What spec do you recommend for a new Lime floor and what membranes if any would you use.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=290&Focus=3277#Comment_3277 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=290&Focus=3277#Comment_3277 Thu, 17 May 2007 12:12:08 +0100 steve mac I have removed what I suspect is vermiculite granual insulation which had been laid between the joist in my loft. I would like to recycle it by way of mixing it into a concrete floor (2.5 m X 2.5 m )which I plan to do in the near future.
Do you consider this appropriate and if so what ratio of vemiculite do I use in the mix. My intention is a mix of 5 gravel to 1 sand. Your comments would be appreciated.

The top surface is dressed off with a derby and then swept with a stiff brush after 36 hours (using old celotex battens as 'stepping stones' to spread the sweeper's weight), then the floor is left to cure for at least 10 days under a polytarp before it's walked on normally.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=290&Focus=3368#Comment_3368 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=290&Focus=3368#Comment_3368 Mon, 21 May 2007 19:20:34 +0100 david Thorpe There is a company called Isokern (part of the Lefarge group) who manufacture high quality chimney liners and part of the system is the use of a leca cement insulation mix between the liners and the brickwork. Isokern stockists will keep bags of leca. www.isokern.co.uk.
