    Installing Laminate Flooring - Damp Proof Membrance 6th Jan 18 at 7:43 PM
    Hi,

    Wondering whether someone can help. Going to install some laminate on a concrete floor and have ordered underlay with a vapour barrier. However I have read in some places that I still need a damp proof membrane. Is this true?

    Thanks

    You probably bought an acceptable underlay and wont need a separate barrier.

    Have a look at the various types in

    http://www.vitrex.co.uk/products.php?subcat=39&name=Underlay

    See if one of these is yours. Personally I prefer their Premier Board and a sheet of polythene membrane, as the board is easy to put down and has a good thickness, to help if you have uneven surface. Plus it has some sound/insulation benefits, better than lots of others.

    If you check Screwfix
    https://www.screwfix.com/c/building-joinery/underlay/cat850024#category=cat850024&page_size=20&page_sta rt=20,

    they have several, too.

    However on another site I read that even though an underlay has a vapour barrier, you still need the membrane. This is all news to be as in the last house, I didn't consider a damp proof membrance.

    I have installed DPM and they are not too expensive but you also need to get moisture proof joining tape if joints are needed.

    There is specific underlay sold top put under laminate that is laid on concrete floors.

    You can buy it online which is much cheaper even with delivery than the price you pay in the shops.

    There are many online shops for flooring. But as per my experience "Inovar Floor" is the best online shop for laminate flooring
