The Tree Root Guiding (TRG) root guidance system is designed to prevent root heave on paving and protect cables and pipelines. The special walls with guiding ribs direct the tree roots straight down and ensure that they grow horizontally under the panel. This keeps the tree stable and the paving intact.
Root guidance literally means guiding the roots in a certain direction. Similar to root protection, roots encounter a barrier in root guidance – in this case, a TRG root guidance panel. Our TRG panels are equipped with guiding ribs placed perpendicular to the panel. These ribs ensure that the roots are directed downwards once they hit the panel. Without these ribs, the roots would circulate along the wall, causing the tree to suffocate and lose stability. Once the roots reach the bottom of the panel, they continue to grow horizontally.
A conventional root protection system does not establish root guidance and therefore does not provide stability. Additionally, a conventional protection system can only be used from 2 meters away from the tree. If a root screen needs to be placed within 2 meters of a tree, it is necessary to use root guidance panels to ensure the stability of the tree.
Tree Root Guiding root guidance is applied both for new plantings and after root cutting (renovation) to maintain the beauty and value of mature trees. Furthermore, it minimises the repair and liability costs of damaged pavements and the risk of tripping.
TRG panels have a thickness of 2 mm, guiding ribs, root anchors, and a double top edge. This double top edge prevents root overgrowth. The panel always protrudes slightly above ground level so that roots cannot grow over the panel. The sturdy double edge allows for a visually clean and neat installation. This edge ensures that the edge does not get damaged, break, or cut when the screens are stepped on. A broken screen immediately provides escape opportunities for the roots, reducing the screen’s functionality.
Protect the surrounding pavement on all four sides of the tree with the TRG root guidance panels. Utilise the entire available space within the tree pit for maximum uncompacted soil, sufficient growth space for the tree, and effective root guidance. Ensure there is enough space around the base of the tree trunk and take into account the future mature size.
TRG Sliding Panels are, as the name suggests, extendable panels. These panels are suitable for any size planting hole and ideal for trees completely surrounded by paving, such as on squares and pavements. TRG Sliding Panels form a neat 90-degree angle and have a sturdy double edge that withstands being stepped on. The TRG Sliding Panel is available in two types: TRG45 Sliding Panel and TRG 60 Sliding Panel.
