Existing slab
Hi all,
I have an existing slab of concrete in the backyard.
It is about 3.5m x 2.5m and about 5" deep.
I have a pier that I bought off Lewis with four standard 13mm holes drilled through the base for installation.
What is the best way of installing it to the slab?
Do I hire a hammer drill, drill the holes and then just nut and bolt it into place?
Or, am I better off putting a new slab in especially for the pier?
Advice gratefully received.
