What is Mineral-Based Composite (MBC) Decking?
Mineral-based composite decking is a high-performance alternative to traditional wood and composite decking. Instead of being made with organic wood fibers and plastic, MBC deck boards are engineered using a blend of minerals and polymers. While composite decking is an incredible decking and dock building material, MBC decking takes it to a whole new level. This upgraded formula provides MBC decking with unmatched dimensional stability, an impressive strength-to-weight ratio, and resistance to moisture, mold, and heat.
Why Builders and Homeowners Choose MBC Decking
MBC decking is the most advanced option for customers who want the wood floor look with none of the maintenance headaches. It outperforms conventional composites and beats wood decking on every critical measure.
Unmatched Resistance to Moisture and Mold
Because MBC deck boards don’t contain organic material like wood fibers, they don’t absorb moisture. This means no swelling, no mold growth, and no water damage, even in the most humid coastal conditions.
Superior Dimensional Stability
MBC decking offers virtually no thermal expansion or contraction, even in summer temperatures or dry air. Where wood expands and contracts with temperature changes, MBC stays put. That means fewer loose boards, fewer fastener connection issues, and fewer screw holes widening over time.
Long-Lasting Fade & Stain Resistance
Many MBC boards feature a fade-resistant cap stock, which helps them retain their color and resist staining from food, drinks, and mildew. They hold their look longer and require less maintenance than traditional wood decking.
Strength Without the Bulk
With an industry-leading strength-to-weight ratio, MBC decking is lightweight but offers the same strength as traditional composites and wood in load tests. It outperforms traditional composites and wood in load tests, making it ideal for raised decks, boat docks, or areas with heavy foot traffic.
Cooler Underfoot
Traditional composite boards and wood decking can get hot under direct sunlight. MBC decking retains less heat, making it more comfortable during those blazing summer afternoons.
Low Maintenance (And Pays For Itself!)
While MBC decking carries a higher upfront cost than wood boards or traditional wood composite boards, it pays off over time. With virtually no regular maintenance requirements—no staining, sealing, or worrying about water damage—you save big on labor, cleaning products, and repairs. Plus, many brands offer 25- to 50-year warranties on MBC decking, compared to the 10- to 15-year coverage typical of wood or lower-tier composite material.
Supports a Greener Environment & Sustainability
Mineral-based composite decking is engineered to reduce environmental impact. It contains no organic material that can rot or release toxins, and many products are made using recycled content. Because MBC decking lasts longer, fewer boards end up in landfills compared to wood or conventional composites.
Built to Handle Harsh Environments
From in-ground patios and residential cladding to boat docks and decks that take a beating from sun, salt, and storms, MBC decking is engineered to handle it all. Whether you’re building in a swampy backyard or on the open water, you need a material that won’t crack, stain, or warp during adverse weather conditions with changing temperatures or when moisture sets in.
Easy Installation & Versatile Applications
MBC decking isn’t just tough; it’s also easy to work with. Its lightweight composition makes transport and installation faster and simpler than heavier wood or composite boards. Whether you’re building a complex multi-level deck or a simple dock extension, MBC boards cut clean, screw in securely, and stay in place.

Deckorators: Leading the Way in Mineral-Based Decking Innovation
At Decks & Docks, we know waterfront conditions better than anyone. That’s why we carry products engineered to outperform in the harshest environments. When it comes to mineral-based composite decking, Deckorators is the pioneer. They didn’t just enter the category; they created it. Deckorators’ mineral-based composite decking introduced a patented technology that bonds mineral filler and polypropylene into an ultra-dense, lightweight core. Unlike traditional wood plastic composites, these boards don’t absorb moisture, warp, or expand. Their Voyage and Summit lines use proprietary Surestone® technology, a true mineral-polymer blend with no organic content. That means virtually no thermal expansion, complete resistance to mold and insect damage, and a strength-to-weight ratio that’s unmatched in the decking industry. They’re also rated for ground and water contact, making them ideal for boat docks, in-ground patios, and other challenging builds. And with a 50-year structural warranty and 25-year fade and stain protection, you’re covered for the long haul. Decks & Docks proudly stocks a full range of Deckorators profiles and colors, including picture frame boards for a totally custom design. If you want the original and best in mineral-based composite decking, Deckorators is the name to know, and we’ve got it ready for your next project.
