Browse Forums Paving & Concreting 1 Aug 24, 2021 11:55 pm Hi All, I would like some advice about building a bench/seat next to my pool. The plan is to try my hand at a DIY job (cannot afford to pay someone). The bench would be about 5 meters long, 50 cm high and 50cm deep. It would be against a shed wall so only needs to have one side and the top with panels. My plan is this: * Dig 6 holes and put in some stainless steel stirrups. (stainless as next to pool which is salt water) (2 each end and two in the middle) * Fill with concrete - as there will only be 50cm between each pair of stirups, the concrete would be joined up for both. * Use some 90mm posts (very short) and then some other framing pine wood to make a structure * Attach some fake wood decking boards to the side and top. (3x140 on the side and 3x140 on the top) * The frame nor boards would not touch the shed at all. My problem is that when I have started digging down, there are some pool pipes, vine roots in the way as per the photo. I am unsure if i can simply pour concrete right over all this and it will both hold it's strength and also not crack/affect the pipes over time. Would I need to wrap the pipes in some type of foam insulation to allow for a little bit of expansion etc ? (the pipes might have 50C water from the heating). Should I chop away the roots or would they be ok (as i like the vine). I suspect also that I will need to dig down deeper - maybe 30cm or so? Should i try and attach to the concreate on the shed slab or pool tiles slab or just have it free standing?
