Frequently Asked Questions
Can I use this for red bricks?
No, this is specifically optimized for AAC/CLC blocks which are larger (600mm length). For red bricks or fly ash bricks, please use our 'Brick Calculator'.
Does it account for breakage?
The block count is a mathematical estimate. We recommend buying 3-5% extra blocks to account for onsite handling breakage and cutting wastage.
