Installation Guide

The WANE Tree Preservation System can be installed in six easy steps. Follow our installation guide to see how easy it is to install a WANE Tree Preservation System!

Trained personnel using the required 4" drill can install approximately five units per hour per man.   



  1. Position a standard pavement core drill (4" diameter) where unit is to be located and drill through the hardscape and base (in most cases 6" deep).

  2. Extend the hole into the subsoil to a total depth of 14" for a 12" WANE unit and a total depth of 8" for a 6" WANE unit (the hole can be drilled deeper depending on the amount of backfill desired).

  3. Install backfill material to bottom of unit (approximately 2"). Pea gravel or equivalent can be used.

  4. Slide the WANE unit into place, resting on the pea gravel. On most paved surfaces, the unit can be secured in place with epoxy or other outdoor rated adhesive. In normal use, it is often unnecessary to secure the unit at all because of the precise fit.

  5. Broom sweep and remove all excavated materials.  CAUTION: Do not use a worn drill bit in concrete. It will cut an undersized hole and the WANE unit will not fit properly.
