The slab was set out 6 weeks ago, and the plastic sheeting for the vapour barrier has deteriorated completely. One section which was older plastic is fine, so it pretty clear the product is faulty.
Question is... what to do about it. 240 sqm slab, waffle pod, reo all laid out and 1000m+ of in floor heating pipes tied down to the reo.
Going to have a look through the standards tomorrow, what alternatives are their to the plastic vapour membrane?
