Am constantly amazed at how many forums exist covering every topic under the sun and here I am as a new member of yet another.
Only came across this forum whilst trying to find out the answer to a question concerning to DPM or not.
Have enlisted the services of a local builder to do the slab base for a potting shed, nothing massive 10ft x 7ft, told him if he does a decent job will get more work namely a 6m x 4m slab for a workshop for starters.
He quoted me a price which seemed reasonable to me. He then came round for a chat, and a beer, to say he was knocking £25 off as PAV1
concrete is to be used and hence a DPM was not required. Now I am not doubting his knowledge, well maybe I am, but wonder if others agree with this approach or should I insist on a DPM anyway. The potting shed has its own floor set on pressure treated battens so I think damp will not be a great problem.
Comments will be gratefully received.
For the few quid a DPM would cost (3m x 2.2m - 6.6m² so less than a tenner!) I wouldn't be without it, and it worries me that a 'builder' thinks it's worth the risk.
PAV1 *is* a specialist mix for paving and floor slabs, but it does NOT impart damp proof powers. Moisture can, and does, still rise through the slab.
