What is SpiraPave®

SpiraPave® is a new generation, high strength pedestal consisting of separate paired components to create pedestals of different heights. Units may be adjusted either up or down in 1mm increments.

SpiraPave® is used to support bearers in the construction of roof terraces, pedestrian walkways, roof gardens, plaza decks, sun decks, pool surrounds and balconies.

SpiraPave® is adjustable in height from 20 to 87mm, making it ideal for installations where conventional supports are impractical.

SpiraPave® may be used in conjunction with a Slope Corrector which compensates for slopes of up to 5%.

SpiraPave® may be used with a Bearer Holder that caters for 50 to 85mm wide bearers.

SpiraPave® is lightweight, has a flat smooth base, and is easy to install. Unlike brick and metal piers, it does not damage water proofing membranes.
