SikaRoof® VersiJack®

HEIGHT-ADJUSTABLE PEDESTAL SYSTEM FOR RAISED PAVERS AND DECKING FLOORING

SikaRoof® VersiJack® is an adjustable pedestal designed to support and level pavers and decking in raised flooring applications. Pedestals are manufactured from recycled polypropylene (PP), while fire-rated pedestals are manufactured from modified reinforced thermoplastics, and it uses a stepjack or screwjack mechanism to provide precise millimetric adjustments from 13 mm to 281 mm, and has a locking ring to secure the pedestal height. Creating a raised flooring generates usable space through hiding M&E services, and the void area also provides an insulation layer. Raised floorings also improves surface drainage, while providing waterproofing protection, waterproofing maintenance access and efflorescence elimination.

  • Conceal M&E services

Application

Application steps

SUBSTRATE PREPARATION

Clean and sound surface shall have at least a wood float finish. All holes, joints, and cracks and honeycombs in concrete or masonry surfaces shall be filled with an approved grout and allowed to cure. High spots in concrete or masonry surfaces shall be cut off or ground down to prevent damage/puncture to the pedestal base.

APPLICATION

SikaRoof® VersiJack® shall be loosely laid without any mechanical fixing either on top of the waterproofing membrane or on top of the concrete surface. For a bonded application, the pedestal may be adhered to the substrate with an approved adhesive. The first paver shall be installed to the correct elevation before using a levelling device to serve as a reference. Subsequent pavers shall be installed and checked to ensure consistent and correct elevation, till a sturdy and rigid raised flooring is obtained, free of rattling, squeaking or other noises.
