Remove coating on concrete driveway

[pokop]

Hi there, We just bought a house which has a driveway that looks like it was resurfaced with something, probably to cover the cracked concrete underneath. Anyways that something is now crumbling and lifting on places to driveway coating removal Brisbane, so it looks terrible. So my question is, does anyone know what the stuff is that's on the driveway? And secondly how can I remove it? Thanks
