Perimeter Pedestal - AWS™
The AWS™ Pedestal System brings the answer to difficult edging dilemmas with our Perimeter Pedestal™. The DHS™ Pedestal and the Perimeter Pedestal™ are sustainably designed and constructed of fully recyclable, durable ABS and PVC plastics. The Perimeter Pedestal™ uses a top cap and base cap, secured with Schedule 40, 1-1/2" PVC to effectuate its elevation. Compression testing to 24" at 13,000 PSI.
General Description: The AWS Perimeter Pedestal™ is designed for use with Architectural Pavers, natural cut stone gauged for pedestal set and side sawn, wood tile systems and ceramic tiles designed for raised installations. Consisting of “snap fit” pedestal caps, and shims, made of rigid ABS plastic to form a cut to height pedestal system. The pedestal system is combined with “off the shelf” 1.5” diameter, SDR 40, PVC pipe cut to nominal lengths at installation.
Basic Use: The combination of top and base cap, shims and cut PVC pipe create a level surface. The top cap and bottom cap total 1⁄4” of your desired pedestal height. Buffer pads can be used to add a layer of protection for the membrane system. Top shims fit on either side of the top cap, used to fine tune leveling of pavers at an intersection.

Pre-installation;
-
Arrive at job site. Lead Foreman and job lead review the project layout.
-
Crew begins by sweeping the job site of debris.
-
Foreman instructs crew to off load the pavers and provides them with how many pavers are to be stocked on each installation area/deck.
-
Foreman and Lead measure from left to right making sure no small cuts end up at railings/walls.
-
Set string line going from north to south and east to west. The string line is a guide to maintain square sets of your pavers at the appropriate height. Most clients or architects would like to see the pavers tuck just underneath the threshold with cut pavers ending up against the side of the building/house
Installation;
-
Working in a four (4) person crew, three (3) crew members are setting pedestals and laying pavers.
-
One (1) crew person is cutting PVC pipe with a chop saw and snapping a top cap and a bottom cap on each piece before handing to the install crew.
-
At each row of the installation the install crew will call out measurements to the crew member running the chop saw minus 1/8” for a top cap (thread fully engaged), 1/4” for each of the bottom caps, and 1/8” for a buffer pad/slope compensator, totaling ¾”. It is safe to cut your PVC approximately one inch shy of your desired pedestal height and let the components make up the difference.
-
Installers have a small caddy tray with AWS top shims; slope compensators and buffer pads to fine tune the pedestal height and ensure a level installation. Other tools may include a tape measure, marking pencil, 4’ or 6’ level.
-
Begin by installing all the full sized pavers first. These are called the field pavers.
-
A normal installation will require one each of both sizes of top shims for every pedestal. Each top shim is designed to snap in to the two piece adjustable top cap.
-
Assign one (1) of the install crew to begin measuring, marking and cutting pavers for the areas that will require less than full pavers. The pavers are always to be cut using a wet saw with a diamond tip blade.
-
The best setup for using a wet saw is a pop-up canopy with snap on sidewall panels. To avoid potential staining and damage to property always set up the wet saw downwind from the building and downgrade.
-
Expect an experienced crew to set 150 pavers each per day (24x24, 18x18, 16x16).
-
An experienced crew can mark, cut and lay 120 lineal feet of paver per day.
AWS Pedestal Installation Helpful Hints
-
Do you have less than a two-inch clearance at a threshold? Start that row out using either a DHS Fixt head on a buffer pad (1” profile) or if even less is needed you can start that row with a Top Spacer on the buffer pad/slope compensator (1/4” profile).
-
When setting a pedestal against the wall/perimeter of the building/house you will want to be able to set your pedestal far enough under the two pavers at that intersection as to hide it from view. The DHS top caps and Top Spacer have four (4) fins designed to maintain consistent spacing of your pavers at every intersection. Use a utility hammer to knock off two (2) fins allowing the pedestal to slide along the seam between the pavers while still providing the support needed at that point. The top shims and the buffer pad function the same as always in this set. –OR- Build your perimeter pedestal using the perimeter top cap and base cap. Use top shims and ½ buffer pad (if desired) same as if making a standard pedestal. Place the perimeter pedestal as close to the containment as possible for a solid support. The single spacer fin provides the same 1/8” seem as regular DHS and Fixt head top caps. Perimeter pedestals are stronger than regular sets.
Clients and ordering;
-
Pedestal orders are normally calculated with up to a 5% override. This gives the installer enough parts to cover for unexpected corners, planter boxes that never show up on the drawing, bump outs that are created by framers who needed a little room for a drain chase and so on. On a 1000 pedestal installation you should be selling up to 1050 pedestals to cover the project. Overnight shipping and lost installation time is much more costly in the long run.
-
Roofing companies are some of the best clients. Landscapers and deck builders are becoming a larger segment for us.
*Always consult an engineer to determine load limits for your projects.
