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:
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.
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.
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.

The revised range of Lignacite Concrete Blocks
Lignacite’s block manufacturing plants located in Norfolk and Essex, are responsible for producing over 100,000 blocks per day, enough blocks for building approximately 100 houses. The company works closely with many of the leading builders merchants throughout East Anglia and the City (South East) as well as supplying many major house builders and contractors.
Formed in 1947 Lignacite has continually strived to develop innovative mixes and designs for their building blocks; more recently testing and successfully utilising many recycled materials in an effort to produce more sustainable products.
The blocks have been used in major city projects, many of these in London, and the fleet of FORS Gold accredited lorries enable the company to deliver to almost any site in the capital. An important consideration for contractors in cities. Recent examples include the development of Battersea Power Station, Chelsea Barracks and the new Google Headquarters.
The established range of ‘above and below ground’ concrete blocks have many key benefits for the build process including high fire resistance, excellent sound insulation, good thermal performance and all with varying degrees of recycled content, giving sustainable benefits to your project now and throughout the life span of the building.
What makes Lignacite blocks different
The blocks have a unique mix of sand, grounded wood particles and cement, resulting in the blocks requiring no energy to cure as the exothermic reaction of the cement in the mix produces all the natural heat required. Conventional concrete made with stone ultimately shatters under intense heat. The wood in the Lignacite block is locked up in the matrix of the block thus denying oxygen to the flames. This means that a Lignacite blocks calcifies and hardens in a fire, giving a superior fire rating and performance. The fact that wood locks up C02 due to photosynthesis has meant that more recently its environmental credentials have been even more widely recognised, thus adding benefits to projects using Lignacite blocks.
Fibo 850 is an ultra lightweight concrete block manufactured from expanded clay aggregates and a mixture of other naturally occurring raw materials and cement. The clay aggregate is produced from carefully selected clays which through heat expansion are bloated to create a low-density porous aggregate with numerous cavities.
Lignalite close textured Paint Grade blocks are a lightweight building product manufactured to the requirements of BS EN 771-3 using carefully selected lightweight aggregates. The blocks have a face size of 440mmx 215mm and are available in a block width of 190mm. Their use will assist designers and contractors in meeting the requirements of the Construction Design and Management Regulations.
AshGP is a medium dense 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. AshGP can be used externally where rendering or cladding is to be applied to the wall.
Lignacite a medium dense block is available in Fair-Face, Paint Grade and Standard. Fine textured, loadbearing units, suitable for facing and general-purpose applications. Lignacite SP is available in a 140mm width solid block. It consists of a specially formulated mix which reduces the block density to produce a solid block under 20kg unit weight.
Lignacrete dense blocks are suitable for a wide range of applications. They have excellent levels of sound insulation and high strength capability, making them especially suitable for use in separating and partition walls. They can also be used as infill blocks in beam and block flooring systems.
Lignacite committed to a Sustainable Strategy for Masonry
In 2012 Lignacite Ltd committed to a ‘Sustainable Strategy for Masonry’. This initiative has been the catalyst to enable us to respond to the construction industry’s need for industry-wide reporting of sustainability performance as well as delivering on our commitment for continuous improvement. 2017 continues to see Lignacite striving for improved manufacturing processes and products.
All Lignacite’s blocks contain recycled materials, one is consistently chosen for its sustainable credentials – ‘Lignacite’.
LIGNACITE AND LIGNACITE GP – Medium Dense Blocks (http://www.lignacite.co.uk/concrete-and-facing-masonry-blocks/concrete-blocks/medium-dense/lignalite.html)
The ‘Lignacite’ block, with key benefits for the build process including high fire resistance, excellent sound insulation, good thermal performance, a range of face finishes and with a recycled content of up to 48% has continued to reinvent itself over the years. The wood was first used because it was plentiful and there was a general shortage of building blocks just after the war. It transpired that this material not only produced a lighter block than conventional concrete, but that it made for lighter, smoother block.
Conventional concrete made with stone ultimately shatters under intense heat. The wood in Lignacite is locked up in the matrix of the block thus denying oxygen to the flames. This means a Lignacite blocks calcifies and hardens in a fire, giving a superior fire rating and performance.
The fact wood locks up C02 due to photosynthesis has meant more recently its environmental credentials have been even more widely recognised, thus adding benefits to projects using Lignacite blocks.
The Architects of some of the country’s most iconic buildings made have this choice.
The Shard – (http://www.lignacite.co.uk/project-library/the-shard-2.html) designed by Renzo Piano, uses 140,000 Lignacite (with the Carbon8 aggregate) blocks in its four basement levels, providing a substantial base for the entire tower.
The Gherkin, 30 St Mary Ax, – (http://www.lignacite.co.uk/project-library/30-st-mary-axe-the-gherkin.html)designed by Norman Foster and Ken Shuttleworth again used 10,000m in the basement area.
