The PAVE-EL pedestal system elevates levels and uniformly spaces paver stones and protects the substrates in such waterproofed installations as roof decks and promenades, terraces, balconies, patios, podiums, plazas, arenas and roof gardens. It is also ideal for roof garden walkways, for use as support pedestals or sleepers for catwalks, mechanical access walkways, balcony-deck structures and roof-mounted duct pipes.

          ** NOTE TO SPECIFIER ** The PAVE-EL system is not recommended for vehicular traffic applications. PAVE-EL system was designed specifically for use with square or rectangular pavers. Consult with Envirospec Inc. for use with other shapes.
          A.Pedestrian Traffic Applications: The pedestal size selected to support the scheduled paver as intended shall comply with the following.
          ** NOTE TO SPECIFIER ** Delete paver size not required. 18 inches by 18 inches (457 mm by 457 mm) is the smallest paver size recommended by pedestal manufacturer.
          1.Paver Size: 18 inches by 18 inches (457 mm by 457 mm).
          2.Paver Size: 24 inches by 24 inches (610 mm by 610 mm).

          10.Live Load: 200 psf (9.58 kPa).
          ** NOTE TO SPECIFIER ** Consult with membrane manufacturer, insulation manufacturer and Envirospec Inc. if uncertain about compatibility of loading between membrane and pedestal.
          11.Minimum Compressive Force of Pedestal Substrate: 30 psf.
          A.Do not begin installation until substrates have been properly prepared.
          B.If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
          A.Clean surfaces thoroughly prior to installation.
          B.Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
          ** NOTE TO SPECIFIER ** Bituminous waterproofing membranes are subject to softening at high ambient temperatures. It is recommended that protection board or topping be used under the pedestal to decrease point load pressure on the membrane.
          1.Confirm pedestal size selected does not exceed compressive strength of pedestal supporting substrate.
          ** NOTE TO SPECIFIER ** Pedestal Requirements: Use basically the same number of pedestals as pavers on square or rectangular decks. Columns and other protrusions, where pavers are cut and fit, will increase number of pedestals required.
** NOTE TO SPECIFIER ** Leveling Plate Requirements: For general shimming adjustments, approximately 10 leveling plates per 100 pedestals are required. Irregular deck surfaces or pavers of varying thickness will increase number required.
          A.Install in accordance with manufacturer's instructions.
          ** NOTE TO SPECIFIER ** Delete if not required.
          B.Horizontal Leveling.
          1.On deck areas where a dead level paver surface is required, full shimming with leveling plates and multiple stacking of pedestals shall be utilized.
          ** NOTE TO SPECIFIER ** Delete if not required.
          1.On deck perimeter and around protrusions where it is not practical to cut pavers to fit (i.e. canted roof-wall junctures), coarse gravel with binder (if required) shall be used in voids.
          2.Following predetermined layout, locate first row of paver stones at an exterior edge of deck, using 1/2 pedestals at edges and 1/4 pedestals at corners and at partial angled paver locations.
          3.Place pedestals with projecting ribs facing upwards to ensure uniform paver stone joint spacing. Place pavers tight to spacer ribs to ensure even spacing.
          4.Place paver stones by lowering horizontally rather than nosing into position to eliminate possible indentation of substrate.
          5.Align and shim as required as work progresses. Vertical difference between pavers for walking surfaces shall not exceed 1/8 inch (3 mm).
          6.Run subsequent rows of pavers parallel to first row.
          7.Where multiple stacking of pedestals is employed, locate leveling plates on top of upper pedestal, never in-between or below pedestals.
          A.Protect installed products until completion of project.
          B.Touch-up, repair or replace damaged products before Substantial Completion.
