Hi,
I have a bit of concrete broken away from the front edge of my garage floor and have tried to repair it using a strong cement mix and using pva on the old concrete and in the mix. Even after leaving it to get hard (+ 7 days) the car tyres still manage to break the edge off again.
Any advice appreciated (other than re-laying the floor!).
Thanks
Would it be possible to chamfer or round off the edge with a grinder? or you could fit a length of angle iron or something similar to reinforce the edge
Or grind out a larger section and then replace. Use concrete hardener in the mix or even try one of those fast setting concrete mixes for fence posts.
How about drilling to put some plugs and screws into the damaged area before repairing, use long screws and leave the heads sticking out to provide a key between the old and the new, maybe also screw some expanded metal mesh firmly to the damaged area.
