140mm blocks are a fundamental component in masonry, offering a balance between wall thickness and structural support. By choosing the right specification, you can significantly impact both the load-bearing capabilities and the thermal performance of a structure. They are engineered to meet strict British building standards, ensuring consistency across your build.
We stock both solid dense concrete blocks for load-bearing applications and aerated concrete blocks which provide superior thermal efficiency. These versatile units serve as a reliable foundation for residential and commercial builds alike. Explore our selection below to find the precise strength and finish needed to keep your project on schedule. Secure the structural base your build deserves with our trusted range.
These blocks are versatile workhorses of the construction industry. They are most commonly used for:
Internal and external load-bearing walls.
Cavity wall construction (as the inner leaf).
Beam and block flooring systems.
Foundation work where a robust, reliable base is required.
Selecting the right block depends on your project's technical requirements:
Assess the load: If you need to support heavy floors or roofs, dense concrete blocks provide the necessary structural strength.
Consider insulation: If thermal efficiency is a priority, consider aerated blocks.
Check the environment: Ensure the product is suitable for the intended exposure (e.g. damp proofing or external conditions).
To avoid site delays, confirm your quantity requirements accurately before ordering.
Consider site access for heavy delivery vehicles and ensure you have adequate storage space on-site.
If you are uncertain about the quantity or type, our brick calculator will give you a good idea of how many 140mm blocks you will need for your project.
Make sure you have all of the essential materials and tools for laying blocks, such as cement, trowels, hawkes & floats, damp proof course & membranes, and wall ties.
Build with confidence using our high-quality 140mm blocks, designed to provide exceptional structural integrity for your building projects. Whether you are tackling cavity wall construction, solid walling, or beam and block flooring, our range offers the durability and strength required for professional masonry.
