Before a tree can establish itself at its final location, it must be able to survive a prolonged, critical phase of growth. The classic tripod is not usually an appropriate means of support due to the varying circumstances at the location, extreme climatic conditions and planning requirements.
The GEFA TREELOCK® is the ideal method for secure and invisible anchorage. It provides the tree with the necessary stability during the growth phase, and protects its roots – without the visually unattractive tripod.

Different conditions on site, extreme climatic conditions and planning requirements require flexible and individual solutions for tree fastening. The GEFA ball anchoring TREELOCK® has been specially developed for such situations.
The further development of the GEFA ball anchoring has made waves in the professional world. In the past, numerous customers were able to convince themselves of the advantages of the underground "tree lock" GEFA TREELOCK® - the extremely low installation height, the removable ratchet lever and the quick installation
An innovative ratchet system is used to connect ground anchors to one another and to fix them to the ball. The highlight: The lashing lever can be separated from the ratchet base.
Wide belt straps, which are attached to the ground with flat steel anchors, secure the stand of the tree with TREELOCK® anchoring. In addition, a coconut disc protects the balls of the balls.
One person can install the anchor in a few minutes. For TREELOCK® you do not need any additional aids such as wooden crosses or the like. All you need is a hammer and a hammer. Instead of the hammer, you can also use RAMLOCK®, the special ram for the GEFA drive-in rod.

The Centre for Horticulture and Technology in Quedlinburg has carried out a five-year test headed by Dr. Schneidewind on the underground anchorage systems most commonly found on the market. In addition to the GEFA TREELOCK® system, five other systems were tested for suitability, gentleness to the tree and function fulfilment. The permanently-changing wind conditions in Quedlinburg represented a real challenge for all the anchorage systems. The TREELOCK® was able to convince on all points, such as in the issue of trunk tilt, as being superior to all other systems.
The installation of the GEFA TREELOCK® ball anchor only differs from the old version when it comes to lashing the new ratchet system.
First dig the planting hole as usual, place the tree. Then drive anchors with integrated loops into the recommended soil depth using a drive-in rod and lock in place by pulling. Place the bale protection disc on the bale, guide the ratchet strap through the anchor loops and thread it into the ratchet.
Pull on the locking handle of the lever supplied - the eyes move apart. Guide the eyelets onto the lower part of the ratchet and let the lever engage by releasing the locking handle.
Then ratchet tight as usual. Then pull the locking handle - the eyes move apart - release the lever - done!
Impact aid for driving in the GEFA TREELOCK® ground anchors in connection with a motor ram with SDS HEX connection.
• Back-friendly installation • Less effort • Time saving
• Extremely low installation height for even more flexibility • Wide webbing, fixed into the ground using flat steel anchors, ensures that the tree stands securely. • Innovative ratchet system and ground anchor fix the bale into the ground • An ingenious idea: the ratchet lever used to lash down the webbing can be removed – which reduces the installation height and also provides protection against theft • An additional coir disc protects the ball • A sledgehammer and an impactor rod suffice as tools - no additional aids such as wooden crosses or similar are required • Universal ratchet lever • Theft protection • even lower installation height • less abiogenic material in the soil • short installation time • gentle on the bale • Dismantling not necessary • no installation of additional components • Alignment unproblematic • individual versions • Can also be used for trees with a height of over 90 cm
* larger impact depths increase the tensile strength of the anchors. Use only in natural soil.

1. Dig the planting hole. 2. Put the anchor vertically onto ground. The end of the anchor should face away from the ball. 3. Drive the anchor down to the recommended ground depth. 4. Pull the impactor rod through the loop. 5. Bring the anchor into transverse position by pulling upwards; the loop ends should project out of the ground up to the middle of the ball.
6. Lay the ball protection disc onto the ball. 7. Push the ratchet strap through the anchor loops 8. Pull the handle on the lever. 9. Guide the eyelets over the lower part of the ratchet and engage.
With increasing soil sealing, the greening of buildings is becoming more and more important. Underground car parks, roofs and built-up areas are transformed into designed gardens, sometimes even as reflections of entire landscapes.
Secure anchoring is necessary so that larger trees can also be used here. For such cases, or in the vicinity of pipelines or in unfavorable soil conditions, TREELOCK® is available as special ball anchors for building greenery.
The task of the anchor point is taken over by appropriately dimensioned steel mats. The load from the root ball and substrate serves as a counterattack. Alternatively, z. B. lawn grids, curb stones or eyelets attached to concrete elements can be used.
With the use of the GEFA ball anchoring for building greenery, even large trees can be planted and anchored where this is otherwise not possible:
• in buckets, e.g. B. for mobile green • on roofs or underground garages • in backfilled soils / substrates • in the vicinity of pipes and ducts
Reinforced steel mat anchoring • Loop belts through the reinforcement mat.
• Due to the dead weight of the tree, the reinforcement mat acts as a counterweight.
• Calculation of the reinforcement mat: min times the bale diameter.
Counterweight anchoring
• Straps with heavy counterweights, such as. E.g .: secure lawn grids, curb stones or concrete elements.
Hook anchoring
• Attach the strap to the hooks or eyes of a stable substructure or to buckets.
Two rectangular towers project just under 80 or 112 metres into the sky – cladded in a green robe. Approximately 800 trees decorate the exterior facade of the highrise blocks, as well as 5,000 bushes and approximately 11,000 ground cover plants. This “green coat” is what gave the project its name: “The vertical forest” – which was realised with the aid of the TREELOCK® OBJECT.
This urban future vision was designed by the Boeri Studio architect’s office and the building owner, Manfredi Catella. They were awarded for their work with the International Highrise Award. The two towers on the Porta Nuova have carried out “pioneering work in the planting of highrise buildings” and can be considered as a “prototype for the cities of tomorrow”. These words were spoken by a representative of the German Architecture Museum (DAM), which together with the City of Frankfurt and the Deka-Bank is the sponsor of the International Highrise Award.
Each of the 113 apartments has access to at least one terrace, which looks like a small garden or even a small section of forest. The plants are intended as natural climate control for the apartments and offer the inhabitants exceptional living quality. The woody plants are up to 9 metres high, whereby the varieties have been carefully selected so that they can grow well in their respective positions. Their maintenance and irrigation are all part of the concept, and have been included in the price calculations accordingly.
The executing companies praised the fact the GEFA anchorages were uncomplicated to handle. The different situations on-site could be mastered quickly, without damage and flexibly. The fact that individual equipment was available for different fastening points was emphasised, as well as the individual length adjustment. These features reduced installation times on-site, which proved a significant factor as a total of 800 trees had to be anchored.

With increasing soil sealing, the greening of the property becomes more and more important. Underground garages, roofs and built-up areas are transformed into designed gardens. GEFA TREELOCK® OBJEKT offers secure anchoring for greenery, even with larger trees.
The TREELOCK® ball anchoring is an underground anchoring system for trees, which is available in different sizes and is based on the circumference of the trunk. The TREELOCK® is ideal for secure and invisible anchoring. It gives the tree the necessary support.
The TREELOCK® tree anchoring with guy ropes is the alternative to post anchoring or underground TREELOCK® ball anchoring. Strong steel ropes or red, stretchy textile ropes, attached to the ground with ground anchors, secure the stand of the tree. It gives the tree the necessary support.
A secure hold is a basic requirement for the positive development of young trees in the city, especially with new plantings. The fastening must be strong, protective, quick, gentle and inexpensive. The GEFA Fabritz tree binding and protective hose have been meeting these criteria for years.
In the first few years, young trees must be supported in order to grow straight, not to topple over and to take root well. The TrioFix® system with its three posts and integrated belt is the ideal solution for new plantings. The system is available in two sizes and can be installed by one person.
The long-term test "Comparison of six different underground anchoring systems" by Dr. Schneidewind from the Center for Horticulture and Technology in Quedlinburg has shown that newly planted trees can be anchored with a tripod need a period of at least three years to anchor themselves sufficiently in the ground on their own. There are fewer trees that are secured with underground anchoring.
The reason for this is the stimulation caused by movements at the roots, which is more intense with this anchoring variant. If we assume a "worst case" and assume a period of at least three years, a biodegradable underground anchoring should demonstrably last a period of at least three years in the ground without losing its function, thus allowing the tree to grow straight to ensure.
As part of internal further development, the GEFA commissioned the Federal Institute for Materials Research and Testing (BAM) to examine the selected materials for their durability. The investigation was carried out in accordance with DIN EN 12225 (test method for determining the microbiological resistance by means of an earth burial test). The duration of the laboratory test simulates a period of approx. 4 years transferred into reality.
Thanks to a specially modified formulation of the material, we have succeeded in developing a belt that has been proven to have the required durability in the ground and whose material complies with DIN EN 13432 for biodegradability. The webbing consists of biopolymers based on renewable raw materials that have been specially modified for special use in the ground. The belt straps have been proven to rot and the iron components slowly dissolve as a result of corrosion. We have refrained from using any dyes to color the belts in favor of biodegradability. The GEFA organic belt is therefore delivered in pure white.
Due to the composition of the webbing material, which has been specially modified to meet our requirements, we can offer you organic webbing that securely fixes the tree for the required three years. In addition, the webbing material fulfills the The prerequisite for the “Keimlings-Siegel” of European Bioplastics e.V. This is an EU-wide certificate, which is awarded by the commissioned certification organizations DIN Certco and Vinçotte according to standardized procedures will. This compostability mark is only allowed to be used by organic products that are proven to be biodegradable according to the European standard DIN EN 13432 or DIN EN 14995. It was a long way to find the optimal composition, which has now led us to GEFA TREELOCK® BIO. With this variant of our TREELOCK® systems, GEFA now offers further innovative products for sustainable, ecological landscaping.
The biodegradable underfloor anchoring for raised plant pits. The object variant is always used when no ground anchors can be used. These are mostly situations in which a loose plant substrate has been freshly filled or the existing plant base is roughly stony.
Of course, this system is also suitable for green roofs, but with the clear indication that the belt is made of organic material gradually decomposes and after this time the tree has to hold itself on its own.
Biodegradable stability up to 60cm tree circumference
GEFA Treelock BIO 60 completes the range of GEFA underground anchoring systems With the Treelock Bio 60, GEFA Produkte Fabritz GmbH now introduces an underground anchoring system with biodegradable straps for securing trees up to 60 cm in trunk circumference. The strap bands are made of biopolymers based on renewable resources that have been specifically modified for use in the soil.
This addition completes the Treelock BIO product range of the Krefeld-based company, which now includes the Bio 25, Bio 35 versions, as well as a special version for object greening. For those who want to secure larger trees underground, they can rely on the classic Treelock product range, which offers different variations for almost any tree size.
Both product lines feature wide strap bands, additional root ball protection with a coconut disc, as well as a low construction height and reduced material usage for the tie-down strap, thanks to a detachable ratchet lever as a "tool".
Due to its proven compostability, the webbing base material complies with DIN EN 13432.
