Location: UKHi. I'm looking to build a concrete artificial rockpool (basically a giant concrete vertical plantpot), similar the picture below, and am seeking advice on how to construct this and how to make it strong enough.https://ift.tt/2Esw47X https://ift.tt/2JqGTLt my research so far I'm thinking - Make a model of the shape from polystyrene. - Layup fiberglass over the polystyrene, but just make a mold for the fronting outside shape (ie. not the internal pool part), like this https://ift.tt/2ICxqzB - Then make a seperate mould for the internal pool, which can be pressed into the wet concrete in the mould to make the rockpool depression. - Embed fixingsI'm new to this so would really appreciate advice and comments. The main tasks I'm worried about are shaping the foam to get this half diamond shape, whether i'll need to add rebar / steel mesh within the concrete for strength, and how to remove the mould after casting.Thanks! via /r/DIY https://ift.tt/2qc4uqz
