Browse Forums Building Standards; Getting It Right! 1 Dec 21, 2020 6:56 pm Hi everyone, I just had a new patio installed. Water mostly flows nicely Away from the house apart from a couple of pavers that are not 100% flush with the others. In heavy rain there is a couple mm pooling. I am in two minds about getting the landscaper back to fix it. I am paranoid about damp coming in the house. I’ve been reading about DPC and I am assuming my house has it. It’s 20 years old. It has weep holes amd I believe from my research that DPC is usually just below them. The pavers start 2 bricks below the weep holes. I cannot see any visual signs of DPC on the outside. I do see some in my garage though. Will my house be ok as it’s well below the weep holes? 150mm below to be exact. Does my house have DPC? Does this protect it from water?

The DPC was suppose to be visible back in the day but it wasn't always. Of interest...Many builders now have a performance solution written into the contract that allows the brickie to recess the DPC...not that I for one agree with it but it is what it is. For a performance solution to be certified, it has to comply (in the opinion of an industry expert) with the performance requirements found in the NCC. 3in1 Supadiverta.
