1.
We don't simply pave over the problem. We remove the existing surface down 6 1/2" - 11 1/2".
2.
Installation of geotextile fabric to stabilize aggregate base.
3.
Then we install 3" - 8" of crushed aggregate base to create a firm but flexible foundation.
4.
Next we add a 1" layer of sharp-angled bedding sand to lay the paving stones up on.
5.
Individual paving stones are then placed by hand into the bedding sand, to ensure a perfect fit. Then a plate vibrator is passed over the stones, locking them into place.
6.
A layer of sand is swept over the paving stones. We pass the plate vibrator over the surface a second time, forcing the sand into the joints from the top.
7.
Finally, we place concrete foundations to protect the paving stones from shifting. This completes the permanent interlocking process.
