10 1 3 5 2 4 6 Instead of the normal sedimentary dormant components referred to in the preceding paragraphs, it is sometimes possible and even suitable to improve the foundation’s water supply using inert volcanic material such as pumice sand and volcanic lapillo. The great advantage of these materials, which can be used in variable percentages, is that while they provide excellent drainage,they also guarantee high water retention (about 50% their volume). It is important to carry out an adequate evaluation of the local conditions of the soil. Our instructions are, in fact, in general terms and the preparation of the foundation must be suitable for the type of soil, the climatic conditions and the load intensity. PERMEABLE LAYER - Consisting of granular, fi nely crushed stone 3-10 mm. This layer, which obviously completes the division of loads, has the double function of draining excess meteoric water and simultaneously favouring root growth towards the lower layer. For this reason, thickness must amount to about 5/7 cm, and can be increased for rainy areas characterised by heavy soil with strong water retention. LAYING OF PRATOPRATICO® - The consecutive development of the modular surface will take place in a simple and rapid manner according to the modalities and patterns described in the paragraph “ASSEMBLY OF PRATOPRATICO®” Please refer to said paragraph for details. SOWING - Must be carried out immediately after laying the cultivable sublayer (3rd phase) in order to avoid excessive compactness. The seeds must be selected according to the nature of the site (pay attention to the altimetric quota) and the climate. In any case the grass seeds must be resistant to trampling. You are advised to use a blend composed of Lolium Perenne, Poa Pratensis,Festuca Arundinacea in the proportions and varieties suitable to each single case. Numerous packages with similar mixes, suitable for every need are easily found on sale. For excellent sowing, spread the seeds uniformly through passages crossing at right angles both manually and with the aid of mechanical means. SAND BED - This fi nishing layer, consisting of siliceous sand, about 3 cm thick, levels the surface on which PRATOPRATICO® modules are placed and favours root growth in the sub-layer contained in the grating below. FILLING OF THE PRATOPRATICO® CELLS - Placing of the cultivable sub-layer which will act as a base for the sowing components, composed of a mixture of siliceous sand, vegetable terrain, peat and inert volcanic material (pumice), enriched with slow-release fertilizer. The fi lling process must partially saturate the cells, the level reaching to 1cm below the fl ooring’s upper border. DELIMITING OF PARKING AREAS with the aid of signs Made in such a way so they can be inserted in any point of the fl ooring, they are available in the 3 classic colours provided by the Highway Code: (free parking areas), yellow (reserved parking spaces), for ex. parking spaces reserved for invalids. 2nd phase 1st phase 3rd phase About 5 cm of Pratopratico ® About 4 cm of soil About 3 cm of sand (optional) Permeable layer of about 5-7 cm.
