Laying surface

The laying surface can be made from a stratified embedding with 99% compacted gravel and sand (old roads system), or from a 10/20 cm thick concrete casting.

This work must be carried out according to the best techniques according to the traffic, the climate and the conditions of the base ground.

The laying surface must be carried out in length and width in order to allow the flow of rainwater onto the finished floor (slope 1.5 cm per linear meter).

Laying the modules

Spread a layer of sand and cement mixed with “semi-dry” (max 150 kg of cement per m³ of sand) and level the mixture with a straightedge at a height of -7 cm below the finished surface; then lay the modules on the sand / concrete surface.

Once the modules have been installed, spread water and beat the modules with a vibrating machine, making cross passages along the joints of the modules and in general over the entire surface of the floor until perfect compacting and leveling.

Closing the joints

Make a very liquid mixture of fine sand and cement (1 part cement and 1 part sand) spread this mixture on the finished floor and allow it to fully enter the joints.

Go over and then remove the residues from the surface with the “raclette”. For a better quality of the joints, add acrylic products, such as Sikalattex, to the mixture.

Let it rest and then clean the floor with a low pressure jet of water, or with a machine equipped with a rotating sponge or a hand sponge.

Warnings

The finished floor can be used for the passage of cars or other means only after the joints are hard, 10/15 days depending on the ambient temperature.

Pedestrians can pass after 24/48 hours. With time, use and rain, the floor will improve its appearance, the natural colors of the stones will become more evident.
