Anchoring and irrigation systems for trees

D-MAN® Non-Penetrating Tree Anchoring System

With the growing desire to create high-quality landscape designs in challenging urban environments and on green roofs, there are many situations where a standard tree anchoring system cannot be used due to the limited depth of planting areas. The D-MAN® system is a robust, compact, lightweight, non-penetrating solution, primarily designed to replace traditional anchoring systems made of concrete blocks or sleepers.

Description of D-MAN® Anchoring Systems

• Underground, non-penetrating, compact, lightweight and durable tree anchoring solution, compliant with FLL standards
• Cell-based system that can be used individually or in combinations; the cells can be connected/disconnected.
• “Mailbox-style” steel cable anchoring point and a unique water storage cup.
• Recycled plastic material
• Ratchet tensioning device for maximum tree stability.
• Interconnectivity: anchoring cells connect to each other and can be stacked to create a structural system adaptable to any planting area or podium. This allows trees with different root ball heights to be planted at the same level and offers soil architecture design options.
• Drainage function: allows water to drain into deeper layers while retaining a water reserve within the cells.
• Dimensioning: 16 cells/m², minimum 1.5 m² of anchoring system required beneath each tree

The cells must be installed at least 30 cm below the base of the root ball (if this is not possible, the anchoring area must be increased to a minimum of 4 m² per tree, interconnected with adjacent anchoring systems, and the soil above must be compacted to 60% up to the nursery line level).

Structural Systems According to the Size of the Trees to Be Anchored

A. Tree Height: 2.5 – 7.5 m / Trunk Circumference: 25 – 45 cm

• 3 double anchoring points with galvanized wire discs
• 5 m galvanized cable
• 1 ratchet tensioning device
• 3 x Plati-Mat or similar for root ball fixation
• 24 x D-MAN® cells or similar (3 sets of 8 interconnected cells each, 1.5 m²)

The cells must be installed at least 30 cm below the base of the root ball, and the soil above must be compacted to 60% up to the nursery line level.

B. Tree Height: 2.5 – 7.5 m / Trunk Circumference: 45 – 70 cm

• 3 double anchoring points with galvanized wire discs
• 5 m galvanized cable
• 1 ratchet tensioning device
• 3 x Plati-Mat or similar for root ball fixation
• 72 x D-MAN® cells or similar (9 sets of 8 interconnected cells each, 3.5 m²)

For planting large trees of various species, specific anchoring systems capable of meeting the anchoring requirements of large root balls are installed as described below. When planted correctly, these tall trees will ultimately provide an impressive visual impact to landscapes, while also ensuring operational safety and resistance to wind suction.

D-Man Cell Anchoring System

This is an easy-to-use system: the water-retaining cells are connected together, filled, and then anchored to the root ball. The installation kit is included in the package.

D-Man cells can be used individually or connected in multiple units, allowing easy assembly/disassembly in any direction. The cells are made of recyclable plastic and feature a unique shape with significant water retention capacity.

The cells are connected to the root ball with wire using a unique “letterbox”-style system. The cells must be installed at least 30 cm below the base of the root ball, with the soil above compacted to 60%.

Systems can also be used in which the cells cover the entire surface beneath the root ball, to which the root ball is anchored.

Another option is to use 3 or 6 cells, depending on the height and trunk diameter of the tree.

Piddler Irrigation System

The system efficiently directs water and air directly to the tree roots, minimizing water loss. Watering can be done easily with a hose through the cap or using an adapter. It can be quickly assembled and is suitable for all root ball sizes.

From the design phase of any ecological construction project carried out on terraces or roofs, we can provide full support in selecting the systems best suited to the investment, in relation to budget and construction possibilities.

By using anchoring systems, planting tall trees becomes easier, safer, and faster. Irrigation systems help water trees more efficiently, with reduced water loss.

The manufacturers whose materials are used in green roof construction are internationally and locally recognized, and our team—having already completed multiple joint projects with reliable and visually impressive results—can ensure the installation and maintenance of all these components. Through our work, the quality of construction elements in green roof projects is complemented by the professionalism of a qualified and experienced team.

Whether it is an industrial hall designed with an extensive green roof, an office building with an intensive green terrace featuring recreation areas, or a shopping center with a landscaped intensive green roof parking area, our team’s expertise ensures product compatibility and a coherent final result. Protective layers, filter layers, green roof drainage, vegetation substrate, vegetation installed by turf rolls or seeding, together with inspection chambers, edging elements, drainage channels, outlets, and other necessary products, all form part of an integrated system.
