Block Specialists

Lignacite’s manufacturing plants in Suffolk and Essex are responsible for producing over 120,000 concrete blocks per day, enough to build approximately 100 houses.

Working in close partnership with leading architects, specifiers and builders’ merchants throughout East Anglia, London and the South East, our range of dense, medium-dense and lightweight blocks is supplied to many of the country’s major housebuilders and commercial contractors.

The sustainability of our concrete blocks is core to the Lignacite philosophy. Our blocks have a high level of recycled aggregate content and have been used in countless major city projects throughout the years, many of which you will recognise as part of the modern London skyline.

We pride ourselves on supplying the blocks you need in the manner you need them, from putting them on pallets to shrink wrapping. And with our fleet of FORS Gold accredited lorries, we can deliver to almost any site in any location.

From their non-combustible components to low thermal conductivity, our experts explain why concrete outperforms materials like steel when it comes to fire safety. 🛡️

We’re amping up our sustainability efforts💡

As many of you know, we work tirelessly behind the scenes to monitor our production processes and minimise our environmental footprint. 💪

One of our headline results?

In just two years, we slashed our electricity usage by a whopping 26%! 🤯

We went from using 1.04kWh/m2 in 2020 to a mere 0.77kWh/m2 in 2022! 📉

But wait, there's more! 

We upgraded all our production lights to energy-efficient motion sensor LEDs, ensuring we only use electricity when needed, and reducing waste. ⚡

World-Renowned Projects

Although our blocks have roots in the world of agriculture, they have since been used in a plethora of world-renowned developments.

These include The Gherkin, The Shard, The London Olympic Stadium, Canary Wharf, and both Heathrow and Stansted Airports.

Landmark developments such as Google’s UK headquarters need construction materials that can match the quality of the architectural vision. When it came to finding the ideal concrete block partner for this innovative project, contractors Lyons & Annoot turned to Lignacite.

When Lyons & Annoot was commissioned to work on the massive regeneration of The Whiteley, it turned to Lignacite to provide concrete blocks that meet the project’s strict weight requirements.
