Do you have the necessary amount of cat turds to add to it?
When I was installing a mooring point for a boat, which was half and

fine for that job, but would not be good for, say, a bridge, and

That's odd - when I was researching ferro concrete boats a few years

on a sandy beach then use it. Mind you you can't do that in this
country as the bit from low to high tide belongs to the crown so the
Queen could bang you up the the Tower G
