Engineering Bricks

Learn more about engineering bricks

Engineering bricks are the backbone of any heavy-duty construction project where structural integrity and moisture resistance are non-negotiable. 

 

Engineered for high compressive strength and incredibly low water absorption, these bricks provide a robust solution for damp-proof courses, foundations and retaining walls.

 

Engineering bricks are specifically manufactured to have a high dense core, making them significantly stronger and less porous than standard facing bricks. 

 

They are classified based on their physical properties rather than their appearance, though they are available in blue (often slightly stronger) and red colours to suit different regional requirements or aesthetic preferences.

 

Typical uses

Due to their resilience, these bricks are the primary choice for:

 

• Damp Proof Courses (DPC): Preventing rising damp in foundations.

• Groundworks: Constructing manholes, sewers, and retaining walls.

• Civil engineering: Bridges, tunnels, and sewers.

• Steps and cappings: Where water runoff and high foot traffic require a durable surface.

 

How to choose the right engineering bricks

 

• Selection should be dictated by your structural engineer’s specifications. 
• Class B engineering bricks are the industry standard for most domestic and commercial applications. 
• If the project involves constant water immersion or extreme acidic soil conditions, a Class A brick may be required for its superior density.
• Refer to the product specifications for technical information.

 

Before you order

 

• Check your site access for heavy goods vehicles (HGVs), as engineering bricks are significantly heavier than standard aerated blocks. 

• Ensure you have the correct mortar mix ready; due to the low porosity of these bricks, a stronger mortar (often M12 or Designation i) is recommended to ensure a secure bond.

• Use our handy brick calculator to ensure you are ordering the right amount for your project.
