Blue Engineering Bricks

(2 Products)

Blue engineering bricks, recognised for their unique hue and outstanding durability, are a cornerstone of high-standard building projects. These Class B bricks are synonymous with structural integrity, exhibiting an impressive compressive strength of over 75N/mm². They also boast a low water absorption rate, making them perfect for combating harsh weather conditions, including frost. Moreover, their resistance to chemical exposure further enhances their suitability for a variety of demanding environments. From crafting sturdy retaining walls to executing robust damp-proof courses, blue engineering bricks prove their mettle time and time again.

What Are Blue Engineering Bricks?

Blue engineering bricks, Class B in classification, are not your ordinary bricks. 


Class B, the category to which they belong, is assigned to bricks that demonstrate high compressive strength, a minimum of 75N/mm², and low water absorption, no more than 7%. 

These bricks also possess F2-level durability against freeze-thaw cycles and an S2 level of active soluble salts content.

What does all this mean? In simple terms, these bricks are built to last. They're hardy against harsh weather conditions and stand up to high levels of pressure, perfect for heavy-duty applications where ordinary bricks might fail.

Blue Engineering Bricks Applications

  • Retaining Walls: Their high compressive strength makes them ideal for solid, durable retaining walls.
  • Damp Proof Courses: With low water absorption, blue engineering bricks are excellent for damp-proof course applications, resisting moisture penetration in buildings.
  • Manhole Cover Surroundings: Given their hardy nature, these bricks are perfect for heavy-duty applications such as manhole covers.
  • Underground Structures: Their strength and resistance to ground moisture make them a suitable choice for underground structures.
  • Door Reveals and Window Sills: Their smooth, uniform look makes them an attractive choice for door reveals and window sills.

Blue Engineering Bricks Key Features

  • High Compressive Strength: Blue engineering bricks deliver a compressive strength greater than 75N/mm², perfect for building robust and enduring structures.
  • Low Water Absorption: With low water porosity, they can effectively resist damp proof courses and frost attacks.
  • Frost Resistant: Their low water absorption property makes them highly resistant to frost attack.
  • Versatility: From garden walls to manhole cover surroundings, these engineering bricks offer unmatched durability and versatility.

Class B Engineering Bricks 

For an engineering brick to qualify as Class B, it must exhibit the following features:

  • The compressive strength should at least be 75N/mm2
  • The water absorption should not exceed 7%
  • It should have F2 level durability against freeze-thaw cycles
  • The content of active soluble salts should be at an S2 level


Frequently Asked Blue Engineering Bricks Questions

Can Blue Engineering Bricks Be Painted?

Yes, blue engineering bricks can be painted, but it is not often done due to their distinctive colour, which is usually a feature sought for its own aesthetic appeal. 


If you do choose to paint them, ensure you use high-quality masonry paint to achieve the best result.

Do Blue Engineering Bricks Require Special Mortar?

No, blue engineering bricks don't require a special mortar. 

However, a strong mortar mix is recommended to match the strength of the bricks and ensure a durable construction.

Are Blue Engineering Bricks More Expensive Than Other Types?

Blue engineering bricks may be slightly more expensive than common bricks due to their high strength and durability. 


However, the cost can be offset by the longevity and durability of structures built with them, reducing maintenance and repair costs in the long run.

How Does Blue Engineering Brick Compare With Facing Brick?

Blue engineering bricks are known for their strength and durability while facing bricks are used mainly for their aesthetic appeal, available in a host of different colours. 

Engineering bricks have lower water absorption and higher frost resistance, making them more suitable for harsh environments than facing bricks.

What Is The Significance Of BS EN 771 In Relation To Bricks?

BS EN 771 is a European standard specifying the requirements for masonry units, including bricks. It ensures the quality, durability, and safety of the bricks.
