Hi. We are hoping for some advice on a possible solution to rising damp. When we bought our Victorian semi a few years ago, we were told that we have some issues with rising damp and that we should chemically damp proof most of our ground floor. We have not seen any actual signs of damp, so recently had a second opinion from an independent damp specialist. His view, which makes more sense to us, is that the concrete that surrounds our house at the front and side of the property is too high and that it is likely covering the original damp proof layer (the concrete goes up to the air bricks). His solution is therefore to cut a narrow channel against the house to just below the original damp proof course and back-fill this with pea-shingle up to the damp proof course. I was wondering if anyone had any advice/experience about doing this work and if so, whether they could recommend any builders who have some experience with this? Thanks!
