S F-Rima™ permeable concrete pavement is the solution to deal with stormwater runoff. It is very effective in providing infiltration at the spot, allowing rain water to pass through joints between the paving stones, through aggregate layers for temporary storage, filtering, treatment and eventually it is released to the ground water.

SF-Rima™ permeable concrete paving stone system is an effective solution of providing a structural pavement suitable for pedestrians and vehicular traffic while allowing rainwater to pass straight through the pavement construction for temporary storage and dispersal to the ground.

SF-Rima™ permeable concrete pavements can reduce runoff of almost 100% from frequent, low intensity and short rainstorms. The long-term infiltration rate is estimated at 3 in./hr for a 20-year life. It is recommended however, to provide drainage swales to handle flows that exceed the design rainstorm.
