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.amountofrainwater,runoffwaterfromhillsanddownspouts,soiltype,theinltrationrateofthepavers).
Apermeablebaseistypicallycomprisedofmultiplelayersofdifferentsizedfractured-facestones.Thebasematerialshould
beanopen-gradedaggregate,freefromsandsandothersmallparticles.Pleaserefertolocalrequirementsandspecica-
tions,orvisitICPI.orgformoreinformation.HereisagenericpermeablebasefoundontheICPIwebsite.
Thebasematerialneedstobecompactedevery2”asitisspreadout.Thiswillreduceanychanceofthebasematerialset-
tling over time making the installation uneven. Additional resources for base design can be found at www.icpi.org
Slope:

orfoundations.Thetypicalslopeisapproximately1inchover6feet.
Bedding Layer:
Thetoplayeriscomprisedof11/2”to2”ofa3/8“clean,fractured-facerock.Thiswillcreateaworkableandpermeable
surface for the pavers to install upon.

TAMPING PAVERS AND JOINT SAND
Thenalstepstonishuptheinstallationareacombinationoftampingandsandingthepavers.Thiswillevenoutsmall
undulations and lock the pavers into place.
Tamp (Compact) Pavers:
Priortosandingthepavers,useavibratoryplatecompactororahandtampertoworkthepaversintothesandbed.This
willtypicallycausethepaverstosinkapproximately1/4”intothebeddingsandandwillreducesmallundulations.
•Avibratoryplatecompactorwilltakeonetotwopassesinbothdirections.
•Ahandtamperwillrequireseveralstrikesineachlocation.
oMovearoundasyoustrikethepaversandmakeseveralpasses.
•Thehighundulatedareascanbefurthertampedtoeventhesurface.
IMPORTANT:Reviewthesurfaceaftertampingforanyimperfections.Ifanyarefound,liftupthepaversandgridandeither
add or remove sand to make it level. Re-tamp the pavers after the imperfections have been removed.
Sweep in Joint Sand and Tamp Pavers:
Thesamesandusedforthesandbedcanbeusedforthejointll.Thisisaclean,sharpandwell-gradedcoarsesand.Donot
useoverlynesands;coarsesandwillperformbetter.ThestandardspecicationforjointsandisASTMC33.
•Startbyspreadingthesandacrossthepaverswithashovel.
•Allowthesandtodrycompletely;thiswillmakeiteasiertogetintothejoints.
•Useabroomtospreadthesandacrossthejoints,sweepinginalldirections.
•Continuetospreadandsweepthesandwhiletampingthepavers.
o This can be done with a hand tamper or plate compactor.
•Whenthejointsappeartobelledtothedesiredlevel,sweeptheinstallationcleanofanyremainingsandordust.
•Thepaverswillreturntotheiroriginalcoloroncethepavershavebeencleanedbyrain.
•Additionaljointsandapplicationsmaybenecessaryafterrainorsettlingofthejointsandoccurs.
IMPORTANT: DonotusepolymericsandwiththeAZEKPaversystem.Asthesystemexpandsandcontractsitmaycausethe
polymericsandstobreakawayfromtheedgesofthepavers.

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,andperimeterpaversfromtippingoffthegrid.Theedgingisgenerallystakeddownusing10inchstakes,oneevery6
to 12 inches. Plastic, aluminum, or concrete edging will work.
Edgerestraintscanbeinstallednextto,orontopof,AZEKInstallationGrids.Forareasthatwilleventuallybeborderedby
sod,orthathaveacurvedperimeter,someinstallersmayprefertoinstalledgingoverthetopoftheinstallationgrids.Ifthis
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.
Ifabutteddirectlytoasphalt,expansionoftheAZEKPaversystemmaypushtheasphaltandcauseittobuckle.
