VS 5™ ECO
Rapid urbanization has posed new challenges on all of us. We build more houses, plazas, commercial buildings and roads. All these surfaces are impervious and generate additional runoff during rainstorms. These runoffs carry pollutants and sediments that enter water sources. They erode streams, degenerate environments and pollute drinking water.
U.S. federal law mandates that states control water pollution in runoff through the National Pollutant Discharge Elimination System (NPDES). Environmental agencies in the United States and Canada also require to implement best management practices (BMPs) to control non-point source pollution in runoff. |
VS 5 – Eco, VS 5 – Drain and SF-Rima™ pavements are the solution to deal with stormwater runoff. They are very effective in providing infiltration at the spot, allowing rainwater to pass through joints between the stones, through aggregate layers for temporary storage, filtering, and treatment and eventually it is released to the ground water.
All SF permeable concrete pavements can reduce runoff of almost 100% from frequent, low intensity and short rainstorms. The long-term infiltration rate is estimated at 3.8 in./hr. for a 20-year life. It is recommended however, to provide drainage swales to handle flows that exceed the design rainstorm.

VS 5 - Eco pavements are eligible for LEED credits under the U.S. and Canadian Green Building Councils guidelines.
VS 5 – Eco is a permeable interlocking paving system with shift resistance on 5 sides of the stone. The geometrical configuration of profiles around VS 5 – Eco transfers vertical and horizontal loads to adjacent stones and improves resistance to lateral shifting. The joints provide sufficient space for water infiltration.

Grooves on the underside lock the VS 5 Eco pavers into the bedding and reduce horizontal shifting.
Applications: for residential roads, industrial yards, residential and commercial parking lots, driveways, walkways, plazas and more.
