Why ECO: What are ECO Pavers?
EP Henry's Permeable Interlocking Paving Systems - ECO™ Bristol Stone, ECO Pavers and ECO Cobble® - are uniquely designed to be used as sustainable paving systems for both pedestrian and vehicular applications. Installing EP Henry's Permeable Interlocking Paving Systems on your client's commercial or residential patios, walkways, or driveways is a great way to reduce storm water run-off, adhere to Best Management Practices (BMP) by the EPA and state agencies, and obtain credits for your LEED-certified projects.
EP Henry's ECO Bristol Stone and ECO Cobble offers an unprecedented selection of sizes, colors, textures, patterns, and performance; and they can be interchangeably installed with our non-permeable Bristol Stone and Old Towne Cobble™ pavers-thus offering you limitless options to meet your design, budgetary, and environmental requirements.
How EP Henry ECO Pavers work
Infiltration: The penetration of water through the ground surface into the subsoil
Exfiltration: The loss of water from a drainage/permeable pavement system into the surrounding soil
Ideally, the quantity of water that enters a permeable paver system should infiltrate/exfiltrate your permeable paver system within 24 to 48 hours. However, it's possible that your underlying soils can't absorb water rapidly enough due to the composition of the soil. In cases where your soil can't absorb the water received in a given precipitation event within 24 to 48 hours, conveyance movement via drainage pipes to additional storage or infiltration areas may be appropriate.
In basic terms, clay can absorb the least amount of water, and sand can absorb the most. It is important to note that when using the Partial or No Exfiltration construction details, a drainage pipe is specified which must have positive flow away from the aggregate base. This drainage pipe can be directed to auxiliary on-site infiltration trenches, rain gardens, bio-swales, detention basins, or nearby storm pipes. Municipal approval is required for any stormwater "tie-ins."
