HOW TO INSTALL
PATIOS AND WALKWAYS
Concrete Overlay – (with or without expanding
project size)
For all Patios and Walkways
The base is the most important step in your patio and walkway projects.
MATERIAL REMOVAL GUIDE
How deep you need to dig is determined by adding the thickness of
the following components:
EXAMPLE Thickness
Leveling Sand 1/2 Inch
Paver Thickness* + 1 3/4 Inches
Brock PaverBase + Approx. 3/4 Inch
Dig out this many inches
below your current level = Approx. 3 Inches
*will depend on the paver you select.
STEP 1
PREPARING YOUR CONCRETE
OVERLAY WITH EXPANDED
PROJECT AREA
Most commonly this is removing a grass area that is around your
current concrete patio. Determine how much to excavate using the
example below. Remove the grass to desired depth (skim rather
than dig deep) from the surface of your current concrete slab for
the area of your extended patio.
STEP 2
LEVEL AND COMPACT THE BASE
Using a hard rake and/or shovel, compact and level the area and
make sure it follows the slope of the concrete pad. The ground
should be tightly compacted using a hand tamper or plate
compactor. The slope should be about 1/4” per one foot of distance.
It is helpful to pull a string line so you can check your slope. To run
a string line, attach a string to a fixed point on the house side about
3” above the surface of the patio, and pull it tight toward the
outside edge of your new patio area. Attach the other end to a
landscape stake in the ground making sure the string it tight. Use a
level and ruler to create the desired slope. For example, the patio
should slope 2.5” over a 10 foot distance (Diagram below). This will
ensure that the patio moves water away from the house.
The area should be as smooth as possible, making sure to get rid of
high and low spots to within +/- 1/4”. This is now your compacted
base. Congratulations, the hard part is over!
