Paving Slab - Trip Hazard

[M8EO]

Hi All,

I've laid a patio in the back garden. Happy with the result apart from one slab in the centre which is not flush and is causing a trip hazard. My own fault when laying it.

I'd like to remove the high point so it's less of a hazard. Of course, I could take up the slab and relay however if possible I'd like to avoid having to do that.

Would it be possible for me to take a breaker drill + chisel bit and chip off the high point by hitting the slab parallel to the ground? They are sandstone slabs which I've heard can be 'flaked' off. Has anyone tried this?

Thank you,
Alex

You could probaly do a better job with an angle grinder. The alteration will probably be a different colour until it weathers in again though.

That's a good idea actually. I'd feel more comfortable using a grinder as it avoids hammering/jolting the slabs which could break their bond with the mortar.

I'll give it a go and, as you said, hopefully it will weather out over time. Thank you!

If they aren't stuck down you'll probably be able to lift it out with a couple of these:

If you're going to grind it, consider:

..and also I recommend to "run it in" by using it to shape some waste stone or concrete first, to get rid of the paint and soften the profile of the corners on the cutting wheel. When they're new the thing being ground can end up a bit notchy. Also good practice

Great - thanks very much! They are all stuck down and grouted in so I'll be trying the grinder - thanks for the advice.
