar 2015 21:11:57 +0000 PaulJ
