Porous Paving

STF is a proven alternative porous paving system to asphalt and conventional concrete. This unique "poured-in-place" concrete is porous, allowing rainwater to pass through at a rate which completely eliminates surface ponding and addresses "first flush" issues.

Planners and "other decision makers" can apply the STF Porous Paving System as a —

  • cost-effective and innovative approach to pollution prevention
  • energy saving system
  • helping to create a more pleasant urban environment and
  • zero run-offs
  • STF Porous Paving System can save the site owner added costs, and Storm water issues can be addressed much earlier in the development process.

    Because of the porous paving system, no tie-ins to municipal storm water systems are required, and no grassy swales or other land-wasting pollution mitigation measures are necessary.

    Engineers working with this system have realized that this is the best way to construct a parking lot without interfering with the local hydrology. Usage of conventional drains and manholes are drastically reduced. And by replacing impervious parking lots, driveways and pavements much of the drought stress currently suffered by urban trees can be eliminated.

    STF Porous Paving System reduces heat island and site runoff provideint the ultimate environmental and low cost solution.

    Overall, on typical projects, STF can realistically contribute up to nine LEED credits. SS cr6 (2), SS cr7 (1), MR cr2 (2) MR cr4(2), MRcr5 (2).

    T.B. Penick has installed hundreds of thousands of square feet of STF in San Diego, including UCSD, Cottonwood Creek Park and at the Ranch House at Del Sur.

    Pervious Concrete Elements™

    Patent No. 8,312,690
    Pervious Concrete is a proven alternative to conventional impermeable pavements. With 15-25% void space, rainwater passes through at a rate that completely eliminates surface ponding and a vast area to catch oil and chemical pollutants. Use of pervious concrete reduces the need for large detention ponds.
     
    Pervious Concrete Elements™ improves pervious concrete by solving its aesthetic deficiencies and providing a smoother walking surface. Pervious Concrete Elements™ opens the door to an unlimited range of colors in glass, aggregates, and integral color. Utilizing smaller aggregates in the top surface creates a tight yet permeable decorative layer. Our two part monolithic two-part installation methodology enables us to install the system cost effectively.
