Gravelfix by Granulati Zandobbio: the permeable paving system that stabilizes gravel and pebbles

Designing outdoor surfaces with gravel or pebbles creates a natural, refined aesthetic—but often comes with functional drawbacks: shifting materials, the formation of ruts, and unstable footing. The solution is Gravelfix, the honeycomb grid system by Granulati Zandobbio, which allows for stable, durable, and fully permeable surfaces while preserving the beauty of loose aggregate finishes.

Structure and materials: invisible technology beneath your feet

At the heart of the Gravelfix system is a honeycomb matrix made of pure polypropylene, fully recyclable and engineered for high mechanical performance. The hexagonal cells, 42 mm wide and 32 mm high, lock in loose materials (such as gravel or crushed stone), preventing displacement even with frequent or heavy use.

The modular panels are available in multiple sizes – from 0.3 m² to 2.68 m² – with dimensions of 40×80 cm, 80×120 cm, and 117.6×227.5 cm. Gravelfix boasts an impressive load-bearing capacity of up to 300 tonnes per square metre, making it ideal for both pedestrian and vehicular applications.

Applications: from residential paths to public spaces

Gravelfix is an extremely versatile solution, suitable for a wide range of outdoor environments, including:

• Public and private parking areas

• Bike lanes and pedestrian walkways

• Green roofs and rooftop terraces

• Driveways and access ramps

• Courtyards and residential complexes

• Cemeteries and memorial gardens

• Parks, playgrounds, and landscape areas

A technical solution that blends seamlessly into the landscape, enhancing functionality without compromising design.

The benefits of a stable, permeable gravel surface

Choosing Gravelfix means adopting a well-engineered system that combines sustainability, performance, and design. Key advantages include:

• Fully recyclable product, with low environmental impact

• Multifunctional: suitable for pedestrians, bikes, light and heavy vehicles, and wheelchair access

• Locks in gravel, preventing displacement and rut formation

• Suppresses weed growth, keeping the surface clean and low-maintenance

• 100% permeable, allowing water to drain naturally and reducing surface runoff

• Resistant to frost and road salt, ideal for cold or alpine climates

• No anchoring required: can be installed on slopes of up to 17% with ease

Installation: the foundation of a high-performing surface

Proper installation is essential to ensure the stability and long-term durability of the Gravelfix system. The preparation varies depending on expected traffic load:

• For light traffic (pedestrians, bikes, cars):
  → a well-compacted sub-base of at least 15 cm, topped with a levelling layer of sand or fine aggregate.

• For heavy traffic (vans, service vehicles):
  → a compacted sub-base of at least 25 cm, again topped with a smooth, even surface layer for panel installation.

The dry, anchor-free installation allows for fast application and perfect adaptability, even on gently sloping surfaces.

Conclusion: design freedom with a natural aesthetic

Gravelfix by Granulati Zandobbio offers architects, landscapers, and designers a reliable, high-performance solution for outdoor areas—combining technical functionality with an elegant, nature-inspired finish. A system where form and function coexist, delivering both beauty and durability.
