You are right but if you raise DPC you can raise external ground levels and still comply with BCA and I suspect that is why it is done.

However if that is the case then why do we place the DPC one or two bricks in. surely its better to have it below the first row?

You got me thinking some more. I must admit when I built my house as an owner builder I didn't really think to much of this. However being me and waiting to improve things where I can I want to run something by you. On the blind side of the house I have 1 meter of concrete which is correctly below the weep holes. However I didnt just slope it away from the house as I didnt wont water and problems when it goes into by neighbors property. So instead I put three drains and have a gentle fall into them. Not too sure if this is part of the issue however when it rains for a long time (like what is planned this weekend) the bottom row of bricks under the DPC becomes water logged and stays wet until weather clears up. I think the issue is due to the fact my bricks are very porous. From what you have said this is not ideal. Therefore is it worth painting on a clear sealer for the first row of bricks to improve the situation. Are there specific products out there.

It seems that your drainage is not disposing of the water as it should because ground is wet and dampness is coming up. Painting surface with waterproofed will simply lock in dampness and I will take longer to dry out. Can you roof over the area?

Simple the bricks on the ground is getting exposed to too much rain. It may be simply the actual rain hitting the bricks directly or when you have constant rain falling gentle over a long time the area where the concrete and bricks meet is creating a bridge. Generally speaking the concrete and draining s very good and doesnt hold much water. Re: Damp Proof Course Rectification 25Jan 07, 2015 4:40 pm B STAR perhaps I didn't explain myself properly.

In that case we are not talking about damp proof curse but weather proofing exposed brickwork and you can do that with clear waterproofer (try Shellby at Bunnings) Foremost Building Expert in Australia,assisting with building problems/disputes, building stage inspections,pre-contract review advice for peace of mind 200 blogs http://www.buildingexpert.net.au/blog Re: Damp Proof Course Rectification 26Jan 15, 2015 9:48 am A lot of brickies and some builders too I suspect like to start the brickwork below or around ground level so it gives them a chance to level up the courses before they are seen above side path level or floor level. Some of the formwork and footings can be a bit hit and miss level wise so it allows them to enlarge or reduce those mortar thicknesses in that area to suit.

Just another argument I will have to have with the builder. Just another issue I will be raising at the next scheduled inspection. Has anyone successfully had the builder pull down brick walls because of it?
