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.
