Condition of bricks below DPC

DougMLancs

So thanks to advice from forumites, I borrowed an angle grinder and hired a breaker to carve out a trench in our driveway which had been put in level with the DPC. Still got some soil to remove but already the condition of some of the bricks and pointing below the DPC is concerning and the airbrick is almost crumbling away (it was blocked up when the CWI was installed in 2011 I believe).

Is this something I can DIY? I’m confident with pointing but if several bricks need replacing from water saturation then is it a job for a builder?

You could replace them yourself. The ones below DPC look like splits, as they got the brickwork below a bit high. You will probably find the DPC breaks up, so stick a new piece in.

Cheers! I’ll be glad when this wall is all finally sorted out and we can stop wincing every time we get driving rain

Just noticed you have CWI. If it's beads, you might find they start to fall out.

Ah it’s ok- it’s mineral wool but it will be useful to spy on the condition of it nonetheless
