In addition to maintaining water quality and preventing the introduction of contaminants, Interlocking Pavers can help with a variety of storm-water runoff and groundwater problems on driveways and walks. They contribute to environmental preservation by enabling water to sink into the ground and be filtered there before entering our water supply. Permeable pavements also aid in lowering soil runoff and erosion. Because they are now required in many areas for these particular reasons, the use of permeable interlocking concrete pavers or permeable pavement is rising considerably. Many businesses employ them to earn better LEED certifications and the corresponding tax advantages.
