Instar: TPO Paving & Decking Supports

9mm TPO Paving Support


InStar rubber paving supports offer a simple solution to the raising of prefabricated paving slabs off the roof surface to enable effective drainage between and beneath.


The four lugs on the upper side ensure uniform alignment and spacing of the paving slabs.


InStar rubber paving supports are made from high grade flexible synthetic rubber which is resistant to extremes of heat and cold and also offers good insulating properties against sound and vibration.


The 9mm thick moulded design incorporates grooves on the underside to provide good drainage and can be segmented into halves and quarters for use at corners and edges with the aid of a pair of tin snips or a small saw.

The paving slabs are loose laid on to the paving supports and held in place by the spacing lugs, as there is no cement mortar used in this method of laying, the slabs can be easily lifted if required in the future.


Any minor level differences in the substrate or lapped joints in the waterproofing can be accommodated by the use of 2mm plastic shims which fit neatly on top of the paving supports.

InStar rubber paving supports are packaged in strong recyclable woven polypropylene bags which, unlike cardboard packaging, will not be affected by wet site conditions.
