Description & Usage Notes

The K201 65P engineering brick is made by extrusion and features perforations to reduce weight while maintaining strong structural integrity. With low water absorption (? 7%) and high compressive strength (? 75 N/mm²), it’s well-suited for structural and moisture-critical applications such as foundations, cavity walls, sewers, or retaining structures. While it can be used above ground, its primary design is for performance over appearance. Using it for visible facades may show variation in shade or finish. To maximize longevity, incorporate optimal detailing like correct mortar, drainage, and flashing. Because this is an engineering brick, mix from multiple packs during installation to reduce visual variation. Requesting samples or close-up images before bulk orders helps confirm you’re happy with the tone and texture.

FAQs

What does “perforated” mean in this context?

Perforated means the brick has vertical holes (cores) which reduce weight and material without significantly compromising strength.

Is ? 7% water absorption adequate for engineering bricks?

Yes — it’s within the standard for Class B engineering bricks, helping to resist moisture ingress in demanding conditions.

Can I use this brick where appearance matters?

Yes, you can, but be aware that engineering bricks are designed for performance, not appearance. Expect variation in colour and texture; if aesthetics are critical, a facing brick is usually better

Roof Tiles & Fittings:
