Lightweight Concrete Blocks

About Our Lightweight Concrete Blocks

Our lightweight blocks are used for blockwork, internal walls, and structural builds where strength, handling, and thermal performance need to work in unison. Lightweight concrete units have become standard on modern sites thanks to their easier lifting, reliable compressive strength, and predictable workability.

Whether you are working on a new build, extension, garage, or commercial partition, these blocks provide a practical, efficient solution for creating straight, stable walls without the excessive weight associated with dense concrete products.

Our Range of Lightweight Blocks

Our selection of lightweight concrete blocks focuses on 7N-rated units in the most widely used thicknesses, including our 7N lightweight 100mm concrete blocks and 7N lightweight 140mm concrete blocks.

These blocks combine solid strength with reduced density, making them easier to manoeuvre on scaffolding, during repetitive lifting, or when cutting openings and detailing. The consistent sizing is helpful for masons, enabling them to maintain clean, level courses while tying into existing blockwork or building continuous elevations.

Lightweight construction also supports improved thermal performance, making these blocks a strong choice for inner leaf builds and insulated wall build ups.
