Our garden is on an extreme slope, so I got someone in to landscape it. Unfortunately after one winter the walls are a complete mess. I'm not getting the person who did it back, so I am after any advice on fixing the problem.
The walls are made from breeze blocks and it seems that water is coming through from the inside and destroying the rendering. What would be a good way to fix this? I'm not too worried about it looking perfect, I just want it sorted. I've played around with the idea pulling all of the rendering off and painting the breeze blocks, but I'm thinking that will be a nightmare job as breeze blocks are quite soft.
Could I do something to the inside of the walls to waterproof it, or could it be that the water might be coming down from the top? Any advice would be great!
