The usage of this technology provides a voidage ratio greater than 95%, requiring excavation volumes three times smaller than those of traditional gravel systems. The low density of the modules and the reduction in excavation volumes moreover assure a particularly simple and rapid installation: all advantages which when summed with those of its complete modularity and the possibility of cutting-to-size, do make Refill-Tech Solutions’ products adaptable to a great diversity of morphological requirements as well as to the most particular and demanding project requirements, by no means least of which the ability to guarantee the carriageability of the areas above the drainage plant.
ADVANTAGES
Logistical: it requires an excavation volume three times smaller than that required by traditional gravel drainage systems
Operative: the lightweight modules can be installed without the assistance of mechanical handlingequipment
Time-saving: the lightness of the modules means that they can be moved and installed very rapidly
Technical-Hydraulic: this fill assures a regular and even distribution of the water, allowing the tank to be able to face the peak rainfall events
Mechanical: the high mechanical strength permits the carriageability/load-bearing of the drainage system and the recovery and usage of the areas above it
Environmental Sustainability: Use of regenerated PVC and reduction in transport volume correspond to a reduced CO2 footprintan
