Pavers over concrete slab and new foundation.

Posted by Deerfieldponder 5deerfield (My Page) on Mon, Mar 21, 05 at 11:44
I have a 12' by 11' concrete slab that is in good shab. I want to cover it with pavers, but I also want to make the patio larger, like 16' by 12'. The slab is flush with the lawn. I have about 2 inches of topsoil over clay on the grass that will be covered. My current plan is to put in 6" of gravel, than and inch or two of sand to make the foundation larger and reach the height of my concrete patio. So do you think this will work in a cold climate, should I choose another surface material? Maybe large concrete tiles would be easier to get flush. What would be good for edging since the patio will end up 2-4" above the ground? Am I doing a quick fix that will leave me with long term problems?
Thanks for any ides??
Cheers, Matt.

The gravel will be your best bet. The deeper the gravel the better off you'll be from heaving and sinking effects. Compact the gravel as much as possible by doing it in 2-3 inch layers.
Also does your existing patio have a drain? If it does than you might have a problem with the sand washing away over time.
You can find edging where you buy you pavers, it is generally a poly material and is held in with 9-12 inch spikes. BTW you don't have to use a spike in every hole.
After that is all done you'll have to raise the level of the lawn or beds to match the patio height.
Or.....take out the patio and put down gravel and do everything the correct way from the beginning and have "piece of mind".
Good luck |
