The next step was to apply a layer around 20 cm thick of 0–35 mm road base material (recycled material may also be potentially employed), of which around the top 15 cm were stabilised with MAPESOIL 100 fibre-reinforced stabilising agent.
Once the ground had been shaped and then treated with MAPESOIL technology, a high-performance draining under-mat made from SBR and thermoplastic polymer binder with horizontal drainage was laid on the surface and, to complete the work, artificial turf of the latest generation with high-performance, ennobled elastomeric rubber infill was laid.
This means that water now flows away just below the playing surface, that is, through the pervious under-mat, and is carried down the slope of the crown to concrete channels installed along the long sides of the pitch.
What makes the stratigraphic layout used for this type of pitch so innovative is that there was no need to excavate more than 3,500 m3 of soil from an area of new land and there was no need to add a large amount of raw aggregates or install a network of drainage pipes. An important factor to consider is that, if a traditional solution with vertical drainage had been adopted, it would have required more than 400 truck journeys going through the nearby city of Sassuolo to dispose of the topsoil and to bring freshly-excavated material from quarries to make the drainage layers.
MAPESOIL technology, on the other hand, in combination with the geomesh positioned at the bottom of the structure of the pitch, helped to greatly reduce the amount of excavation work and the amount of aggregates that would have been required, while at the same time increased the load-bearing capacity of the area where the intervention took place and improved the functionality of the playing surface.
Technological innovation at the service of the city of Sassuolo: the inhabitants of the city weren’t even aware of the building site… for which they are truly grateful!
