I have a concrete slab of about 1.5m wide and 5m long. I want to put a solid colorond fence (light green) near the middle of the slab, along the long side. The fence is about 1.8-2m high, 4m long. There will also be an aluminium gate (dark green) to finish that 5m section. The slab is 10cm thick.
Is it safe to use post bases like the one in the attached photo? I'm thinking of having 3 posts (blue).
Thanks.
