Browse Forums Building A New House 1 Aug 25, 2010 3:06 pm Just wondering if any forum users could provide advice in relation to Damp Proof Course installation. In the photograph provided below, should there be evidence of a DPC along the slab edge continuing down to beneath the brick sill? Is a DPC required to be installed at sills to doorways such as in this photo? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I have read also that a DPC should be visible through the side of the brickwork in accordance with BCA requirements .... this doesn't appear to be the case with our brickwork. Is there a possibility that a DPC membrane may be installed but has only been carried across half the brick width. If this has been the case, can anyone advise if this is acceptable practice to meet the BCA requirements. Looking forward to receiving any advice.

Checked our construction photos, all our external doors (timber framed) had a DPC applied under the brick line where you have shown. As far as being able to see the DPC, this is something the building surveyor should look for. I remember at our Lock-Up stage I asked our SS to trim the DPC as it was sticking out a fair way in places. He refused until the surveyor came and inspected as he said the house would fail inspection if it was not visible. It is highly likely its there but the mortar has covered it. If the surveyor has a problem with it not being visible it will fail inspection and therefore they wont provide the certificate of occupancy at the end of the build, so the builder will need to take action. The surveyor comes at pre-slab, slab steel, frame and final so they wont be back till the end now and really you do not want a major complication like this close to move in day! If your concerned, discuss it with your SS and have your own independent inspector through at lockup stage (as has been suggested). Re: Opinions Please - Damp Proof Course 4Aug 25, 2010 10:32 pm I don't think it's done at sills to doorways such as in your photo. However, the doors should sit on a piece of "damp proof" material, especially if the bottom of the doors is timber. To check for the DPC in the adjoining walls - do you have a pic that shows a sideways (angle) view - I just checked ours and tehre is a normal DPC flashing visible on one side. Can't find the rest of the pics ... Or, can you look at the weep holes really close up - there should be a piece of flashing visible at some point (might need to clean them up a bit and take pics with good camera and inspect the pics (it's amazing what a magnifier can find ). I don't know if inspectors have some smart tools to check for existence of DPCs, but if everything else fails and you really need to know the truth, there is always the removal of a small section of plaster.
