As
you might expect, the secret of a long-lasting patio lies in a good
base for the pavers to rest on. How thick a base depends upon the
soil; low-lying, wet soils need a thicker base than well-drained soil.
Three inches of well-compacted, crushed stone should be enough. However,
the type of base material available varies from region to region.
Local paver dealers can reccommend a suitable base and help you figure
out how much you'll need. They'll also help gather and perhaps deliver
your other supplies -- washed concrete sand, edge restraints and pavers.
Seriously consider home delivery... this stuff is heavy.
A mechanical
vibrator plate ($60/day rental) saves a lot of hand labor when compacting
down an aggregate base. Later, you'll want to pack down the pavers
too, so it will be well worth the rental fee. It's a heavy machine,
for adults only, but is quite easy to use. For very small patios,
a hand tamper will be enough (You can make one by nailing two 12-in.
squares of 3/4-in. plywood to the end of a 4x4).
It's
worth being a little fussy about flattening the base and making sure
it slopes just right. Your patio surface will conform to the surface
of the base, showing every dip and rise.
