Engineering bricks are typically used underground for foundations, as damp-proof courses or in wet environments. If you're after an aesthetic brick please check out our range of facing bricks.
What Are Solid Blue Engineering Bricks?
Solid Blue Engineering Bricks are highly durable masonry units designed for demanding structural applications. These bricks are specifically chosen for their strength, ability to resist water penetration, and their excellent frost resistance. They are commonly used in situations where high performance is critical, particularly in below-ground and exposed settings.
The characteristic blue color of these bricks is a result of the specialized manufacturing process, where they are fired in a low-oxygen atmosphere to create a distinct finish. Classified as Class B, these bricks have a compressive strength of at least 75N/mm² and are engineered to meet stringent limits for water absorption.
Colour Variations: Although the typical colour is a smooth blue, slight variations in shade can occur depending on the specific firing conditions and the raw materials used. This is a normal characteristic of the manufacturing process and does not affect the performance or functionality of the brick.
Applications
- Below Ground Applications: Ideal for use in foundations and substructures, especially below the Damp Proof Course (DPC), where water resistance and strength are essential.
- Damp Proof Courses: Due to their low water absorption rate, these bricks are commonly used in DPC courses to prevent moisture from rising through walls.
- Wall Capping: Solid blue engineering bricks can be used as capping bricks to create a clean, weather-resistant finish at the top of walls, often incorporating creasing tiles for additional protection.
- Retaining Walls: Their strength and resistance to moisture make them an excellent choice for constructing retaining walls that are exposed to pressure and environmental elements.
- Manholes & Inspection Chambers: Their durability and resistance to chemicals make them ideal for underground drainage and utility structures, such as manholes and sewer systems.
- External Features: Solid blue engineering bricks are also used for creating robust external features, such as plinths and cappings, which require both weather resistance and structural strength.
Benefits
- Compressive Strength: With a minimum compressive strength of 75N/mm², these bricks are capable of bearing significant structural loads.
- Low Water Absorption: Their low porosity makes them resistant to moisture damage and frost, ensuring long-term durability even in challenging weather conditions.
- High Durability: Made from vitrified clay, these bricks are resistant to wear and tear, making them suitable for use in aggressive environments.
- Frost Resistance: Due to their low water absorption, these bricks are highly resistant to damage from freeze-thaw cycles, ensuring they maintain their structural integrity in colder climates.
- Chemical Resistance: Excellent resistance to the effects of sulfates and other chemicals often found in soils, making them ideal for ground contact applications.
- Consistent Manufacturing Quality: These bricks are produced to high standards, ensuring uniformity in performance and quality across all units.
Class B Engineering Bricks Meaning
Contrary to popular belief that Class A engineering bricks are always blue and Class B are invariably red, the contemporary market presents a different reality.
You can now find red Class A engineering bricks and blue Class B engineering bricks, broadening the available colour choices.
Unlike facing bricks, the selection of engineering bricks is driven by their physical attributes, not their appearance. Where aesthetic performance is a major consideration, consider using one of our many facing brick options.
A Class B brick stands out with its impressive compressive strength exceeding 75N/mm² and its water absorption staying below 7%.
