A Practical Guide to Laying Paving
Base Preparation
1) Remove topsoil from the area to be paved.
2) Base materials may consist of granular materials (Crushed
aggregates or limestone screenings) to be placed in a 6" layer. The
thickness of base will vary with type of soil subgrade and climate,
colder climates may require thicker bases.
3) The base layer should be thoroughly compacted with enough
water to aid compaction, increase density and also control
dust.
4) Once the desired compaction has been achieved place a 1/2"
bedding layer of loose sand on top, ensuring that the base is level
by using a string line or screening board.
5) Patios should be laid with slope to drain off rain water.
This slope (away from buildings) is normally a drop of 1 " for each
yard in length.

| Laying Paving
1) Choose the design that you wish to lay, then starting in a
corner carefully place the first slab in position and gently tap
down using rubber mallet.
2) The bedding layer of loose concrete sand allows for leveling
the surface of each slab which may vary from piece to piece due to
their texture.
3) Slabs may be laid with up to 1/2" joints and filled with dry
sand on completion of installation.
Under no circumstances should a mechanical compactor
be used directly on the slab surface

Laying Circles and Other Features
1) To lay a circle, follow the paving laying instruction left,
except start at the center of the circle and work outward. Dry lay
each ring before fixing into position.
2) Where a circle is laid as a feature within a paved area, use
the corner accessories to square up to the paving. You may want to
lay a few courses of paving before you start your squared circle to
avoid cutting at the edges. When completed, sweep masonry sand into
joints. (Polymeric sand is recommended) Do not use vibrating plate
on surface.
Laying Chelsea Cobble
1) The main units have irregular edges to give the impression of
a number of cobbles placed onto one slab. Rotate the main units to
randomize the cobble effect. Use the wavey edges to place the slabs
together. If you require a squared off effect use the side and
corner units accordingly. Fill the paved area to make the joints
appear invisible.
