Why Do You Need

Marine-Grade?

What does “marine-grade” really mean? If you’re building near water—whether it’s a dock, pier, boardwalk, or marina—you need materials that can withstand the toughest conditions. Lumberock® Marine-Grade Composite Lumber is engineered for extreme durability, long-lasting performance, and resistance to the harsh marine environment.

Marine-grade materials are specifically designed to endure constant exposure to:

  • Water & Moisture – Prevents warping, rotting, and swelling
  • UV Exposure – Resists fading and degradation from the sun
  • Harsh Weather – Withstands heavy rain, saltwater, and extreme temperatures
  • Marine Organisms – Impervious to mold, mildew, and insect damage

Lumberock composite decking is not just water resistant—it’s engineered for full immersion without degrading, making it the perfect choice for marine applications.

BUILT TO LAST

Traditional wood and inferior composites break down over time when exposed to water and weather. Lumberock’s high-density polyethylene (HDPE) and mineral-filled composition ensure your decking or dock will stand strong for decades without the need for costly repairs.

NO ROT, NO DECAY, NO WORRIES

Wood absorbs water, leading to rot, splintering, and structural failure. Lumberock is 100% resistant to rot, even in saltwater environments. That means no sealing, staining, or replacing boards—just long-term performance you can trust.

UNMATCHED STRENGTH & SLIP RESISTANCE

Marine environments demand stability. Lumberock’s boards maintain their rigidity and structural integrity over time, even under heavy foot traffic. Plus, our unique embossing provides superior traction, even when wet—helping keep your dock or deck safer.

SUSTAINABLE & ECO-FRIENDLY

Unlike treated wood, which leaches chemicals into the water, Lumberock is an environmentally friendly alternative. It’s made from recycled materials and won’t introduce toxins into marine ecosystems, making it the responsible choice for waterfront properties.
