Concrete grass grid REDES

A vibro-moulded, reinforced concrete cast stone grid paving system that acts as a semi-vegetative blanket on a horizontal or sloped surface. The square geometry of each piece of Redes is in the form of a mesh that contains three concrete platforms connected to each other by concrete ribs hidden beneath the vegetation. Their cross section permits the optimum development and growth of the grass which colonises the empty spaces in different Grassing proportions. Due to its high drainage capacity, it maintains the natural rainwater cycle, re-injecting it into the water table. Redes can also be adapted to gently undulating reliefs.It combines 50% hard surface vs. 50% grass surface, ensuring stable footing in all directions. The Solar Reflectance Index by UV, visible and near infrared spectrophotometry pursuant to the ASTM E903 standard, obtains a result of SRI=38.2%. The Grassing permeability coefficient is 50% according to measurements contrasted in test laboratories. Vibro-moulded reinforced concrete paving stones in a 60x60 cm format and with a thickness of 10 cm, with a moulded finish and a fine smooth texture in colur grey. The slabs are placed on a compacted sand bed with a thickness of 4-6 cm, which in turn is spread over a bed of levelled P.M 95% compacted soil (UNE 103-501-94). It is then filled with topsoil before sowing, or just with sand. Suitable for both pedestrian and light to medium vehicular traffic.
