Hi .Thanks for the replies. I don't think the builder has put a DPC in but I will check with him. Fairly certain there is no drainage at all. The wall is on 150mm concrete. There are some weep holes but they are a bit all over the place. One is close to some damp as you can see in this picture. I'm beginning to think that filling it with aggregate and paving is the only way forward here. Even if I do that, the wall may take some time to dry out as it is damp right now.

Yes, beam and block would do it I think. Filling with aggregate would cost around £1,000 from my calculation, which is probably cheaper than beam and block. What if we keep with decking, how do you think we get the walls to dry out and stop getting damp in the future? Thanks

Thanks. My wife wanted hardwood. I had thought of paving it but I think that's 25m3 of hardcore... would you put that much in? I think that should stop the damp though. (And the joists are already done for the decking).

Hi everyone, We've just refurbished our house with a builder who has done a great job on the house and interior. Unfortunately, he followed the wrong plans for a deck and instead of building pillars for a suspended deck, he built a brick and block wall laid on a concrete foundation. It's about 1m up from the ground and encloses a 50m2 area. The builder has filled it with rubble from the house. We've had a delay because of COVID and have not put the decking on top as yet, but are planning that now. However, the deck wall has got damp as you can see in the picture. The builder suggested putting pipes through the wall to let it drain, but don't think it should be getting damp to start with. Any thoughts about this? Thanks, Matthew
