One of the beautiful qualities of bricks
is their ability to be reused and repurposed.

Bricks are a familiar feature in the paths and decorative walls and edgings of many New Zealand gardens.

New brick units generally have a higher moisture content that settles over time. This can affect a bricks ability to handle loads that reduce the unit’s size. The reduction of moisture from the brick may also affect mortar bonding.

Before reusing bricks or blocks NZS 4210:2001 (section requires testing of compression strengths and 7-day mortar-to-mortar bond strengths.

This should be undertaken even if a building consent is not required as part of confirming building code performance requirements will be met.

Master Brick & Blocklayers does not recommend reusing bricks if you are unsure whether they have come from the same veneer as this may complicate testing.
