My driveway is wearing and I want to replace it with interlocking
brick. Can I avoid tearing up the pavement and use this as the base
(re-tamp again) for the sand then brick? Tearing up of pavement would
be a hard task for an old timer like myself. Disposing of the old
pavement would be equally as hard on a fixed income. This will be a DIY
Well you did not tell us what your current drive is made if. I have
seen gravel, concrete, asphalt, etc.
My question is have you considered that you would be adding the at least
a couple inches of sand plus the height of the brick. Do you want your
drive that much higher? I would also want to make sure you have good
drainage through the drive. From here I can't tell. :-)
I don't think I would want to do it on asphalt. You want drainage to
go down through the base into the soil, not run off. With an asphalt base
the water would go there, then it would be stopped. I would expect
problems. I can't help by think the extra height would have to be a problem
I do a lot of strange things with pavers, I got a truckload for free.
I built a fireplace and tiled the walls of my shed and outside bar
I agree if he is in a freeze thaw place I would worry about them
heaving up but if he is one of us sub tropical folks I would just
stick them down with thinset, like tile and be happy.
Besides the height issue of adding at least 6 inches to the surface
height, I would think there will be problems with the pavement trapping
water and heaving. Do you live in a hard freeze area?
How is the drivevway "wearing"? There may be resurfacing options. Many
places will hot-top the driveway, which is essentially a skim coat of
new asphalt. It works OK, and can buy you a bunch more years on aging
There is also the tar and chip scenario which may give more mongevity than a
skim coat. One other issue that I would be concerned about, Ty, is water
washing the sand from between the pavers. Since they will be above grade on
the edges the joints which terminate there will tend to shed sand. That
will probably progresseively worsen and creep inward making the pavers
loose. Then, you're out there resetting some pavers every couple of years.
Now, that may be acceptable maintenance for you but I thought that I'd bring
it up. Good luck with the project and post back with your progress.
