Octaform systems can be customized to build long-lasting aquaculture structures for even the most challenging environments.

Octaform Builds the Best Fish Tanks

From a simple grow-out tank to the most complex recirculating aquaculture system, Octaform systems can be customized to your needs. Our patented system assembles quickly without specialized labor or heavy equipment. Octaform is the only option that forms and protects your tank walls in one step. The finish is built-in, eliminating the need for liners, cladding or sealants. You won’t be waiting for extra trades to seal, protect or clad your concrete tank. When the concrete is cured, your tank is ready.


Maintenance-free PVC Finish

Concrete is already one of the toughest and most long-lasting building materials on the planet – Octaform makes it better. Octaform systems protects the concrete with a built-in PVC finish so you can stop worrying about corrosion, cracks and leaks. Tank maintenance will be a thing of the past. Whether enduring the hot Florida sun or standing strong against tsunamis and earthquakes, Octaform makes tanks that last.

Fish Friendly Tanks

PVC is one of the most durable and reliable polymers in the world. Octaform PVC systems are certified for food and drinking water containment. They won’t support the growth of mold. You can build any shape with Octaform so the fish can move easily beside the surface. The built-in smooth finish protects your fish from rubbing up against a rough concrete surface.

An outstanding product at a competitive price…we’ll use the system again!
