I did my apprentership for a damp proofing / woodwork and dry rot firm . The chemical injection into the brickwork to replace the DPC was said to be a bit of a show boat and didn't do a lot . The main things done to combat the problem where removing the old plaster to 1m high and 1 m past the last known problem and re render with water proof render . On the out side of the wall dig away anything touching the wall above the dpc line . We would normally dig a gully about 200mm wide and back fill it with pea shingle so water would drain away .

Seen a new house built with no DPC ( damp Proof Course) so the brickies would come and Stilh saw about metre along the brickwork every day and put a bit of DPC in then repoint and wait till that set before doing the next bit , you could only do this on the inside leaf of brickwork if you lifted the floor first , DPC level should be below the floor joist if the floors wooden.

You can hire the kit to inject the walls and do it yourself. The only drawback is if you need an insurance backed guarantee for mortgage etc. For replastering, I'd use renovating plaster, which contains salt retardant to stop stains coming through, but has better thermal insulation than cement render, and it's not rock hard, so it's kinder to your brickwork and you can bang a nail into it to hang a picture etc. I didn't bother with the injection on my place, just replaced ropey plasterwork with renovating plaster - although I didn't have serious damp problems to deal with.

De-humidifier works a treat. They cost about £100 for a decent one and I put it on when drying clothes inside/ excess moisture in the flat.

Fair enough. Seeing as this is on topic - has anyone got any tips for dealing with moles in the garden? The scissor traps aren'tdoing the job.

You will need a big shovel and night vision goggles and some patience :thumbsup:

We had two walls in our basement damp-proofed 15 years ago. The injection pump was no more specialised than a big plant sprayer which would have worked equally well. It looked a pretty simple operation really, but hacking off the old plaster to waist height created a huge amount of rubble.
