The primary binding material, providing strength and durability to the block.


Includes sand, gravel, and crushed stone, which add bulk and stability to the block.


Essential for the hydration process, which allows the cement to bind the aggregates together.


These can include materials like fly ash, slag, and chemical admixtures to enhance workability, durability, and strength.


variations icon_edited.jpg

Dense Concrete Block

Description: High-density block made with a higher proportion of aggregate, offering exceptional strength and durability.

Applications: Ideal for load-bearing walls, foundations, and basement construction.

Manufacturer: Hanson Thermalite Shield Block

Lightweight Concrete Block

Description: Made with lighter aggregates like expanded clay or shale, reducing weight while maintaining adequate strength.

Applications: Used for partitions, infill panels, and non-load-bearing walls.

Manufacturer: Quinn Lite Pac Aerated Block

Aerated (Aircrete) Block

Description: Contains air pockets, making it lightweight and offering good thermal and acoustic insulation properties.

Applications: Suitable for internal and external walls, providing enhanced energy efficiency.

Manufacturer: H+H Celcon Standard Block

Tools Required

Trowel | Spirit level | Tape measure | Brick hammer

Materials Required

Concrete blocks | Mortar mix | Water | Reinforcement bars (if needed)

Step-by-Step Guide:

  1. Preparation: Clear the site and lay out the foundation lines.

  2. Mix Mortar: Follow the manufacturer’s instructions for mixing mortar.

  3. Lay First Course: Start with a mortar bed, place the first row of blocks, and check alignment.

  4. Add Reinforcement: Insert reinforcement bars if required for additional strength.

  5. Build Up: Continue laying blocks with mortar, ensuring each layer is level.

  6. Final Checks: Ensure all blocks are properly aligned and joints are filled with mortar.

Single Units

Ideal for small projects or repairs where only a few blocks are needed.


Commonly sold in bulk, with each pallet containing around 72 to 88 blocks depending on the size and type. This option is suitable for medium to large construction projects.


For large-scale construction projects, blocks can be purchased by the truckload, which includes multiple pallets.

Environmental Impact

Sustainability Considerations

Concrete block production involves significant energy use and CO2 emissions. However, incorporating recycled materials and using low-carbon cement alternatives can mitigate environmental impact.

Eco-friendly Alternatives

Consider using blocks made from recycled aggregates or low-carbon cement to reduce the environmental footprint.

Waste Reduction

Accurate planning and ordering can minimize waste. Surplus blocks can be recycled or reused in other projects.

Energy Efficiency

Concrete blocks contribute to the thermal mass of buildings, helping to maintain stable indoor temperatures and improve energy efficiency.
