Why Choose Topaz Multi Stock?
Topaz Multi Stock is especially suited for projects where you want a bold, characterful brick that still retains consistency. Its multi-toned red hues help mask colour variation, giving façades visual richness without appearing patchy. The heavy texture adds a tactile quality and helps reduce glare in direct sunlight.
From a structural perspective, it offers solid fundamentals. The compressive strength of 12 N/mm² and F2 durability rating means it’s suitable for many external wall applications, provided you combine it with good detailing. With 15 % water absorption, careful design of cavity systems, damp proof courses, and flashings is essential to maintain moisture resilience. Its salts classification and stock brick construction further support long-term performance.
Frequently Asked Questions
Will the colour vary too much across a wall?
Some variation is expected—especially in multi-tone bricks. To maintain visual harmony, mix bricks from multiple packs during laying and avoid stacking similar tones in one area.
Is 15 % water absorption acceptable for external use?
Yes, 15 % is within acceptable bounds for stock facing bricks. But success relies on careful detailing: well-designed cavity walls, damp proof courses, proper flashings, and avoiding moisture bridges.
Can Topaz Multi Stock be used structurally / in loadbearing walls?
It can be used in many masonry applications. While 12 N/mm² isn’t extremely high, it’s adequate for standard walling loads. Always check your structural calculations, mortar choice, lintel support, and relevant building regulations for your specific design.
