Concrete Blocks 140mm - Per M2

The concrete blocks measure 440 x 215 x 140mm and are sold per m2 which is 10 blocks.

Often referred to as dense blocks, solid concrete block or 6 inch solids, these blocks are technically 7.3 newtons in strength and are commonly used in many types of construction projects. They are made of a mixture of cement, water, and aggregates, and have a density of 7.3 N/mm^3. This makes them denser than other types of concrete blocks, such as the lighter-weight, medium density or aerated blocks.

The increased density of 140mm dense concrete blocks gives them a number of advantages over other types of blocks. They are stronger and more durable, making them ideal for use in load-bearing applications. They are also less likely to absorb water, which makes them more resistant to frost damage. In addition, their higher density gives them better soundproofing properties.

140mm concrete blocks are typically used in a variety of applications, including:

• Wall construction: They can be used to construct both internal and external walls.

• Foundations: They can be used to construct foundations for buildings and other structures.

• Piers and retaining walls: Retaining walls that support weight and prevent soil erosion can be constructed with concrete blocks.

• Fireproofing: Fireproof walls and compartments can be built with dense concrete blocks.

Concrete Blocks are available in 100mm and 140mm and also different finishes such as 'Paint Grade' which has a finer textured finish when painting. They are typically easy to work with and can be cut and drilled using standard tools.

Are these the right blocks for my project?

When choosing concrete building blocks, it is important to consider the specific application for which they will be used. For example, blocks that will be used in load-bearing applications will need to be stronger than blocks that will be used for non-load-bearing applications. It is also important to consider the climate in which the blocks will be used. Blocks that will be exposed to harsh weather conditions will need to be more durable than blocks that will be used in sheltered environments.

Overall, 140mm 7N concrete blocks are a versatile and long-lasting building material that can be used in a variety of applications. They are strong, durable, and resistant to water and frost damage.

140mm Concrete Blocks technical details:


• Size of block face: 440 x 215mm
• Weight of block: 26.6kg
• Laid weight of block (per m2): 280kg
• Thermal conductivity (internal skin): 1.07 W/mK
• Thermal conductivity (external skin): 1.16 W/mK

If you are considering using concrete blocks for your next project, it is worthwhile to consult with a qualified contractor to ensure that they are the right material for your needs.
