General hints for laying according to standards

After the laying process is done it is necessary to move the new laid paving stones a little bit in direction of the
facing bedding sand (the best way for the operating personal is to use his feet). This is the only way to achieve a
standard joint (3 – 5 mm). If it is necessary to start with manual laying before you can use the installation clamp,
take care that the grid system of the paving layers is correct. Do not manipulate the joints with the rubber
hammer, because the result will be a non-standard paving area.

General laying-hints:

●
To optimize the high degree of mechanization in the mechanical paver laying it is necessary t optimize the
boundary conditions. Because the laying process consists in majority of transportation and the process of
paving is the smaller part it is evident to optimize the transportation on the building ground.
●
According to the paving configuration it could be necessary, to lay additional paving stones for the connection
with the already laid paving stones or to change the location of paving stones.
●
Place the paving packages near to the laying edge to avoid transportation and to have short driving distances
and a good laying performance. Provide enough space for the manoeuvrability of the laying machine.
●
It is the best to have a "just in time" delivery of the paving packages, so you can place the packages as near to
the laying edge as possible.
●
The distance of the packages on all sides must big enough to set the installation clamp on it.
●
Calculate the distance of the paving stone packages from the laying area and the square meter of the
packages, especially on narrow laying areas, e.g roads.
●
Place the packages on a plane surface and take care that they are not twisted.
●
Align the packages according to the optimum driving direction of the laying machine.
●
Some laying packages are asymmetric, take notice of a constant direction.
●
Some laying sequences, e.g. herring-bone, have cascades positions of the paving layers. Contact your paving
stone supplier for laying information and do not waste time with experiments.
●
If there is a separation between an old manual laying to the laying with the installation clamp it is the best to
make a new start, because the joints are different.
●
Check the orthogonality, the joint direction, the structural module. Adjustments at a later date could be
impossible or are very time expensive.
●
Avoid cutting and manual work by choosing a working width with a multiple width of the layer.
●
Mix the paving layers from different packages in the laying sequence.
●
Check the joint of course before compacting and filling with sand. Never compact nearer than approx. 30
meters to the open laying area.
●
Packaging material, e.g. pallets must be stacked immediately and the stack should be moved outside the
working area.
●
Provide a transportable container for waste such as plastic sheet and straps.
●
Cut the tightening straps on both sides, almost at the bottom of the package, to avoid accidental clipping of
the straps using the laying installation clamp. If this happens the running bond is moved and must be
corrected manually.
●
Provide a transportable tipping container for damaged paving stones and stone waste, to avoid an expensive
pick up later on and hindrance in the movement of the laying machine.
●
A clean and tidy building ground saves time and money.
●
If there are problems with the laying technique, there should be a direct phone contact between the personal
(driver of the laying machine) and the manufacturer of the laying machine. So the consultant of the
manufacturer is provided with all the information he needs to diagnose and help.
