I have a small job to open up some concrete steps for inspection. Basically i have been requested to break out a section of a concrete step to a depth of 100mm. This wouldnt normally be a problem but there is stepped brickwork to either side of the steps and this has to remain undisturbed. Therefore i am looking to see what the best way of doing this is. The only method i can come up with would be to score the concrete to a depth of 100mm with a stihl saw at regular intervals over the width of the step and then use a breaker to then break out these sections. However if there is a better alternative available i would appreciate being advised. I asssume i will have to use a vibration damped breaker if this is the only method available. Cheers.
