What is VersiJack®

VersiJack® is a heavy duty height and slope adjustable pedestal designed for floor, deck, paver, beam and bearer support.

VersiJack® is used in the construction of roof terraces, pedestrian walkways, roof gardens, plaza decks, sun decks, balconies, pool surrounds, podium landscapes and verandas.

VersiJack® screwjack pedestal is height-adjustable from 37 mm to 1014 mm, with the use of proprietary “extenders”. An integrated slope corrector adjusts for slopes up to 5%.

VersiJack® reduces sound transmission, increases heat insulation and allows unsightly services to be concealed within the cavity under the elevated platform allowing easy access when required.

VersiJack® is used to create raised floors with most pavers including granite, marble, porcelain and precast concrete. These adjustable pedestal decking are widely used to support timber and composite bearers, and excellent for creating reusable or temporary exhibition flooring.


VersiJack® screwjack adjustable pedestals function for flooring support, deck support, beam, bearer and paver support on:

  • Roof terraces
  • Pedestrians walkways
  • Roof gardens
  • Plaza decks
  • Balconies
  • Pool surrounds
  • Reflective pools
  • Podium landscapes
  • Under water features
  • Raised technical floors
  • Under Solar panels
  • Temporary floors or Exhibition stands
  • Eliminating the use of bedding sand
  • Easy access to concealed services and waterproofing membranes
  • Waterproofing membranes not penetrated
  • Allowing air ventilation and increased heat insulation
  • Elimination of efflorescence and algae
  • A cost effective alternative to brick piers
  • Stable deck support
  • Minimising sound transmission
  • Support US LEED™ credits
  • Measure the total area to be paved to determine the number of pavers or beams required. One VersiJack® screwjack pedestal is required for every paver or for approximately each linear metre of beam to be supported.
  • Use sight or laser lines to mark the intersections of the corners of each paver to be laid.
  • Adjust the 0–5% inclinator to compensate for any fall in the slab.
  • Use 1–2 mm VersiJack® rubber shims if required to ensure each paver is level.
  • Position VersiJack® screwjack pedestals without tabs where edges and corners are to be supported. If necessary, saw along marked score lines on the bottom of the units so that units may be positioned along wall edges or in corners.
  • Commence paving by positioning the first paver in a corner and subsequent pavers along a wall edge.
  • Place the pavers into place on each VersiJack® screwjack pedestal and simply adjust either up or down to ensure each paver is level.
  • Position VersiJack® screwjack pedestals under beams and adjust units either up or down. Screw the beam into the eyelet in the top of the VersiJack® or tie the beam to the screwjack unit to ensure stable floor support.
