Yes, the groundwater level is an important factor in determining the height of the Tree Root Guiding root guidance system. Roots generally do not grow beyond the groundwater level, the fully capillary saturated zone. They also typically do not grow into the yellow sand layer in the soil profile. When dealing with a high groundwater level, cables and pipes are often installed within the groundwater, where roots do not grow. In that case, a low panel such as TRG45, 45 cm, can be used. We recommend positioning the panels at least 10 cm above the groundwater level. This ensures that roots do not come into conflict with cables and pipes, while still allowing maximum growing space, as the roots can continue to grow horizontally.
