Why Choose Caldera Red Multi?
Caldera Red Multi stands out through its balanced “multi” red tones—enough variation to avoid flatness, but not so much as to look inconsistent. Its light texture adds visual interest without overpowering, making it versatile across styles.
On the technical side, it’s dependable. With a compressive strength of 30 N/mm² and F2 durability, it holds up in exposed environments. The ? 15 % water absorption is moderate—so, careful detailing like adequate cavity design, damp proofing, and flashings is important for long-term performance. Its fire safety and salts classification align with modern building requirements.
Frequently Asked Questions
Will the red tones appear patchy across a large wall?
A little variation is natural and part of the brick’s charm. To reduce the risk of visually disruptive banding, mix bricks from several packs during laying and distribute tones evenly throughout the facade.
Is ? 15 % water absorption safe for UK external walls?
Yes — it's within acceptable limits for facing bricks. However, good detailing (cavities, DPCs, flashings, and proper moisture management) is essential to maintain long-term resilience.
Can Caldera Red Multi be used structurally or in loadbearing walls?
Yes. With a compressive strength of **30 N/mm²**, this brick is strong enough for many structural masonry applications. As always, verify load demands, mortar selection, support design, and compliance with building regulations for your specific project.
