Pervious Paving Options

Benefits of pervious surface.

Pervious paving options.

The ins and outs of permeable pavement. Permeable paving materials can accomplish much more than save you money on a new driveway. This is an approved stormwaterwise landscapes program practice. Alternatives to traditional pavement on our paved surfaces can help reduce runoff by infiltrating rain water and melting snow.

Unlike traditional impervious paving materials permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate. With recycled rubber porous pave offers superior permeability exceptional versatility and demonstrated durability. Pervious concrete which has little to no sand in its mix allows water to run through its porous surface eliminating the run off issues commonly associated with asphalt and concrete driveways. Permeable surfaces also cut the amount of rainwater that falls off roofs runs down hard impermeable driveways and fills rivers ponds and municipal water systems.

However they are all sustainable and allow water to flow through their surface. With the use of admixtures today s pervious concrete mixes can be made with less water which improves strength and. Pervious surfaces can be used for driveways walkways and patios and are as functional as traditional materials asphalt and concrete. Pervious surface options include paver stones pervious concrete interlocking grids with gravel and pervious asphalt.

It s possible to achieve pervious concrete compressive strengths of 3000 to 4000 psi and flexural strengths of 500 to 600 psi which are on par with conventional concrete. A pervious concrete mixture contains little or no sand creating a substantial void content. Porous pave is a pour in place permeable paving material that is highly porous flexible and resilient. While other non porous materials direct water to storm drains these surfaces help ground water recharge by allowing water to flow into open spaces between the materials.

Permeable paving is a method of paving vehicle and pedestrian pathways to enable infiltration of stormwater runoff permeable pavement surfaces typically include pervious concrete porous asphalt paving stones and interlocking pavers. These alternative materials which include pervious asphalt pervious concrete interlocking pavers and plastic grid pavers allow rain and snowmelt to seep through the surface down to underlying layers of soil and gravel. Permeable paving is categorized using many different building materials. Permeable concrete consists of cement a coarse aggregate and water with little to no fine aggregates sand or clay.

The american society for testing and materials astm has a set of standards for both pervious and non pervious. That is why permeable concrete has a very rough and uneven appearance.
