Wienerberger Class B Red Clay Perforated Engineering Bricks 65mm

The Wienerberger Class B Red Clay Perforated Engineering Brick (65mm) is a strong and durable brick designed for structural applications requiring reliability and water resistance. Manufactured from high-quality clay, these engineering bricks provide excellent compressive strength while maintaining a clean, uniform red finish.

Specifications

• Brand: Wienerberger
• Type: Class B Perforated Engineering Brick
• Material: High-density fired clay
• Dimensions: 215mm (L) x 102.5mm (W) x 65mm (H)

Benefits

• Structural Strength: Suitable for demanding load-bearing and general engineering work.
• Water Resistant: Low absorption rate makes them ideal for below DPC (damp proof course) use.
• Durable Construction: Resistant to frost, weathering, and long-term wear.
• Consistent Finish: Smooth red surface provides a neat and professional look.
• Versatile Use: Ideal for both structural applications and aesthetic brickwork.

Common Applications

• Foundations and retaining walls
• Groundworks and below DPC installations
• Civil engineering projects (bridges, tunnels, sewers)
• General load-bearing and structural brickwork

What is the difference between Class A and Class B engineering bricks?
Class A bricks offer higher compressive strength (≥125N/mm²) and lower water absorption (≤4.5%), while Class B bricks (≥75N/mm², ≤7% absorption) provide strong, reliable performance for most structural applications at a lower cost.
