Made from up to 95% recycled materials, patented VAST Composite Pavers are the first socially responsible paver alternatives in the industry, and can contribute to LEED® building credits. One-third the weight of traditional pavers, VAST® pavers are installed in an innovative grid system that dramatically reduces labor expense and improves installation quality and design flexibility. VAST Composite Pavers are now available in both the 3" x 6" size, with the actual size of the pavers with grid being 11.8" x 11.8" or the NEW 4" x 8" size, with the actual size of the pavers with grid being 16" x 16". The 3" x 6" pavers are available in all six colors, with the 4" x 8" pavers available in 5 colors excluding Polo.
