stewie 3,387 Posted October 16, 2012 Report Share Posted October 16, 2012 Gaz price up using 6" block It's hard keeping water out of 4" block even when it's rendered , so am told by a building friend How come houses are waterproof then Chid? A good scratch coat and top coat of render with added waterproofer and then painted with exterior masonry paint will keep the water out.. because theres an outer skin of bricks and a layer of insulation............ That helps, but if a job's done properly, the only water in a cavity should be condensation from the inside and it should exit at the bottom via the weep vents. If the outside wall isn't waterproof, the water will bridge across the wall ties and cause damp on the interior walls. The insulation is there to stop heat loss, it isn't there for protection against water ingress.. Stick to the scrap and leave the smart arsed comments to those of us who have actually worked in the building trade... true mate but if its a single skin of blocks where will the cavity be.......... nice edit malt............

jessdale 416 Posted October 16, 2012 Report Share Posted October 16, 2012 For the terriers mine is 2m x 2m. One day for the blocks, half day for the roof and kennel fronts ,half day for the quarry tiles and a day to paint it. 1 Quote Link to post Share on other sites
MATTI 34 Posted October 16, 2012 Report Share Posted October 16, 2012 The block work will be water proof, but the galv roof sheets will condensate unless lined with ply-wood, also they are red hot in summer & freezing in winter unlined. I would opt for a felt roof, good luck with your project, mate. Quote Link to post Share on other sites

Chid 6,615 Posted October 16, 2012 Report Share Posted October 16, 2012 , but the galv roof sheets will condensate unless lined with ply-wood, not if you get the roofing sheets with the fuzzy backs (dont know the technicle term ) its like a felt back and it stops condensation and its only about 50p - £1 a meter extra Quote Link to post Share on other sites

Gaz_1989 9,539 Posted October 16, 2012 Author Report Share Posted October 16, 2012 Thanks folks. They are the roofing sheets i was going to use. Jessdale - nice setup. Similar to what i want the end product to be like but with galv panels to divide the runs up and without the quarry tiles. Although i do like them! Cheers Gaz Quote Link to post Share on other sites
christian71 3,187 Posted October 16, 2012 Report Share Posted October 16, 2012 4" block work pointed right then painted will be fine no need to render. And there are loads of single skin garage's. 3 Quote Link to post Share on other sites
Qbgrey 4,170 Posted October 16, 2012 Report Share Posted October 16, 2012 4" block work pointed right then painted will be fine no need to render. And there are loads of single skin garage's. yup,you be better using medium density blocks,fenlights,or even better the concrete ones,fully pointed both sides,you could tyvec the back then batten out and weather board but decent paint should do it.long or highish walls are a bit wobbly in single skin 100s until you get the roof on.
