Concrete Tanks and Digesters

In-Situ Poured

Discover our concrete tank solutions engineered for durability, with a design life exceeding 60 years.Our tanks are constructed to meet rigorous EC 1 Class 1 and 2 specifications, as well as British Standards 8007 and 8110 ensuring robust performance, high operating life and reliability.

Concrete Tanks

Circular tanks

Our innovative formwork system features inner and outer shuttering panels that seamlessly assemble to create moulds for tanks of virtually any diameter and height.

High-strength reinforcing mesh is placed between the formwork, and concrete is poured into the mould. Once the concrete reaches optimal strength, the panels are carefully removed, leaving a precision-finished tank shell.

We offer fully customisable tank sizes and configurations, supported by expert installation teams who deliver efficient, fast-tracked construction on every project.

This approach minimises downtime and offers significant scheduling advantages to our clients.

Choose from standard 0.2mm design or opt for our advanced TCL Post Tensioning System (TPTS), which virtually guarantees a crack-free structure for maximum longevity and performance.

To complement the wall formwork, we also design and build structural tank bases, as well as concrete or alternative roofing systems—providing a complete, integrated solution tailored to your needs.

Rectangular tanks
