Why ECO: Installation of Permeable Pavers
This overview is intended to be a basic guide to permable paver installation and to explain the site conditions that dictate the specific methodology required for proper performance. EP Henry recommends you consult a Professional Engineer (PE) for permeable pavement installation.
Determining the onsite underlying soil type (clay, silt, sand)
is the first step in
Ideally, the quantity of water that enters a permeable paver
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
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
The following represent several common details for ECO Paver, ECO Cobble and ECO Bristol Stone:
Appropriate for soils having high clay content, those constructed over bedrock, a high water table, or environmental "hot spots"
Appropriate for soils of medium texture, with roughly equals
portions of sand, silt, and a little less clay
Appropriate for soils that are very sandy, with no clay, and very few fine particles
