I've had some bug for the past week and haven't felt like doing much. We did have a lot of rain recently and the paving outside has not only been raised to just under the last weatherboard (about 30mm below floor level) but does not slope away from the house. (I really don't get how concreters can stay in business for years when they don't know what they are doing!) We are just going to have to rip it all up and do it ourselves. Thank goodness we hadn't tiled the wardrobe and so can see the problem. The garage wall is going to end up with the same problem eventually as there doesn't seem to be any freeboard between the neighbour's land level and our floor level. How these things get past the building surveyor I don't know. Sigh! Another letter to the building surveyor on the horizon and some evasive reply no doubt. Re: Damp proof course 13Aug 28, 2013 9:42 am Actually just found some interesting articles on "damp" on the Archicentre website (which seems to have been massively overhauled since I was on there last): http://www.archicentre.com.au/publications Scroll to the bottom to "Information sheets inside your home" and there are articles on "Falling Damp", "Horizontal Damp" and "Rising Damp" - every damp you could wish for! Re: Damp proof course 14Aug 28, 2013 12:10 pm JazzyJess We use to get a pool between our house and the slope despite the builder having said we didn't need anything there. Frustrating experiences about the most basic of requirements like this just should not happen. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Damp proof course 15Aug 28, 2013 4:19 pm Just to clarify some points in case there is a confusion or misinterpretation of 'damp proof course'. With a slab on ground construction there is no 'damp proof course' as such. There is a plastic membrane under the slab to prevent moisture rising. In a brick veneer type construction on a slab there is a 'cavity flashing' which has the 'major' purpose of re-directing moisture that may penetrate the brick wall & then seep down the inner face, back out via weepholes. The flashing extends, horizontally, between courses which also limits moisture drawn up through the wall from ground level. In a brick veneer construction on a strip footing (floor on stumps) there is a 'damp course' in the brick work to limit moisture drawn up. Moisture penetrating the outer face, running down the cavity, ends up seeping to the subfloor area without reaching the frame of the building. Hope that clarifies.

Re: Damp proof course 16Aug 28, 2013 8:31 pm Thanks Ausdesign - I think I understand that. So with a weatherboard house on a slab we have the plastic membrane under the slab which I presume is the black plastic you can see in the photo
Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ and, as the paving at the back is now virtually level with the floor, we are getting moisture ingress horizontally under the weatherboards and through the base of the frame. Re: Damp proof course 18Sep 23, 2013 11:19 pm Hi Liliana, have a look at this document: http://www.concrete.net.au/publications ... mpness.pdf Page 5 has the detail for timber framed house. Unfortunately I think you are going to have problems from what you have described. As a side point, I'd always install a flashing or DPC under an external frame. Granted I don't generally do house framing so not sure if it is mandatory but anytime I have, I've always rolled out a flashing under the frame. Just gives me some piece of mind. Not that it would prevent the moisture you seem to be having.
