The damp course on the back of our house is at the same level as the concrete walkway. This is two low (should be about 6" I believe) and causing a small amount of damp in the house. Can the damp course be raised? and if so any advise on where to find someone to do it?

the dpc on a house can "cause" damp. on older houses the mortar can crumble and fall out of the back of the brickwork into the cavity ending up sitting on the dpc. this bridges the gap so water can cross from the outer skin to the inner. so it may be worth having a brick removed (where you have damp inside) to check for this. if this is the problem no amount of money thrown at any other cures will work and could make matters worse. worth lowering the pathway all the same. treat the "cause" not the effect. so id the cause first.

its not the damp course that is too low. Its the concrete path that is too high. If you breaking up the concrete from your wall to say about 3" away. Then in its place put some pea gravel down. This will stop the damp penetrating through your walls. whoever put the path down was in the wrong, not the builders who built your house.

It is a messy and expensive job to raise damp course but there are treatments you can get and apply on outer and inner walls to prevent damp from coming in. Another alternative is to lower path. Isuggest you try local builder providers.

there is nothing wrong with your damp coarse your problem is your path is too high ..the damp coarse is normally level with your finished floor level ..the exterior ground level should be two coarse of bricks below damp ..so your path must be lowered .. or moved sideways away from the house by at least 200mm ..and the ground next to house removed ..go down 3 coarses and fill with gravel up to two coarse below

don't know about raising the damp course, but you could lower your path. it should be OK if it is a brick height above the path. contact a local builder for advice.

sounds like the path is too high, you can dig it out and repour it lower, or...
if you have a brick house get it injected with silicone,
if you have a plastered house chip about 12" above ground level and replaster with a waterproofer admix like medusa in the render. hope that helps.
