Permeable Interlocking Concrete Pavers
1. Biomimicry and
Permeable Interlocking
Concrete Pavements (“PICP”)
…a ‘natural’ approach

2. Permeable Interlocking Concrete Pavement
An innovative, sustainable
pavement that functions both
as a durable traffic surface
and
a stormwater infiltration or
detention system
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. 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. PICP Components
• “Permeable” Pavers
– Manufactured to the same specification as
“standard” pavers
– But, includes “drainage features”
• Wide joints
• Drainage holes

“….development that meets the needs of
the present without compromising the
ability of future generations to meet
their own needs.”
(1987 UN World Commission on Environment and Development)
