I have a slab of concrete in the corner of my garage that needs removing. It is approx 1.2m x 1.2m and about 25cm deep. It is in two layers - the top 8cm or doesn't have pebbles in the bottom part does.
I started by using a chisel attachment in my SDS drill, the first part went quite well, the first 20cm or so was laid on top of the garage floor so it came away easily but after that point it must have been lower. It is now harder to remove and won't leave a nice flat finish - but I can sort that after.
For now though the question is - how do I remove the rest! I've only done a relatively small portion and it is killing the SDS drill! It's getting hot during use and the brushes are sooting up to the point that it won't work until I take them out and file them down - I've done this twice now but would prefer not to destroy the poor thing.
Is there any easier way. I can't really hit it with a sledgehammer with the solid floor underneath. I've read about expansive grout but would be worried using that with the 2 walls either side and the floor below.
So any ideas?!
