This type of decking is recommended for commercial boat docks or those that see significant traffic and heavy boats.
2.5 PVC Composite Decking
PVC composite decking is made entirely from synthetic materials, usually a blend of polyvinyl chloride (PVC) and other plastic compounds. Unlike wood-based composite decking, PVC decking does not contain wood fibers, which means it is impervious to rot and moisture.
Benefits of PVC Composite Decking:
- Moisture Resistance: PVC decking is highly resistant to moisture and will not absorb water, making it an excellent option for docks exposed to water.
- Low Maintenance: It requires very little maintenance compared to wood or wood-based composites. There’s no need for sealing, sanding, or painting.
- Lightweight: PVC decking is typically lighter than both capped and solid-core options, which can make installation easier.
PVC decking is ideal for regions with high moisture levels and is also commonly chosen for residential and small commercial boat docks.
2.6 Groove-Edge Composite Decking
Groove-edge composite decking features a design where the edges of the boards have a groove that allows for hidden fasteners to be used during installation. This results in a clean, smooth surface with no visible screw or nail heads, contributing to the overall aesthetic of the dock.
Benefits of Groove-Edge Composite Decking:
- Sleek Appearance: The hidden fastener system results in a more polished, seamless look.
- Reduced Risk of Injury: Without visible nails or screws, there is less risk of tripping or injury from exposed fasteners.
