• Straight board • Straight edge •
String (set up string lines) • Trowel •
White washed sand • Yellow sand |

1. Excavate and spread clean yellow sand
Ensure area to be paved is free from vegetation and debris and
is level with clean sand
|
2. Rough screed
Spread about 50cm of clean yellow sand over the area. level it
off lightly using a straight board.
|
3. Compaction
Compact the area until ground is firm using a mechanical plate
compactor which are available at all reputable equipment hire outlets
on daily rates. Then spread 50mm minimum of clean yellow sand and
spread out to create a bed for paving.
|
|
4.
Setting channels
Hold the straight edge from the benchmark to the line fall point
and level off a smooth channel to lay a screeding iron. You can
use your spirit level to do this. Repeat this about two metres away
and lay another screeding iron.
|
|
5.
Setting Levels
Find a 'benchmark' level as close to the house as possible. The
paving must fall away to a line fall so that water can run off.
The ideal fall is 25mm over 3 metres. If you use a spirit level
to do this, the inside of the bubble will be against the outer line.
The level will be used for the fine screed.
|
|
6.
Fine screed
Move the straight edge along the screeding irons moving the sand
away and filling in any holes as you go. Repeat in area until complete.
When area has been completely screeded lightly spray the area with
water careful not to disturb the ground. This will create the final
level to lay the paving.
|
|
7.
Set out
Set up a few string lines about 2 metres apart at a right angle
to the building. The edges of the paving must lie against the string
lines to make sure the job is square.
|
|
8.
Laying
Commence laying pavers to desired pattern on sand and tap down
lightly using a rubber mallet only. Use the string line at intervals
to ensure your pattern is straight. A gap of 2 to 3 mm is required
between each paver for sand filling. (Note pavers should not make
contact with each other.)
|
|
9.
Cutting
Using a diamond blade brick saw cut into fill all part pavers and
curves to suit the pattern chosen.
|
|
10.
Edge restraints
This will ensure that your paving will not move. This is best done
by lifting the leader course of pavers and scraping about 20mm depth
of sand from the edge and then laying a cement mortar slightly over
filling and then tapping the header course back in to position using
a straight edge to maintain a straight and level line.
|
|
11.
Joint sand fill
Using a hard bristled broom spread and sweep whitewashed sand over
the paving, filling in all joints as you go, to create a locked
system. Sweep away most (not all) of the excess sand.
|
|
12.
Final compaction
Again using a mechanical plate compactor, lay it over a piece of
carpet and slowly run it over the newly laid paving. The plate should
not come into direct contact with the pavers. As the compactor vibrates,
more jointing sand will fall between the joints. Finally sweep away
the rest of the white sand.
