Installation Guide
Preliminary Planning
Initial planning
and preparation are key factors that will ensure a
successful and lasting paving stone installation. Proper
planning guarantees fine quality work and makes everyone's
task easier.
Sketch a detailed diagram of the area to be paved, including
all measurements required to calculate the amount of
material needed. The area being paved should contain some
form of edge restraint.
Certain equipment
is required to complete this work adequately. You will need
a rake, shovel, tape measure, coarse bristle broom, masonry
string line, line level, mechanical plate tamper, and some
form of stone cutting equipment. Pavingstone Manufacturing
can assist you in obtaining the necessary materials and
equipment needed to complete your paving stone installation.
Base Preparation
Before you dig call the following companies to ensure your
safety: Hydro, Telephone, Gas, Cable T.V. they will provide
you the location of underground services.
1. Remove old
pavement and/or existing soil, then excavate to the proper
depth depending on the type of traffic.
2. Spread gravel
(also referred to as 3/4" crushed rock or equivalent),
uniformly throughout the excavated area. Using the
mechanical tamper, compact the entire area evenly. A
sprinkling of water, prior to compaction, will increase the
density of the base material and control dust. Do not
compact the base material in layers of more than 3 inches.
NOTE: Prior to base preparation, water run-off and grade
detail should be considered.
3. The compacted
base must be uniform and should conform to con- tour of
finished job. The elevation of the compacted base should be
uniform 3 1/4" to 3 3/4" below the finished paving stone
surface.
4. Following the
completed base preparation, edge restraints are installed to
prevent lateral movement of interlocking stones and to
enhance the aesthetic appearance of your installation. Edge
restraints may be set in a manner to sit flush with, or
slightly, below your completed paving stone surface.
Granular material is used as backfill on the outer edge of
restraint which meets sod or softer material.
NOTE: Care
should be taken in determining the width of the area being paved
in order to minimize cutting of pavers, and optimize the use of
edge pieces.
Screeding:
5. Spread 1" to 1
1/2" coarse sand evenly over the compacted base to establish
a bedding for placement of concrete pavers.
6. Screeding must
be done to ensure that an even bedding surface is
established. A screed board (i.e. 2"x4") is used to smooth
the bedding layer to the shape of the completed surface. For
distances greater than 12 feet, use a screed guide to level
the bedding layer. Avoid walking on the screeded surface.
Installation of
Paving Stones:
7. Commence placing pavers on the screeded bed in the
pattern you wish to use. It is important that the pavers
being installed are being taken from 2 to 3 bundles to
ensure a proper colour dispersion. Start installation of
pavers at the edge and in a corner if possible. This will
maximize the use of edge stones and minimize the amount of
cutting.
8. Hand place the
stones close together. Spaces between individual units
should be consistent with an allowable maximum of 1/8". With
the installer standing on the laid paving stones, the next
row is placed. The occasional use of masonry string will
ensure that your installation pattern will continue to run
true throughout the project. To verify accuracy, the string
should run along the front row of pavers. A screwdriver is
used to move the pavers into proper alignment.
9. Any paving stone
cutting should be done upon completion of laying your paving
stone pattern. Using a stone cutter or masonry saw, stone
should be cut to fill the spaces. If cut pavers leave small
gaps, these can be filled with jointing sand.
10. Once all pavers
have been placed, sweep the entire paving stone surface
clean in preparation for tamping. Sweeping also aids in the
removal of any foreign deposits that are on the pavers.
Job Completion:
11. Using a mechanical plate tamper, begin tamping the
entire paving surface in both directions until the surface
is bedded down uniformly.
12. Broadcast
jointing sand over entire paving stone surface. Begin
sweeping sand to ensure that all joints are completely
filled.
13. Leaving all
excess jointing sand on the paving stone surface, tamp the
finished area a second time and continue sweeping jointing
sand and compacting until all joints are completely filled.
14. You may decide
to use a paving stone sealer to enhance and protect the
natural beauty of the paving stone. It is recommended that
you seal the pavers several months after installation.
Contact Pavingstone Manufacturer to obtain the proper type
of sealer.
