Bricks & Blocks

Bricks & blocks form the foundation of virtually every construction project, from garden walls and extensions to new-build homes and commercial developments. These essential masonry units provide the structural integrity, thermal performance, and aesthetic finish that quality building work demands. At McMahons, we stock a comprehensive selection of clay bricks, concrete blocks, and specialist units to meet the requirements of any project across Ireland.

Our Masonry and Blockwork Range

We supply masonry products suited to both structural and decorative applications:

Standard concrete blocks: solid and hollow options in various densities for load-bearing walls, partitions, and foundations with excellent compressive strength.
Thermal blocks: lightweight aerated units that improve energy efficiency and help meet Part L building regulation requirements without additional insulation layers.
Facing bricks: machine-made and handmade clay bricks in a variety of colours, textures, and finishes for attractive external walls and feature work.
Engineering bricks: high-strength, low-porosity units ideal for damp-proof courses, manholes, and areas exposed to moisture or heavy loads.
Decorative and reclaimed-style bricks: character options that replicate traditional aesthetics while meeting modern performance standards.

For complete structural solutions, browse our full range of Building Materials, including Cement & Aggregates for mortars and concrete work.

Selecting the right masonry unit depends on the application: consider load requirements, exposure conditions, thermal targets, and the desired visual appearance. Our team can advise on appropriate specifications for your project, whether you need standard 100mm blocks for internal partitions or frost-resistant engineering bricks for below-ground work.

Frequently Asked Questions

1. What is the difference between facing bricks and engineering bricks?

Facing bricks are designed for visible areas and aesthetics, while engineering bricks offer higher strength and water resistance for structural or load-bearing applications.

2. Are concrete blocks suitable for exterior walls?

Yes. Dense and aerated concrete blocks are commonly used for exterior walls, offering excellent thermal performance and structural stability.

3. Can I mix different types of bricks in one project?

Yes, but it’s important to match colour, size, and performance characteristics to ensure a consistent finish and structural integrity.

4. Are aerated blocks good for insulation?

Absolutely. Aerated (lightweight) blocks provide excellent thermal insulation, making them ideal for energy-efficient construction.

5. How many bricks or blocks do I need for my project?

Requirements vary by wall size, bond pattern, and block dimensions. It’s best to calculate based on square metre coverage or request assistance with estimating. Please check out our calculator https://www.mcmahons.ie/brick-block-calculator
