Root Guiding Material TRG30, TRG45, TRG60, TRG90, TRG105 and TRG120: ¡ High-quality recycled material (50% post-consumer) ¡ Injection moulded copolymer polypropylene ¡ Manufactured in ISO 9002 certified factories ¡ 90° ribs guide tree roots downwards ¡ Reinforced double top rib, resistant to repeated foot traffic and against spring roots to prevent overgrowth ¡ UV-stabiliser additive to prevent adverse effects of sunlight ¡ Ground anchors to prevent the panel from being pushed up out of the soil ¡ Produced in Europe The GreenMax Tree Root Guide was designed to prevent root growth from lifting and damaging paving. Its panels feature special guide ribs which redirect tree roots deeper into the soil. The Root Guide can be used within two metres of the tree. Conventional root barriers do not guide roots and therefore offer no stability and limit the growing space. Research shows that some right-angled 90 degree guide ribs are effective enough to prevent against rotating roots and guide the roots downwards instead. To prevent roots lifting the panels, horizontal ground anchors fix the panels in place. Our panels meet all requirements of root guidance. In addition, the TRG panels are also equipped with a double top edge. The rim prevents root growth over the panels and prevents cracking entry of the screens. Root guidance has been in use since 1976, invented by the then founder of DeepRoot. The system has proved itself being in thousands of projects ever since. However, it is still essential to use the product in the correct way, which is very simple. TRG30, TRG45 and TRG60: ¡ Panels are 60 cm wide TRG90, TRG105, and TRG120: ¡ These panels can be interlinked in order to bridge any cables or piping encountered ¡ Panels are 75 cm wide Dimensions panel Type Panels height For tender descriptions and installation manuals: ww

Application of Root Guiding Panels all around installation: Type TRG45, TRG60 Protect the surrounding hard landscaping on all 4 sides of the tree with root guide panels. Use the maximum available space within the tree pit to ensure maximum uncompacted soil and free root space for the tree, and a good quality root guidance. Take enough space for the trunk flair as the tree grows to reach its mature size. A Tree Root Guiding panel in an angle of 90 degrees. The corner can be pulled in and out and can be connected on both sides to a Tree Root Guiding Panel so it can be used at all projects of...

Root Barriers Application of low panels (30, 45 or 60 cm heigh) Root guiding panel Tree sand Curve Pavement Street sand: > 3 Mpa compacted Tree sand: < 2 Mpa compacted or treated with air injection Existing soil Also applicable in tree granulate For tender descriptions and installation manuals: www.greenmax.eu

Application of Root Guiding Panels linear installation: Linear installation (all types) With Tree Root Guiding you ensure maximum protection of the hard landscaping. By using a linear application you give the tree maximum available root space and stability, therefore improving the health of the tree. To protect the hard landscaping the root guiding can be placed directly alongside of the pavement. For cables and pipes, we use the 90, 105 and 120 cm high panels to prevent tree roots from possibly damaging these cables and / or pipes. These types are therefore applied if the trees are too...

Root Barriers Applications of high panels (90,105 and 120 cm heigh) Other applications root barriers: Root pruning during renovation work Special applications By some pruning of existing tree roots and the use of a TRG Root Guide you can prevent the tree eventually being removed; reducing the need for future root pruning time after time. Root Guidance can also be a solution, for protection against root damage at exceptional situations such as tennis courts, slopes, cemeteries, retaining walls etc. Because of the different dimensions GreenMax TRG panels can be used in different areas with...

Functional requirements of root guiding panels: 1 Top view of vertical guide ribs on the panel Only a right-angle with a height of at least 10 mm will prevent roots from continuing their way horizontally along the screen. Vertical 90° guide ribs are perpendicular to the wall at a 90-degree angle. Research has shown that guide ribs at exactly 90 degrees lead the roots downwards; this is not the case with other angles. Source: James Urban USA 1989 Vertical ribs exactly 90 degrees Top view: roots will be guided down vertically 2 Horizontal distance between ribs 15 cm at most, uninterrupted...

Root Barriers 4 Ground (root) anchors ensure that the screen is not pushed up Root growth around the horizontal ribs prevents the guide screen from being pushed upwards. The roots hold the panel, as it were. It is important that these horizontal ribs are perpendicular to the flat surface of the screen and have sufficient surface area, so that the panel does not shoot past the roots when pulled or pushed. The panel, with the side of the guide ribs and root anchors, must always face the tree. It is important for the surface (the surface that prevents it from pushing upwards) of the root...
