Bricking over a concrete path

Question

I am currently planning my garden design, I want to brick over the current concrete paths so that new paths will all be uniformed with the exsisting paths.

I can't afford to do all the paths at once, so want to make sure that when I do the paths, the borders, lawn area and patio are all at the same height as it needs to be wheelchair friendly.

So my question is how much height do I need for bricks on top of concrete? Guessing its just sand then the bricks and then sand in the gaps but not sure the deph of base sand needed.

Any advice welcome. Thank you.

I recommend between40-50mm of  sharp sand. Also about all being a level base for your garden, If there is any differences in height you can ramp up slightly or slope down to make the height differences still accessible for wheelchairs.

It would be best practice to just brake up the existing concrete to help with drainage then if your talking about block/brick paving around 40mm of sharpsand as the bed.

At least 30-50mm to give you good strong base. 
Or if you concrete is level you could use a wet slurry mix that is really strong .but most concrete unless it’s had a polished over it has lumps everywhere, hope this helps
