Underground Tanks, and Vaults

Undergrounds-Tanks

Underground tanks may be protected from root intrusion by placing Biobarrier across the top and securing to the sides of the tank before backfilling. Biobarrier may also be placed on the sides and/or bottom of the tank. If a drainage system is provided around the tank, Biobarrier may be used as the drainage fabric as well as to prevent root intrusion.

Site-specific design is required.
