Small ramp on path

[LazyDozer]

I have a patio that sits 4cm above an existing concrete path 90cm wide.

This is a trip hazard and want to blend in the patio to the path by constructing a concrete ramp.

How long should this be to safely blend in the height difference?

Also how do I prevent the ramp falling apart? What mix should I go for? Do I add fibreglass into the mix? Should I cut grooves into the path with an angle grinder to key the ramp?

Please help .

If you want a ramp, to wheel things over it will need to be min 20cm, but if its just to stop a foot strike, then you can round it off. Or buy an ending stone.

If you go down the concrete route a couple of zink screws in to the concrete to help it key will help. Just don't try to smooth the ramp completely in to the path, its likely to chip off. Of course the other option is to Kango the end of the path off and create a new integrated concrete ramp.

You could use riven slabs to top the ramp , safer in wet or icy conditions .

Thank you for the replies and great advice. I will attempt to incorporate them in as best as possible - hopefully without messing it up
