Tree Anchoring Without Anchors

D-MAN® Anchor System - Plati-Mat®

With the ever increasing desire to create beautiful landscapes in challenging urban environments and roof gardens there are many occasions where a standard tree anchoring system cannot be used due to the location of buried services or shallow planting areas. The award-winning D-MAN® is a strong, compact and lightweight system primarily designed to replace the traditional kerbstone or sleeper deadman.

D-MAN® can be used individually or in multiples and cells simply lock / unlock together. It has a distinctive letterbox style wire tendon anchor point and a unique cup for cup water for valuable water storage. D-MAN® is made from recycled plastic and when combined Plati-Mat and our own engineered ratchet tensioner provides excellent stability to the tree.

D-MAN® cells can be easily connected together and stacked to create a structural system to suit any planting area or podium.

The D-MAN® Structural System alleviates many problems caused by planting in restricted urban areas.



  • Cover and protect large planting areas & roof gardens
  • Stack cells, by rotating them 180°, to allow planting areas to be built up.

Deadman System - Plati-Mat®
Designed to satisfy the requirements of a specialist market, traditional deadmen systems have enabled Platipus to offer effective solutions for planting in difficult urban environments, where buried services may be a problem.



The systems use kerbstones or sleepers as anchor points and providing that the soil placed on top of the kerbstones or sleepers has been well compacted before placing the tree in the pit, the systems offer a fast and efficient method of securing rootball trees up to 12 metres high.
