Root protection for trees in an asphalt environment

The value of a tree increases with age. It creates living space for humans and animals, provides oxygen, stores carbon dioxide, filters dust in cities, serves as a windbreak and provides shade and forms a symbiosis with other living creatures. These strengths flow into the calculation of the so-called economic value. This value, for example based on a 100-year-old beech, is around 300 times higher than your purchase price. The development of high-quality root bridges that support the healthy development of existing trees is all the more important to us.

The RADIX A root bridge is always used when existing trees are to be integrated into an asphalted environment such as streets or areas and an area utilization up to the respective tree is desired.



Depending on the design, our root bridges can withstand a dynamic wheel load of 1.5 t (for pedestrians and cars in calmed traffic zones) or 5.0 t (emergency vehicles and trucks, but cannot be used under roads). Due to their modular design and individual production, they are suitable for every building project. Even small height differences or gradients can be compensated by the variable screw foundation. The use of the foundations is correspondingly variable, so that the sensitive root system or lines do not pose an obstacle. Likewise, the pavement stop edge is adjustable according to your building requirement.
