    However ASMET or roofkrete don't seem to need the PVC and other materials to make them waterproof. Also, because the roll sizes are limited how do you ensure structural and material integrity at the joints?

    Don't they? It isn't really clear how ASMET is made waterproof as we do not have enough information about the material composition from the ASMET boys. They use words like minerals to describe what is used but don't say what else. I suspect there is a polymer in there somewhere, something like SBR perhaps?

    Interesting stuff, and as they say like Modroc, which I've used for model making in primary school. I notice that BD prices it at £15 m2 not sure how much it would cost for the little bit I would need ( 28m2). It's so mouldable seems a shame to use it for a flat roof. I wonder if you let a layer set you can join subsequent layers without needing a bonding agent?

    I loved the the example of the buildings in the article - cement inpregnated fabric inflated on site and hosed with water to form a shell.

    I'm a newcomer to this forum and during my browsing I came across this rather interesting discussion. One thing confuses me though, and it seems I'm the only one to notice the following, "No secret formula just ferrocement" which has been posted by steveleigh at regular intervals throughout the thread.

    Can anyone tell me what exactly he is referring to? I assume it isn't ASMET?

    ASMET/Roofkrete is (or was) just ferrocement, of a particularly refined kind.
  7.  
    Oh, so does that mean that ASMET is now defunct? It sounded from the previous comments as if it might become the next big thing. Steveleigh seemed to suddenly change from avid ASMET disciple into cynic!

    Do you know where I could find more info on ASMET? I'm researching sustainable construction methods on behalf of a university.

    Start at the beginning of this thread - it's all there! I'm not sure of current availability - big ructions in the co. recently. http://www.roofkrete.co.uk (the old co, possibly still going, from the Newton Abbott address) and http://www.krete.co.uk/ (the would-be new co)

    ooooh intrigue...

    It does seem intriguing! ASMET, shrouded in secrecy.
    Will try to contact the Krete company and find out more. Has anyone heard anything from them recently?

    :clap::cheer:

    Looks like Roofkrete still struggling to shake the slightly dodgy rep...! I particularly like the bit where Mrs Krete asks... "does any architect know of other membranes which are approved by the green building forum..."

    get that: "approved by the green building forum" !

    I really am quite keen to use it... ...but do wish Icopal or someone would buy them out and stop the whole thing looking so Rogue Traders... (note 'looking')

    thanks for that info. it seems that this company has a decent product but less decent marketing skill...

    but I think that if ASMET/ Roofkrete really does everything it claims, and someone could market it properly, then it could do quite well.

    :confused:

    Too much secrecy for me.
  15.  
    Mike, was the company being secretive about particular areas? or just overall? I just checked out the website, there's a lot of info there, perfect for research, but I'd like to make sure it's legit first. Do you know anyone reputable who could discuss further with me?
  16.  
    I know nothing of the new company. My only contact was Steve Leigh who was [is?] an installer. He always maintained that he could not reveal the material composition, which Is what I was interested in at the time. Have you managed to find out what it is made from?

    Mike, have you seen the above? it seems to be scattered throughout the whole thread. I don't understand why Steve Leigh would suddenly change his position like this, when he seemed to be so passionate in the first place. There seems to be something a bit strange here. I have no idea what the secret formula is, but it has been previously mentioned that it is patented?
    I would also like to find out, as I know of some folks in Brussels who are quite interested in this.
    Also, have you, or anyone else on this thread, got any video evidence of the ASMET house in action?

    It's no secret - it's all in this very thread - what more does anyone want?
  19.  
    Seems like Steve may have edited his previous posts somewhat. I will have to read the thread again

    If it helps I've had very helpful communication directly with roy jenkins the md.
    I've specified 'roofkrete' on a current project so should have installation feedback and photos later this year.
    34m2 flat roof terrace plus parapet upstands as per the top detail on parapet pdf here:
    http://www.krete.co.uk/technical-information
    His number is listed on the website so dont see it a problem to post it here

    Has anyone else use roofkrete? I'll be neededin to make a flat roof later this year so I'd better consider the options. I guess this one. Perhaps relatively untested?

    Take a look at the website wookey, it's well tested and proven.
    Give him a call and ask for details of the most local approved installer, they will probably be approved for a number of systems and can advise you from there.
    No point choosing a system then finding no-one can get to you cos they're miles away.

    Any idea of cost...?

    £70/m2 rings a bell but that was before the latest "restructuring"

    Quote from an email from someone ( apparently no longer with the company) at Roofkrete/Krete last July. "The rate of £75m2 is about right - it can vary (either way) dependant upon complexity, size and location of the individual project."
