The solution for this problem is the newly developed HS®-Tree Root Vent with its 160 to 230 mm telescopic cap and its 1.5 m HS® stand pipe. Mainly air but also water and nutriments can be fed to the roots. The upper section is equipped with a UV-resistant, slotted cover and can ideally be adapted to the local installation conditions using the telescopic cap. It also comes with a firmly shaped supporting plate with HS® DN/OD 110 coupling sleeve. The lower section consists of a 1.5 m stand pipe with soil anchorage which is available in a slotted version. This tube is additionally equipped with a geotextile stocking. The remaining annular gap between bore wall and lower section is filled with drainable bulk material such as lava 8/16 mm. The system is especially suitable for new plantings and the remediation of trees.
In connection with this system an HS®-Tree Irrigation Set is available, where common drainage pipes can subsequently be connected to the upper section according to DIN 1187.
The HS®-Tree Root Vent with the upper section made of cast iron is suitable for trafficable surfaces.
