Choosing masonry blocks for the right application

Blocks that look alike may behave differently. Dimensional tolerance, compressive strength, density, moisture absorption and acoustic or thermal properties should match the intended wall application.

Context and objectives

A unit price comparison misses installation costs. Waste, mortar or adhesive, labour speed, bracing and on-site handling all affect the completed wall cost. Check project drawings and local codes before approving a product.

Action checklist

• Define whether the wall is external, internal or a partition.
• Request relevant technical data and test documentation.
• Compare installed cost per square metre of wall.
• Check connections, bracing and service penetrations.

Key takeaway

Select against project performance requirements, not product marketing alone.
