Permeable Interlocking Concrete Pavers

  1. 1. Biomimicry and Permeable Interlocking Concrete Pavements (“PICP”) …a ‘natural’ approach Rick Crooks Mutual Materials Company www.mutualmaterials.com Summer Teachers Institute: June 24, 2015 Thurston Conservation District
  2. 2. Permeable Interlocking Concrete Pavement An innovative, sustainable pavement that functions both as a durable traffic surface and a stormwater infiltration or detention system
  3. 3. Permeable Interlocking Concrete Pavement (“PICP”)
  4. 4. Permeable Interlocking Concrete Pavements Differ from standard interlocking concrete pavements: •  They have the same material characteristics (high strength, durable finish), but… •  The system of underlying base aggregates and paver drainage features allow for infiltration of stormwater runoff… •  This decreases negative impacts on our environment and lets our paved surfaces act as a stormwater infiltration or detention system
  5. 5. PICP System Benefits •  Increased groundwater recharge •  Contaminants are filtered and reduced •  Peak flows and volumes are lowered, reducing downstream flow and erosion •  Runoff temperatures are lowered •  Visually attractive pavement •  Ability to reinstate after repairs •  Maintainable - clogged openings can be cleaned •  Immediately serviceable
  6. 6. PICP Components •  “Permeable” Pavers – Manufactured to the same specification as “standard” pavers – But, includes “drainage features” •  Wide joints •  Drainage holes
  7. 7. Eco-Stone ® paver
  8. 8. Ecoloc® Paver
  9. 9. Eco-Priora ® 4 x 8 8 x 8
  10. 10. Eco-Priora®
  11. 11. PICP Components •  Free-draining aggregates – “Clean, crushed rock” aggregates: •  Jointing material and bedding course –  “ASTM No. 8” aggregate, (1/4” to 3/8”) •  Base material –  “ASTM No. 57 “ aggregate, (3/4” to 1-1/4”) •  Subbase material –  “ASTM No. 2 “ aggregate, (2” to 3”)
  12. 12. PICP Design Design and construct according to industry guidelines
