Step 1: Remove the sunken pavers

Pry up the paver with a thin screwdriver,
pounding on adjoined pavers
to vibrate packed sand loose.
After a few years, paver block patios
and walkways often develop low
spots. However, these areas can be
brought back up to grade with a few bags
of sand, a length of pipe and a screed
First, remove the pavers from the low
area. If they're packed in tight, use a
screwdriver to lever the first paver out,
levering each end a little at a time and tapping
on surrounding pavers until you can
pull out the paver (Photo 1).
Step 2: Lay in a screed pipe

shallower than the depth of the pavers.
Make a screed board long enough to
rest on the level pavers around it. Then
notch the ends 1/8 in. less than the depth
of the pavers. If the area is large or against
the house or grass, set a screed pipe along
one side and level it against the pavers
you're matching. If you're trying to match
a sloping walk, shim the level at the downhill
end to match the slope (Photo 2).
Step 3: Add sand and level it

Add sand to the low area, then level
it by pulling the screed board along
the pipe and the pavers.
Fill the low area with coarse, all-purpose
sand, then screed it level (Photo 3).
Use a trowel like a spatula around the
edges to scrape away any excess sand.
Step 4: Reset the pavers

Remove the screed pipe and set the
pavers back, tapping them down
level with a board.
Brush any old sand off the sides of the
pavers, then set them back into place and
drive them down until they're flush with
the other pavers (Photo 4). Spread dry
sand over the pavers, tamping and sweeping
until the joints are completely full.
