Instar: Adjustable Paving & Decking Supports

Adustable Paving Supports
Adjustable Decking Supports

InStar adjustable plastic paving & decking supports enable the paving slabs to be lifted off the roof surface thereby allowing for effective drainage between and beneath. Fine height adjustment is achieved by rotation of the head.


The four lugs at the head of the support ensure uniform alignment and spacing of the paving slabs.


The “screw type” adjustment allows for fine height adjustment to accommodate roof slopes and irregularities in the roof surface.


With heights ranging from 25mm up to 270mm, paved deck areas can be laid flat even when substantial slopes have been incorporated in the underlying substrate.

With the potential of large cavities beneath the slab, pipes and cables can be stored beneath.

The supports comprise of three parts: a base, a threaded height control middle section and a rubber surfaced head piece. 




Installation of the paving is made simple by placement of the paving supports at each corner of each slab. The alignment lugs will ensure accurate spacing between slabs.
It is essential to ensure that the first row of slabs are laid carefully in line as these will act as a guide for each subsequent row. The paving supports will be held firmly in place by the weight of the preceding slab enabling quick and accurate placing of the next row.
