Pratopratico grass and gravel paving grid

9 Laying for treadable surfaces with lawn fi nishing Any kind of intervention should be carried out after preparing a suitable design. The factors that are taken into consideration during this phase are: • The site of intervention under a geological, morphological and geotechnical profi le; • the use the product is destined for in terms of intensity and frequency of loading to which the fl ooring will be subjected (destined for pedestrians; light, medium, heavy traffi c; other); • the exposure and climatic conditons of the site. With reference to the nature of the site, it is important to have a supporting foundation that divides the concentrated loads by distributing them on the natural soil without causing sinking phenomena. Usually, this compact layer consisting of gravely sand and crushed stone of various granulometry, must be applied in relation to the use it is destined to and the quality of the soil. Refer to the diagram below for an example: In case of slopes it is important to consider the adherence coefficient. For this reason, assuming prudentially a wet surface and tires and medium/high use status, it is not recommended to use Pratopratico for inclinations greater than 8%. This slope can be incremented in case of gravel finishing. Intended use Substructure thickness in cm.
