Paver Installation
Procedure
1. Paving Stone General Installation
First measure the area you intend to pave. Determine square footage by
multiplying (length x width = square footage), add 5% for breakage and cutting.
Measure lineal feet of open edges, those not up against a permanent structure
such as a house, etc. This will indicate lineal footage of paver required. Draw
a plan on a piece of paper showing all important dimensions. Take this plan to
your supplier so that he can help you determine the proper amount of materials
needed to complete your project.
Using the 3-4-5 triangle method to determine a perpendicular line, measure
parallel lines from the perpendicular line to establish a boundary. Place stakes
every 4 feet to 6 feet and at corners. These stakes should be 8" outside of
the planned edge of the pavers.
NOTE: You can check to make sure an area is square by making sure both sets of
cross corners measure the exact same distance.
2. Excavation
NOTE: Before any digging call your local utility companies to locate any
underground lines.
Using a flat shovel cut evenly to remove sod/dirt to a depth of at least 5
1/8" (13cm) to allow room for 2 3/8" (6cm) paver, 3/4" (19mm)
compacted sand, minimum of 2" (5cm) compacted crushed stone base (more soil
is very soft). If the house is of new construction there might be potential for
settling next to the foundation. We suggest you increase base thickness to
6" (15cm) or a total excavation of 9" (23cm) within 2 feet (1 meter)
of new foundation. Excavation should be 6" (15cm) wider on sides where
paver edge restraint is to be used.
3. Base Preparation
This is very important. The more time and effort you put into the preparation of
the base, the better the project and the longer it will last. Use either
3/4" (19mm) or 1/2" (13mm) graded base material that includes sizes
down to fine dust. This material is easier to compact and will give a tight
close knit surface. Method of Compaction. First, run your plate compactor over
the excavated soil. (Make sure no soil gets stuck to the bottom of the plate
tamper). Each pass should overlap the previous one by about 4". Now spread
your gravel base material out evenly in about 2" layers. If material is dry
and dusty use a garden hose to thoroughly wet it down, this helps make the
gravel faster to compact and easier to rake. Starting around the outer perimeter
start with the plate compactor and again overlap each pass about 4" working
towards the center. You should make at least two complete passes for each layer.
Use your hard tooth garden rake to rake out any unevenness. (Try spreading
material with the rake turned upside down).
When finished with the base it should be very smooth and flat. If you were to
put a straight edge flat on the surface there should be no more than 1/4"
(6mm) (maximum) gap anywhere along the straight edge and the base.
Slope and Grade are important to ensure proper run-off. It is best to plan at
least a 1/4" (6mm) per foot drop, but try not to exceed 1/2" (12mm)
per foot.
4. Sand Setting Bed
NOTE: It is important to keep your sand dry. Always keep your sand covered in
case of rain.
Do not attempt to level any area or surface irregularities with the sand. This
will result in an uneven surface and unwanted settling.
Lay your screed guides 1" (25mm) electrical conduit, 1" strips of wood
or other suitable rigid 1" guide) 4" to 6" apart and parallel.
Work from side to side with your screed guides, screed a 10" section of
sand. You will use you 6 ft. to 8 ft. 2" x 6" to loosely spread the
sand and to strike off any excess. DO NOT walk on or work from your screeded
sand. Do not worry about voids that screed guides have left after you have
removed them. You will lightly fill them with sand and trowel them smooth as you
are laying the pavers.
5. Laying the Pavers (Instructions for Small Areas Only)
Starting from a permanent edge such as a house, driveway, or even a piece of
paver, lay your first pair starting from either side. (As you start laying
pavers, work from right to left, then left to right and so on, one row of pavers
at a time.) Set the pavers lightly onto the sand, NEVER press them or hammer
them in. Be sure to allow 6" (15cm) to install paver on the open sides
later. If you are starting with paver as a starting point (read #7 now), every 4
feet or so run a string line across front of the laying edge. If there are some
pavers lagging behind go back about 3 rows of pavers and using a small pry bar,
wedge between the pavers and pry the pavers forward until they are in line
again. Do not worry too much about gaps at this point, they will even out during
tamping later. Many different laying patterns are possible, but herringbone
provides the best surface interlock.
Set the pavers hand tight, but DO NOT use a hammer to adjust the pavers or set
them. If you are doing the project over a couple of days, cover the entire area
with plastic overnight if rain is expected. Do not lay pavers over the 6"
(15cm) extended base area where paver is to be set later.
