AWS™ Pedestal System
AWS Joist Plate System AWS Calculations
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 applied directly over 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 11,000 lbs PSI from heights of 2" up to 20", when used with standard SDR35, 4" PVC pipe (conforming to ASTM 3034, 4.215" OD) as the central component.
The Joist Plate™ is a sister interlocking system. There are 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.
