We laid a slab for a huae today. The pumper layed it so wet that it is sagging in some spots. At about noon they wanted
rent a buffing machine. As they were floating it they were making it worst. I know of a machine with grinding stones that would make it somewwht flat. I left when they where renting the float machine because I thought It would just drop through the slab. This is a project for the homeless I thoght it would it would be better to float let it dry gring and float. By the way 1500 sq no mesh just rebar on the corners. Four feet above grade. #6 mud all at once??
