The following guidelines take you through the most important considerations you need to make when designing a scheme involving tree anchoring.

Tree sizes

Is there accurate information regarding the overall height and circumference of the trees at 1m from the rootball?

Sail area

What size sail area do the trees have?

Root structure

The trees should be properly rootwrapped, airpot or container grown and of sufficient strength and proportion to support an underground fixing method. When pushed, does the stem move while the rootball, airpot or container does not? If the system does move, then an above-ground guying system should be used. 

Site location

Where are the trees to be planted and what is the site's exposure to winds and heavy rainfall? Has an anchor test been carried out?

Soil conditions

Is the soil on the site compact / undisturbed, or made-up ground? Have large amounts of topsoil been brought in to create planting areas and changes in the profile of the landscape? If so, you may need to use Extra Depth (ED) kits, or D-MAN® / Deadman Systems.

Buried services

Has the planting area been checked for all underground services such as drains, water, gas, electricity or fibreoptic and telecom cables? If services are known to be present, an alternative system such as D-MAN® or Deadman System is recommended.

Loadlocking correctly

Anchors must be properly loadlocked into their working position by applying an upwards force / load on the wire tendon. If the anchors are not loadlocked properly, the tree will become loose when the first winds arrive.
