Get PricePervious pavement is designed to let water naturally seep through it and go down into the soil beneath. Impervious pavement does not allow water to seep through it. Instead, with impervious pavement, water runs off into storm drains that are lined along the road or
Get Price2017-1-25 Permeable pavement is a pavement type with a porous surface that is composed of concrete, open pore pavers or asphalt with an underlying stone reservoir. Also considered as green pavement, it allows water to run through it rather than accumulate on it or run off of it. The precipitation and water get stored in the reservoir from where it slowly infiltrates the soil below or is drained via a ...

Get PricePervious concrete is very similar to porous asphalt. Pervious concrete is thought to be more affordable slightly than permeable pavers discussed below, yet is more expensive than porous asphalt discussed above. Pervious materials are more susceptible to freeze-thaw damage than porous materials, yet can retain more water than porous asphalt.
