Why Choose Chartham Multi Stock?
Chartham Multi Stock is a great choice when you want a brick that feels classic and enduring. Its red / multi tones provide subtle variation that avoids a flat look, while the light texture brings softness and character to façades. The stock (pressed) method gives a balanced, refined surface that fits both modern and traditional designs.
Technically, it handles the essentials well. With 13 N/mm² compressive strength and F2 durability, it supports external walling in typical UK climates. Its ? 15 % water absorption is moderate — so proper detailing (cavity design, damp proof courses, flashings) is critical for long-term performance. The brick’s fire rating (A1) and salts classification (S2) help ensure it meets safety and durability expectations.
Frequently Asked Questions
Will the red / multi tones appear uneven?
Some variation is inherent in multi-tone bricks. To maintain a consistent look, blend bricks from multiple packs while laying and distribute tones evenly across the elevation.
Is ? 15 % water absorption acceptable for external use?
Yes — 15 % is within acceptable limits for many facing bricks. But long-term success depends heavily on quality detailing, such as well-designed cavities, damp proof courses, and flashing to manage moisture.
Can Chartham Multi Stock be used structurally?
Yes. While 13 N/mm² is not extremely high, it is sufficient for many masonry applications. For more demanding structural requirements, always verify with your structural design, mortar class, and local building regulations.
