The ultimate in structural strength, GRP sandwich panels are effectively made by bonding 4mm anti-slip flooring sheets to the top and bottom of a sheet of standard mesh grating. The added rigidity makes it the ideal solution for vehicular access and can be used to bridge trenches and gullies with confidence. Weighing considerably less than a steel or concrete equivalent, it costs far less to transport and install and is much longer-lasting.
It maintains all the inherent benefits of GRP including low-maintenance, corrosion-resistance and chemical-resistance and provides weather-proof protection for what lies beneath. If a truly water-resistant cover is required, choose SafeSlabHD? which has interlocking panels that can be sealed.
