Need some help ----- please - Pavers over concrete

[joefar75]

I had to make the width of the driveway 2 feet wider on both sides.
I poured a 4 inch concrete slab and I had the intentions of laying the pavers over the slab with Mortar.
But Im hearing that this is a bad idea.

What do I do now? Concrete is already layed.

thank you in advance.

Do you mean Block Pavers? Yes that is a bad idea, if it's a solid Concrete slab, you could lay Paving slabs, on a full bed, but not block paving.

[joefar75]

Yes. Block pavers.

So what should I do?
any suggestions.
I was thinking about just using mortar on the outer border, so that I would lock them in, but then using sand in the middle?

I feel like kicking myself in the ass here.

I have layed them on semi-dry screed type consistancy over a slab before but it was a small area and quite sheltered. 5 years on they are still ok.

It's not the best method but can be done.

Rigid block paving

[joefar75]

These are'nt so sheltered.
There's nothing covering them, and a car will be driven over a portion of the job.

I' found a product called Curve-Rite which is a Heavy Duty 2" aluminum edge. I think Im going to fasten it to the concrete, and then lay the pavers in the sand.

I figure the worst that can happen is that they break apart, and at that point I'll just lay them in mortar and hope for the best.

You have to think about water retention in the area. Have you got sufficient run off? Where is the water that will get between the blocks go? How are you going to joint them? Because simply trying to lay them like conventional Block Paving is going to lead to lots of trouble later. Have you bought the blocks, if not, don't, use Slabs instead, you could use Sandstone on a solid bed, not going to cost much more (presuming your after using 200x100 blocks), and will look a lot better.

[Carberry]

If you lay it as you are suggesting it will fail.

Big time.
