How to lay stepping pavers and pebbles over concrete?

[Ros2]

Hi, I’m wanting to lay rectangular limestone pavers on top of existing concrete down the side of my house, with pebble stones in between and down the sides.   
firstly, can I do rhiis?  Are there any issues, I’m thinking of drainage?   Any advice is appreciated.

Hello @Ros2 

Generally speaking, it would be possible to put a sand base over the concrete and place the pavers over it. The pebbles can then be placed around the pavers. My main concern is that the pavers are technically on a very thin sand medium which means that movement will be very likely. Your second picture shows that your bins are in that area as well, these will not interact well with the pavers as they will tend to push them out of position. You would probably need to move the bins to another location.

Your worry about drainage is quite valid, but if the fall of the concrete path is correct it should drain away from the house. Plus, you have that very large drain at the end of your path. Aside from the pavers possibly moving the pavers can be put into position. This particular issue could be resolved by sticking the pavers to the concrete using adhesive and not using a sand base at all. Just keep in mind that should you wish to remove the pavers it will need to be hammered loose.    

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let us know.

Hi Eric,

Thank you for taking the time to respond to my questions. I like the idea of fixing the pavers to the concrete.  Do you have any particular recommendation for the adhesive?  
I’m having some internal house renovations done and I’ll get onto this task in a couple of months.  I’ll send through some ‘after’ photos!

Hi @Ros2,

To stick the pavers to the concrete you can use mortar like you would with bricks.

The pavers would then help to retain the pebbles in between them.

Let me know what you think.

Perfect. Thanks Jacob.

I wonder whether paving paint might be a better solution for refreshing your sideway @Ros2. It looks like at least some of the concrete has previously been painted.

True, it does seem some have been painted previously.  However, I like the pavers and pebbles look so I’ll probably go with that. There is a raised concrete area near the bins so I think I might use paving  paint in that area.   👍🏼
