Advantages of Polyethylene & Fiberglass Septic Tanks


  • Easy Installation - No heavy equipment is needed to transport or install our septic tanks. This is a valuable advantage in rough or inaccessible areas and in wet weather conditions.
  • Durability - Polyethylene, because of its excellent corrosion resistance and chemical compatibility is the ideal material for on-site applications.
  • Non-Porous Material - Roots will not penetrate poly septic tanks and fiberglass septic tanks as they can with concrete septic tanks.
  • Easy to Repair - If damaged, poly and fiberglass septic tanks can be repaired easier than concrete or steel septic tanks.
