Urban tree planting applications.

The RootForm system is a dual-purpose product with all the benefits of GreenBlue Urban’s Root Director products but with the added function of providing a high speed shuttering system to create a concrete haunch around the tree pit. RootForm is designed to be filled with concrete, providing a base for fixing down tree grille frames and preventing compaction of the tree rooting area immediately adjacent to the root ball.

These systems are designed to sit on top of soil cells directing the surface roots down into the cell areas away from the build-up to FFL.

Features and benefits:

• Modular construction for any sized tree pit.
• Recycled HDPE is resistant to puncture, biodegradation, and photodegradation.
• Suitable for inclusion of steel reinforcement if required.
• Internal ribs prevent ‘root girdling’ – a fatal rooting pattern.
• Deeper root growth improves drought tolerance, tree stability and longevity.
• Guides roots away from areas vulnerable to de-icing salts.
• Prevents pavement ‘root heave’ effectively eliminating trip hazards.
• Assembled in moments ready for concrete pour, no shuttering required.
• Reduces quantity of concrete required with traditional shuttering.
• External horizontal ribbing creates key to external paving layerworks preventing differential settlement.
