My family and I are looking to build a low lying deck over our concrete patio but we've run into a few problems with the idea.
The first is that the concrete slopes down and there's at least a 20cm difference in height between the highest and lowest point. We were unsure about whether it would be a better idea to try and level the ground out first and if so, what the best way to go about doing so would be. I thought about using leveling compound and my mum had suggested using wedges to offset the slope to keep the timber level.
The second is that there is less than 10cm of clearance between the floor of the house and concrete outside, and even less at the highest point. I presume that to build a deck it would be higher than the floor of the house which is fine, but just wondering if that would present any additional issues.
Another point of note is that there has been a small raised structure built alongside the house to level out the slope on that part of the patio in order to place things on it, have attached an image that shows it along with the slope. Was thinking of using that as a guide if I were to use leveling compound.
Been doing a lot of browsing in these forums and have gained a lot of insight but still very unsure. I would really appreciate any assistance in clearing up my confusion and I give many thanks in advance :))).
