DPM/Visqueen

 What the hell has happened to this site? It used to have real people on it that could answer a question like this.Pilch

When do you need it by and how bulky is it.  My husband is driving down to Puglia at the latest beginning November, possibly few weeks before.  A break of journey in Abruzzo would probably be helpful as he will be on his own. 

I have someone that can bring it over by 15th Oct but, the way things have started to move, even that will be too late. Looks like I'll be using whatever they have at the local builders merchants & be very careful to avoid puncturing it. Needs must when the devil drives. Thanks all the same for the offer though.Pilch 

The black plastic on a roll will serve just as well as Visqueen - as long as its not punctured  [in fact any plastic will] . Visqueen is essentially just a thick plastic. To help stop it puncturing, lay it on a thin [2"-3" thick] of compacted sand and don't walk on it unless you really have to.    I'd also suggest that you use it double [or treble] thickness,For any joints - overlap by at least 12" and seal the top edge with any decent wide tape If you want a thicker plastic [it would be preferable] you could try to see if anywhere has the plastic used for large polytunnels - or if its a smallish area - perhaps a tarpaulin would do   [what are you concreting?] Hope this helps   [sorry - was in Italy, chilling out at the house, when you posted]  ["Chilling out " = no phone, no TV and no Internet  =  bliss]

You could add a waterproofing agent to the concrete
