Hello everyone, I'm becoming increasingly worried about a project I'm working on. I picked up the project halfway through, and the plans had already been made by a much more experienced builder than myself, so I just followed them.
I extended the air bricks under the soon-to-be tiled patio and installed a threshold drain around the house. My concern is that the level of the patio is less than 10mm away from the DPC. I was led to believe that installing a threshold drain was satisfactory to bring the patio to this level. However, as far as I have found in my research, having a threshold drain is irrelevant to the distance you can put a patio below the DPC.
Can anyone shed some light on how I may be wrong and the original builder might be right? Or, what the reality of moving forward with this would actually be? In other words, what is the real risk to the property if I continue with the current plan?
Thank you in advance for your help and expertise!
