The Fortress Tree Grille is a robust and visually appealing solution for urban tree pit protection. Designed for modern public spaces, this grille enables paving to extend close to the trunk while shielding the tree’s root zone from compaction and footfall. It supports sustainable urban drainage by allowing rainwater infiltration and can incorporate Mona irrigation systems seamlessly (sold separately). The removable inner trays are secured with anti-theft fixings, ensuring tree health maintenance and easy replacement access when needed.
Available in a wide range of single or double tray sizes, the Fortress Tree Grille is ideal for block paving schemes and can be customised to suit other paving styles or project-specific requirements.

Key Benefits
Protects Urban Tree Roots
Prevents soil compaction and root damage caused by heavy foot traffic or street furniture near the tree, ensuring long-term tree health in hard-landscaped areas.
Supports Sustainable Drainage
The open grille design allows water infiltration directly to the tree pit, promoting natural irrigation and helping to meet SUDS requirements in urban environments.
Customisable to Fit Any Paving Scheme
Available in a wide range of sizes and adaptable to different tray layouts, paving types, and bespoke dimensions to suit the specific needs of each project.
Easy Tree Access and Maintenance
Features removable inner trays secured with security fixings, allowing straightforward access for tree replacement, irrigation checks, or pit maintenance without dismantling the entire structure.
Highly Durable and Secure Construction
Manufactured from galvanised steel or stainless steel for long-term performance with the option for powder coating in project-specific colours. Secure fixing methods reduce vandalism risk.
