Frequently asked questions

What is permeable pavement?

Permeable paver systems are permeable pavers, pervious concrete, or porous asphalt. All three systems enhance groundwater infiltration, limit water runoff, filter out groundwater pollutants, and use a stone aggregate base below as a reservoir before the water seeps into the soil or city drains.

  • Pervious concrete and porous asphalt are regular pavements without fine-grain materials like sand, so they become porous. Water goes down through the surface.
  • Permeable pavers are brick or concrete pavement stones with gravel-filled spaces in between for water infiltration into gravel layers below. Permeable pavers have a lower drainage rate than porous or pervious systems. Also known as “permeable interlocking concrete pavements” (PICP).

What is the lifespan of permeable pavement?

Most types of permeable pavement last 20 to 40 years on average, depending on the pavement materials, installation quality, and maintenance frequency.

Permeable pavement lifespan
Pavement type Average lifespan (years)
Permeable interlocking pavers 20 – 35
Pervious concrete 20 – 40
Porous asphalt 15 – 30
Concrete grid 10 – 20
Plastic grid 20 – 60

What's the difference between pervious, porous, and permeable pavers?

Pervious, porous, and permeable pavers are different paving systems that reduce stormwater runoff. Each paver type has a different installation process and application, depending on the soil and site conditions. Pervious concrete drains faster than porous asphalt or permeable pavers.

Pervious, porous, and permeable paver differences
Paver type Features
Permeable stone paver system
  • Most common type
  • Gravel-filled joints drain water between paver stones
  • Concrete or clay brick pavers
  • Architectural appearance
  • Good for heavy traffic
  • Lowest infiltration rate
Porous pavers (grass- or gravel-grid pavers)
  • Water drains through a cellular grid system
  • Concrete or plastic honeycomb design
  • Grids filled with dirt, gravel, sand, or grass
  • Vegetation grows through open cells
  • Reduces soil compaction
Pervious pavers
  • Drains through open voids in the stone’s surface
  • Highest infiltration rate of all systems
  • Made from natural stone
  • Bonded with organic compounds & UV inhibitors
  • Allows tree roots and microbes to interact

Do permeable pavers only work for driveways?

Permeable pavers are installed in various locations such as driveways, sidewalks, garden paths, patios, parking lots, pool decks, and other backyard landscaping projects.

Where to use permeable pavers:

  • Use permeable pavers around garden boundaries to supply more groundwater to plants.
  • Avoid plastic and only use stone-based permeable pavers near backyard grills and firepits.
  • Avoid using permeable pavers near a home foundation. Permeable paving traps water in the ground below instead of channeling water away to keep the foundation dry.

How much does Topmix Permeable concrete cost?

Topmix Permeable concrete or similar types cost $8 to $16 per square foot installed. Topmix is a patented concrete blend from Tarmac, a United Kingdom company, currently unavailable in the United States. Other pervious concretes are available from U.S. suppliers like Cemex in this price range.

How much does Ecoraster® cost?

Hiring a permeable pavement installer

Before hiring an installer, make sure to:

  • Collect estimates from three paving companies to compare prices.
  • Browse reviews from their previous work on HomeGuide, Google, and the Better Business Bureau(BBB).
  • Choose companies with experience installing permeable paving.
  • Pervious-concrete installers should have pervious-concrete certification from the National Ready Mixed Concrete Association.
  • Grid-system installers should have taken installation courses from the grid manufacturer or other LEED construction courses.
  • Porous-asphalt installers should have certification from asphalt-training programs like the State Department of Transportation.
  • Landscapers installing permeable paving-stone systems should have a current general contractor’s license and certification from the Interlocking Concrete Pavement Institute.
  • Beware of ultra-low bids for low-quality work.
  • Select only insured, bonded, and licensed contractors.
  • Never make full upfront payments. Follow a payment schedule instead.
  • Ask for a written copy of the detailed estimate, contract, and warranty beforehand.
