The AWS™ Pedestal System is an interlocking pedestal support used to level pavers and other natural products appropriate for elevated foot traffic as applied to a pitched deck or roofing membrane. It turns difficult slopes into level surfaces and allows utilities and drains to be run under the pavers, natural stone, or other manufactured products, transforming to usable spaces those which might otherwise not be. Water can move freely to allow for the health and long life of a roofing membrane.

Units of the AWS™ Pedestal System with a smooth, flanged, bottom cap can be used applied directly to a roofing membrane using the bottom cap with or without a bottom shim (1/16” or 1/8”). All pieces of the AWS™ Pedestal System are ABS and benignly designed to be membrane friendly.

The AWS™ Pedestal System has been compression tested to withstand loads of 14,250 lbs PSI (at 2”), 13,650 lbs PSI (at 6”), and 12,550 lbs PSI (at 15”) when used with an SDR35, Schedule 3034 PVC pipe central component 4" OD.

The AWS™ Pedestal System is compatible with applications of built up waterproof membrane, and single ply membranes, rubberized asphalt (with protection or insulation board as a barrier), also the new PVC “breathable” membrane. Bituminous waterproofing membranes are subject to softening at high temperatures, and a protection board or AWS™ Pedestal System's "Buffer Pad" (1/16" x 7" diameter) is here recommended.

The Joist Plate™ is a sister interlocking system, using a new component (Joist Plate™) and the top and bottom shims from AWS™ Pedestal System for leveling and spacing natural products and hydro-pressed slabs (usually 16x16 or 18x18) over wood joists. This system, as applied to your new or old deck, virtually ends the drudgery of maintaining a wood slat deck. 4x6's should be used in new construction, or sistering 2x4's with 2x4's should provide a working underlayment. If your deck is suspended, engineering may be required to support the weight of concrete pavers or other gauged natural products. Consult a specialist regarding load and structural requirements.

The Buffer Pads is 1/8" thick X 7" diameter rubber, for added protection on softer, more sensitive roofing membranes - locks with top cap, bottom cap, or bottom shim.

Formula for Calculating Pedestals

Example No.1		Example No. 2
Materials used: 24” x 24” HydraPressed Slabs (4 SF per paver)		Materials Used: 18” x 18” HydraPressed Slabs (2.25 SF per paver)
Square Feet Coverage: 1000 SF (20’ x 50’)		Square Feet Coverage: 800 SF (20’ x 40’)
Formulas: 1,000 SF / 4 SF = 250 Pavers & 250 AWS needed		Formulas: 800 SF / 2.25 SF = 355 Pavers & 355 AWS needed
Calculation of Perimeter (Lineal feet) 20’ x 50’ area = 140 lineal foot perimeter 140’ x 12” = 1,680” 1,680” / 24” (length of paver) = 70 pedestals		*Calculation of Perimeter (Lineal feet)* 20’ x 40’ area = 120 lineal foot perimeter 120’ x 12” = 1,440” 1,440” / 18 (length of paver) = 80 pedestals
Total: 250 + 70 = 320 pedestals needed		Total: 355 + 80 = 435 pedestals needed

Calculation of perimeter should include inner spaces such as planters
