Frequently Asked Questions
Will the terracotta colour appear consistent across a wall?
Some variation is natural, especially with terracotta shades. To achieve a balanced look, mix bricks from multiple packs during installation and avoid placing bricks from the same pack consecutively.
Is ? 15 % water absorption acceptable for exterior use?
Yes — 15 % is within acceptable bounds for facing bricks. That said, durable performance depends heavily on correct detailing, including cavity design, damp proof courses, and proper flashings.
Can this brick be used for structural or loadbearing walls?
Yes. With a compressive strength of 13 N/mm², the brick can be used in many masonry applications. For heavier structural loads or critical elements, always verify load calculations, mortar grade, support design, and compliance with local building regulations.
