PERMEABLE BASE MATERIAL
IMPORTANT: A civil engineer, landscape professional, or local municipality, is recommended to design the appropriate
permeable base. Each permeable application is different, and there are multiple considerations that must be taken into
account(e.g.amountofrainwater,runoffwaterfromhillsanddownspouts,soiltype,theinltrationrateofthepavers).

INSTALL EDGING
Edge Restraints:
AZEK Pavers require the use of an edge restraint around the perimeter. Edge restraints help keep the installation from mov-
ing,andperimeterpaversfromtippingoffthegrid.Theedgingisgenerallystakeddownusing10inchstakes,oneevery6
to 12 inches. Plastic, aluminum, or concrete edging will work.

is done, drill holes in the grid where the stakes will go.
IMPORTANT: When installed up against asphalt, a 4” wide ribbon of concrete the depth of the base material is recommended.
