The site illustrates the creation of beds in grit resin with a fountain designed by us for the Rotary Club of Guidonia Montecelio (RM). The mixed resin (mm.9/12) with the grit type 3 (mm.9/12) in a quantity of 1.5 liters for 3 bags of 25 kg, produces an area of at least 3 cm of surface mq.1,5 perfectly fixed. The layer is made permeable to water and does not allow the growth of grass. With this type of realization is possible to build footpaths, water permeable and therefore environmentally friendly. This technology is also very useful for public offices to reduce the costs of maintenance of the flower beds and the growing number of roundabouts.
