Water Absorption Test Results

ABOUT THE TESTING   |    SLIP RESISTANCE   |    STRENGTH   |    WATER ABSORPTION

The lowest water absorption rate in fresh and salt water.

Independent, accredited testing proves that the water absorption rates of some composite decking products may increase significantly when exposed to water for an extended period. Composite decking products with higher water absorption rates may experience dimensional change, decreased mechanical performance and are more susceptible to mold. When submerged in salt water, to simulate coastal applications, some products had an increase in their water absorption rates of more than 90%.
