Silca System NZ – The Future of Elevated Decking

In the ever-evolving building industry, durability, compliance, and sustainability are key concerns for architects, builders, and homeowners alike. As a result, the Silca System offers an innovative approach to elevated deck structures, ensuring a strong foundation for tiles, pavers, and artificial turf.

Structural Support That Lasts

Designed for residential and commercial applications, Silca Grates provide a solid, flat surface that allows for seamless installation of heavy materials like natural stone, porcelain, and concrete pavers. In addition, Silca System is made from high-quality recycled materials, making it an environmentally friendly alternative to traditional decking solutions.

Why Choose Silca System?

• Versatile Applications: Ideal for decks, patios, stairs, ramps, paths, bridges, docks, pool areas, and various residential and commercial projects.
• Innovative Construction Product: A revolutionary system supporting any type of paving on timber or aluminium deck joists.
• Environmentally Friendly: Made from 100% recycled materials, offering a sustainable alternative to hardwood decking.
• New Zealand Made: Originally established in the USA and Canada and now manufactured locally in New Zealand.
• Maintenance-Free: Provides a durable, raised patio without the ongoing maintenance required by wooden decking.
• All-Weather Durability: Maintains strength in extreme climates, from the Southern Alps’ snow and ice to North Queensland’s tropical heat and moisture.
• Reduced Fire Risk: Non-combustible pavers prevent hot ash or embers from igniting the deck. In addition, a fire-retardant Silca Grate rated V-0 is available upon request.
• Cost-Effective: More economical than Kwila, Accoya, and other hardwood decking options. It is also significantly cheaper than elevated concrete slabs and can reduce installation labour costs.
• Versatile: Silca System integrates with both traditional building methods and modern construction systems.
• Easy Installation: Quick to install, making it accessible for builders, contractors, and DIY homeowners.
• Creative Design Flexibility: Supports various tile layouts and pattern designs. As a result, it allows the creation of unique outdoor spaces that can enhance property value.
• Superior Load-Bearing Capacity: The engineered design of Silca Grate cells supports heavy loads, helping prevent paver cracking or failure under foot traffic and furniture.
• Effective Load Distribution: Distributes loads evenly across joists and supporting structures.
• Adaptable Cutting: Easily cut around obstacles while maintaining support for surrounding pavers.
• Enhanced Ventilation: Minimal surface contact between Silca Grate and joists maximises airflow. This helps improve ventilation and drying of the subdeck structure.
• Structural: Acts as a structural component, reducing the need for nogging and supporting heavy surface laminates.
• Flexible Paving Options: Allows for various paving patterns and joint designs, including full grout joints, drainage gaps, and French Laid patterns.
• Solid, Flat Surface: Provides a stable base for nearly any type of paving, delivering a firm and reliable feel underfoot.

Perfect for Membrane Applications

With the introduction of Silca Grates on adjustable pedestals, the system is now ideal for membrane decks. For this reason, we recommend the Buzon Pedestal for enhanced performance in commercial settings, ensuring stability and long-term reliability.

New Zealand Made, Ready for Expansion

Originally invented in the USA and updated for the New Zealand market, Silca System continues to evolve. At the same time, the system is expanding into Australia and soon into Europe. As a result, architects and builders in more regions can access a trusted solution for elevated decking structures.
