Powering Stronger Concrete: Bespoke Chemical Tank for Precast Facility

Meeting the Challenge: Storing Specialist Slurry for High-Performance Concrete

Tanks, Pumps & Equipment Ltd (TPE Ltd) was approached to develop a dosing solution for a precast concrete manufacturer using a unique chemical slurry. The additive, dosed directly into the concrete mix, reacts with calcium hydroxide to produce denser, more durable concrete — offering enhanced strength and resistance to frost, chemicals, and abrasion.

However, this slurry has a high specific gravity (SG), placing demanding requirements on storage infrastructure. It also needs constant agitation to remain in suspension, with precision dosing capabilities to ensure consistency in every batch.

The Solution: A Purpose-Built Chemical Tank System

Tuffa supplied a 15,000-litre bunded chemical tank, manufactured from high-spec polyethylene to withstand aggressive substances and heavier liquids. The tank’s robust design made it ideal for the job, with one of the highest off-the-shelf capacities available in the UK for bunded chemical storage.

TPE Ltd integrated the tank into a complete chemical handling system tailored to their client’s needs. The setup included:

A gantry-mounted agitator with a timer to keep the slurry in motion
Recirculation pump for consistent mixing
Ultrasonic level sensor and high-level alarm for safe monitoring
A bespoke weighing and dosing system with built-in redundancy for pump failure

All mechanical and control systems were designed, built, and installed by TPE Ltd in-house, ensuring a seamless fit with the production process.

The Outcome: Efficient, Reliable, Built to Withstand the Demands

This installation has provided the precast plant with a reliable chemical storage and dosing solution that supports production efficiency and concrete quality. The use of Tuffa’s tank ensures long-term durability and easy integration with specialist systems.

“The fact that your tanks can cope with the increased SG is a real bonus to us — not to mention them being the largest ‘off-the-shelf’ bunded tanks on the market.”
