I want to cover an old, ugly concrete patio with resin bonded gravel and have a couple of questions I'm hoping someone can help me with...
First off, the biggest issue is the fact the concrete isn't level....it dips in places up to just under 20mm.
Ive had a look at levelling it with something like Ardex K301, but that stuff is expensive! It would pretty much double the cose of the whole project.
So, am I worrying too much about levelling the concrete?
Can I just use regular concrete to level the deep bits or would that fail once I put the resin and gravel over it? I don't want the gravel to crack or start peeling off.
If regular concrete is ok to use, would I need to use levelling compound to feather in the edges where the new concrete meets the old or would the resin bonded gravel hide it?
The other question is regarding a manhole that's set in to the concrete.
I have found recessed manhole covers that can be filled with whatever surface you're using to make it look much nicer, but these covers are typically pretty deep, and usually quote for use with resin bound gravel. As I'm wanting to use resin bonded gravel, which is much thinner (3mm gravel), is there a way I can modify the manhole cover so I can fill it with the same resin and gravel I'm using on the rest of the concrete?
Do I just fill it with concrete up to 3mm from the top, then use the resin bonded gravel for the top coat or would concrete be a bad idea for filling the manhole cover?
Thanks for any advice guys, this is turning from a project I was looking forward to, to one I don't even know how to start!
