can i lay paving stones over our existing concrete patio?

Answer 1

Our front porch has a concrete base with brick pavers set in a basket weave pattern. I believe they were set with a tile like thin-set and then had brick mortar put between the bricks.

We've used this porch for over ten years and it has held up very well. If you would like a pic, contact me.

Answer 2

A concrete slab would make a real good base under stone, but first study out the project. What type stone do you intend to use ? If it's real thin like slate, lay it in mortar spread on the concrete you now have.
If you intend to use a thicker type stone, you'll have to consider the finish height of the patio. If height is of no importance, go right ahead. You already have an excellent start with the concrete slab.

Answer 3

You can but:

Is your patio solid, and does it have cracks in it. If so, then it is a very good chance the cracks come Thur and crack the paving stones.

It is a must to repair the patio cracks first. Or redo the patio all together. I know, I know, someone is going to say it OK. The cracks doesn't matter. Well go ahead put the paving stones on top and see what happens this summer. I did and learn the hard way. Do it right the first time.

Just given you my advice and what happen to me.

Answer 4

This is an interesting idea.

Typically, pavers are put in a bed of gravel to keep them nice and tight, but a concrete base *might* work, as long as:

1. It's level.

2. The height of the pavers over concrete isn't too much.

3. You are in a warm climate. If you have freeze/thaw cycles, water would get in between the pavers and concrete and probably ruin the concrete base.

I say, go for it--if these 3 things work. The worst that happens is you have to tear out the concrete later, rather than sooner.

Answer 5

Yes you can use the stones.Before you lay them use sand to set them in.Stop sliding,rocking,help's get them level.
