    Polyfab Provides

    Fabricated plastic tanks for water and waste built to any geometry. Most tanks are made with flat surfaces. We can also curve thin walled (1/4 and 3/8 inches) tanks. Our preferred material is natural polypropylene because we get excellent weld quality with that material. We also use HDPE and PVC on request.

    Marine Water & Waste Tanks:

    • Welded construction
    • Optional gasketed cleanouts
    • Internal baffles
    • Design review
    • Flush exterior fittings on top and sides
    • Flush internal fittings on bottom
