I live in an old farmhouse in a rural area. I have an old stone and lime mortar built outbuilding/shed next to the house. It gets very wet in the winter. It is already electrified as my well pump lives there. I need to weatherproof it so can put a washing machine, freezer, etc. out there.

The water currently comes in in three main ways. First, one stone wall of the shed is up against an earth bank, so some water seeps through it. I was thinking of digging down with a spade to ground level through the earth bank and putting plastic tanking sheets between the outside of the wall and the earth bank. I could also use paint-on plastic tanking on the inside of the wall to be sure, to be sure...

Second, condensation condenses on the corrugated metal roof in winter and freezes. As it melts during the day, it literally "rains" inside the shed - big problem if I have electrical appliances in there. Is there some kind of spray on insulation I could spray onto the inside of the corrugated iron roof to stop this happening?

Third, there is no door on the shed. I will put one on. Obviously. But, it won't be completely waterproof, there'll still be a fair amount of "ventilation", but that should be ok if the shed is mostly dry? Presumably a bit of air movement is preferable or should I be looking to completely dryline and insulate the shed?

All advice is gratefully received - I'm not great with this kind of work, but I'd like to do it myself if I can.]]> https://www.boards.ie/discussion/2057281832/flat-roof-patio-waterproofing-systems Mon, 01 Sep 2014 20:40:55 +0000 Construction & Planning theoptimist 2057281832@/discussions I'm looking at both systems for a patio with living space underneath.

At the moment we have the concrete slab with concrete screed
The Botament rep recommended this concrete be sealed with their paint-on product, then insulation, screed with a fall, their sealant/adhesive with a membrane laid/stuck down to it (overlapping with adhesive used to seal joins), then tiling using the same adhesive and their grout.

The thoroseal appears to be just a paint on product, (cement based tanking slurry) however the guy in The Damp Store says they've been using it for 40 years with no problems. Maybe simpler is better?!

The botament seems to have more layers of protection however... their paint-on product sounds very like the thoroseal but is only the final layer of protection in case everything else fails.

How do I decide what to use?!]]>
