Octaform is North America’s leading tank supplier and have representation and support worldwide. We deliver fully integrated containment tanks designed for speed, durability, and long-term performance in biogas projects. Our stay-in-place PVC formwork system combines structural concrete with a permanent fluid- and gas-tight liner in a single construction process — reducing trades, shortening schedules, and improving quality.

With the right site conditions, tanks can be fully installed in as little as 3.5 weeks, including insulation, cladding, and liner. For larger facilities, multiple tanks can be constructed in parallel, allowing owners and EPCs to protect critical path timelines and significantly compress overall project schedules.

Each tank system includes:

• Structural concrete and steel reinforcement
• Integrated insulation and exterior cladding
• Permanent, gas-tight PVC liner
• 20-year warranty

Octaform tanks are engineered for demanding anaerobic digestion and RNG environments, providing long-term corrosion resistance, reduced maintenance, and predictable lifecycle performance.
