Lignacite ECO 70 concrete blocks are made with at least 70% recycled content. Not only does this conserve the use of primary materials, but it also results in a product with lower embodied carbon compared to most conventional masonry materials.

An independently verified Environmental Product Declaration (EPD) confirms the key environmental data of Lignacite ECO 70, ensuring transparency and sustainability.

Lignacite ECO 70 blocks are medium grey in colour with a close-textured surface. Blocks are manufactured from naturally occurring aggregates and some colour variation between blocks will be discernible. Manufactured to BS EN 771-3, Lignacite blocks are robust and durable with a technical performance that makes them well-suited to most applications.

The blocks’ exclusive mix design (consisting of cement, fine aggregates and recycled graded-wood particles) accounts for their outstanding technical performance.

Mortar

Generally, the mortar type for work above ground level should be designation (iii) / Compressive Class M4. Stronger mixes may be required if blocks are used below ground.

Movement

Vertical movement joints should be considered in accordance with masonry design codes and the recommendations of Published Document PD 6697:2019, at 6.0-7.0 metre spacings. In areas of raised stress, such as above and below openings in external walls, the blockwork may need to be reinforced to restrain movement.

Design

The design of walls using Lignacite Eco blocks should be in accordance with relevant design standards, including BS 8103-2, BS EN 1996-1-1:2022 and the requirements of the Building Regulations.
