Before the process of laying paving slabs, it is necessary, first of all, to prepare the base. A gravel-sand pillow can be the basis, as an alternative, you can choose the installation of a concrete base. The covered surface must be prepared by aging levels, as well as the device for slopes for drainage. After all the calculations were made, you can proceed to trace, otherwise the markup, using pegs and twine. After accurate tracing is carried out, you can remove the soil from the designated site. When laying tiles, the possibility of laying communications should be taken into account. In order to get a high -quality base, it is necessary to use crushed stone or gravel.
A layer of material used for the base should not be less than 10-15 cm for those surfaces that are designed for pedestrians, or 15-20 cm in parking lots. The tamped base must be covered using geosynthetic material, this should be done in order to separate the sand and crushed stone from waking up. A layer of sand should be in the range from 40 to 50 mm, after the laying process, the sand should be well compacted. Mandatory should be checked for evenness, while the construction level is used.
In the case when the sand is laid on the weak soil, it is recommended to lay out geotextiles in 2 layers, the first is laid until the crushed stone is laid, the second is after. This is how the bearing capacity inherent in the foundation increases.
