Am pouring a small (1700lx 1600w x 180d) slab for a pizza oven in the backyard.
I've read that you should vibrate the concrete slab to help remove air pockets. How much does it need to be vibrated? I've cobbled together a rough vibrator like I read on line of a piece of rebar attached to a drill and inserted in a piece of pipe. It certainly vibrates...
Would this be sufficient?
I'll be using it for both the slab and for core filing the besser block stand.
Cheers
Shane
