Lignacite are a leading manufacturer of concrete and masonry products and have one of the most efficient and modern manufacturing sites in the U.K.
Sustainable and Environmentally Sensitive Manufacturing
Lignacite sets the standards for sustainable and environmentally sensitive manufacturing. Our curing chambers re-use heat given off by the exothermic reaction between cement and water and when additional heat is needed, gas emissions are pumped back into the chambers, where blocks absorb CO2.
All water used at Brandon comes from a on site borehole, and is recycled at up to 5000 gallons / hour. Sand and aggregate quarried on land adjacent to the plant saves around 36,000 lorry journeys over the period of extraction. The land is then restored on an annual basis for wildlife conservation.
Main Product Ranges:
Concrete Blocks
All our products are Kitemarked as conforming to BS EN 771-3 Aggregate Concrete Masonry Units. They comply with category 1 Masonry Units and are manufactured under a quality assurance scheme assessed and certified to BS EN 9001:2000 by the British Standards Institute.
Lignacite concrete blocks comprise a range of medium density loadbearing units, used in internal or external walls. Lignacite blocks contribute to sound environmental practices as they contain graded wood particles, a selected waste wood product as an alternative aggregate. They also provide exceptional sound reduction qualities.
Concrete Blocks - Lignacite Ash GP:
Ash GP is a medium density concrete block which is robust, durable and suitable for a range of walling applications. Typical uses include the inner leaf of cavity walls when used with cavity insulation, separating or partition walls, and infill blocks in beam and block flooring systems. Ash GP can also be used externally where rendering or cladding is to be applied to the wall. Ash GP blocks provide a strong background for holding fixings. Ash GP is produced using at least 35% of recycled aggregate (by volume) thereby conserving valuable sources of primary material.
Concrete Blocks - Fibo850 Blocks:
Fibo850 is an excellent light weight house builder block. The block is manufactured from expanded clay lightweight aggregate, and contains up to 24% recycled aggregates by volume.
Lignacrete is a robust and durable block that provides a good background for fixing, and that has excellent acoustic properties and thermal capacity. Lignacrete blocks are used in internal or external walls and manufactured from cement, sand and dense aggregates, and contains up to 20% recycled aggregates by volume.

Lignacite - An introduction to concrete coursing blocks
When it comes to achieving precision and efficiency in construction, coursing blocks are an invaluable building material when used in combination with full-sized blocks. Whether you're working on a residential build or a commercial project, coursing blocks offer flexibility and structural support that enhance the appearance of the project and reduce waste.
In this article, we’ll explore what coursing blocks are, their uses and the benefits they bring to all types of building projects.
What are coursing blocks?
Coursing blocks are used in masonry work to ensure accurate height adjustments and alignment in block walls. Their name comes from their role in helping maintain the height of ‘courses’, which are the continuous rows or layers of bricks or blocks in a wall. By filling small gaps in the wall, coursing blocks ensure it remains even and level throughout construction.
Coursing blocks come in a variety of sizes, typically smaller than standard blocks, allowing for flexibility and precision in building. Common thicknesses in the UK include 100mm and 140mm. The height is usually 65mm or 140mm, which corresponds to the height of standard bricks and blocks. Their installation follows normal block laying practice, making them easy to incorporate into any project.
In addition to their primary use in height adjustment, coursing blocks are ideal for detail work around windows, doors and corners where accuracy is required.
At Lignacite, we offer concrete coursing blocks within all of our product ranges, so you can achieve uniformity in performance across your project. Our blocks are available in 100mm and 140mm widths, with pack sizes ranging from 156 to 208 blocks. Several compressive strengths are also available, from 7.3N/mm2 to 22.5N/mm2, making them suitable for all types of general coursing work. We also provide lightweight options to meet specific project needs.
What are concrete coursing blocks used for?
Their key functions include:
Height adjustment
Wall heights do not always correspond to full block coursing. To avoid cutting and wastage of full-sized units, coursing blocks help builders to construct walls to the required height with little or no disruption to the laying process.
Filling gaps
They are often used to fill gaps above doors and windows, and between floor joists, while maintaining the performance and integrity of the wall.
By using coursing blocks, builders can maintain the correct spacing and levels in masonry work, ensuring that the finished structure is both stable and aesthetically pleasing.
The benefits of using concrete coursing blocks in your project
Coursing blocks offer a range of benefits that make them an essential material for construction projects. They allow for precise height adjustments and alignment of brick or block walls, helping builders achieve even courses that contribute to both the strength, appearance and overall integrity of the structure.
Available in various sizes, these blocks provide flexibility, allowing for easy adjustments without the need to cut larger blocks down, which saves both time and effort. By reducing the need for cutting, coursing blocks also minimise material waste, making construction more efficient, cost-effective and sustainable.
They are designed to work seamlessly with full-sized concrete blocks, ensuring compatibility in terms of density, thermal conductivity, moisture movement and finish. For instance, if you use the full-sized blocks and coursing blocks from the same product range, you can treat them in the same way so there is consistency in the finished building.
About Lignacite coursing blocks
All of our standard-sized blocks are available as coursing blocks. Ash GP and Lignacrete coursing blocks are always in stock, while other ranges are available to order. Speak to our Quoting Team to find out more and place an order.
Lignacite - Sustainable block launch: ECO50 and ECO70
We’re delighted to announce the introduction of ECO50 and ECO70, which put recycled materials front and centre of concrete block production.
At Lignacite, we’re dedicated to researching and developing sustainable solutions for concrete block manufacture. That’s why we’re proud to bring two new products to market: the Lignacite ECO50 and ECO70, featuring 50% and 70% recycled content respectively.
This development underscores our commitment to sustainability and the reduction of the environmental impact of construction materials.
Striding towards sustainability
As a business focused on reaching net zero emissions by 2030, 20 years before the government deadline, we’re also conscious of our customers’ desire to reduce their impact on the environment. Finding new ways to cut the carbon footprint of our blocks is therefore a key business priority.
We’ve worked extensively on optimising our energy use, building a more efficient factory, and switching our on-site vehicles to green fuel HVO (hydrotreated vegetable oil). With these improvements in place, we turned our attention to the composition of the blocks.
Using recycled materials in our blocks is not a new concept for us. For instance, our flagship Lignacite block already contains recycled wood particles. However, we wanted to create blocks that made even greater use of sustainable aggregates.
The result is our Lignacite ECO50 and ECO70 blocks.
Lignacite ECO50 and ECO70
The new additions to our range feature high proportions of recycled material. In the ECO50 block, this stands at 50%. In the ECO70 variant, recycled content makes up 70% of its constituent parts.
The mix contains recycled materials sourced within the UK, as local as possible to our factories. These materials are compliant with ISO 14021, the international standard for self-made environmental claims.
Both blocks are medium dense, making them ideal for a range of applications. They are also both available in 100mm or 140mm sizes, with compression strength of 7.3N available initially. The ECO50 block also has a paint grade finish.
EPDs are currently in progress.

To learn more about the ECO50 and ECO70, contact our Sales team. You can call them on 01842 778485 or fill out an enquiry form.
Both ECO blocks are made to order and have a lead time of 13 weeks. We also offer customers in London an eco-friendly delivery option via HVO-powered vehicles, which will reduce carbon emissions by up to 95%.
