General Dimensions and Properties
Material |
Approximately 70% recycled scrap tire rubber, 25% recycled HDPE and / or PP plastic, and 5% additives (to address UV stabilization coloring, etc.). |
Sizes |
Paver: 2.8" x 5.8" x 2.5" (W x L x H) Grid: 11.8" x 11.8" x 1.2" (W x L x H) Note: 8 pavers + 1 grid will provide 1 sq-ft of coverage and will be 3" tall assembled. Sand is used to fill joints. |
Weight |
Paver: 0.91 lbs Grid: 3.7 lbs 1 sq-ft (assembled): approximately 11 lbs. |
Surface |
Paver top surface is slightly textured with a 1/8" radius around the perimeter. The vertical corners of each paver have a 3/16" radius. |
Maintenance
VAST Composite Paver Systems require virtually no maintenance other than an occasional replenishment of joint sand. Chemical spills (e.g., petroleum, paint, etc.) should be cleaned as soon as possible with an appropriate industrial cleaner and rinsed thoroughly with water. Chemical spills / stains left untreated over long periods of time may degrade the surface finish and integrity of the product and are not covered under warranty.
