FormWork Tanks

Octaform forms and protects your tank walls in one step. Our patented system assembles quickly without specialized labor or heavy equipment.  The watertight panels provide a finish that is built-in, eliminating the need for liners, cladding or sealants.

Formwork Tanks

With Octaform, forming a curved wall poses no more difficult than a straight one. Our patented system is custom manufactured to your specifications, so you can cost-effectively form just about any design in a fraction of the time of traditional forming.

Octaform’s watertight finish is built-in. You won’t be waiting for extra trades to seal, protect or clad your concrete tank.

Sealed and Watertight

Octaform’s patented SnapLockTight™ panel creates a completely sealed wall surface that is watertight and gastight. The panel is ideal for environments that are sensitive to bacteria, mold, and mildew such as food processing and wastewater treatment. It is CFIA (Canadian Food Inspection Agency) approved. No caulking is required where panels join.  We recommend products that will seal the ceiling and roofing interfaces.

SnapLockTight is supplied as a flat panel in white. Custom colors are also available.
