Can Composite Decking Be Submerged in Water?

The Effects of Prolonged Water Exposure on Composite Decking Materials

Composite decking has gained popularity due to its durability, low-maintenance requirements, and eco-friendly nature. However, a common concern among homeowners is whether composite decking can withstand long-term exposure to water without significant damage. Understanding the effects of water submersion on composite materials is crucial for ensuring the longevity and safety of your deck.

Potential Warping, Rotting, or Weakening

Composite decking is made from a mixture of wood fibers and plastic, which are designed to resist moisture absorption. Despite this, prolonged submersion in water can lead to several issues:

• Warping: While composite decking is less prone to warping than natural wood, excessive water exposure can cause the material to swell, leading to warping over time.
• Rotting: Although composite materials are resistant to rot, water can seep into any cracks or gaps, potentially causing the material to degrade if not properly sealed.
• Weakening: Long-term exposure to water can weaken the structural integrity of composite decking, especially if it is not treated with proper sealants or coatings that prevent water penetration.

Maintenance Required to Ensure Longevity and Safety

To mitigate these risks, regular maintenance is essential. This includes:

• Regular Cleaning: Keeping the deck clean of debris and dirt can help prevent water from becoming trapped and causing damage.
• Sealing: Applying a high-quality sealant every few years can protect the composite material from water damage. Look for sealants specifically designed for composite decking.
• Inspection: Regularly inspecting the deck for signs of wear, such as cracks or gaps, can help identify areas that need immediate attention before they become more serious problems.

Conclusion

While composite decking is highly durable and resistant to water damage when properly maintained, it is not designed to be fully submerged in water for extended periods. Homeowners should take proactive steps to protect their decks from water exposure through regular cleaning, sealing, and inspections. By following these guidelines, you can ensure that your composite deck remains safe and attractive for many years to come.
