What are interlock bricks?
Interlock bricks are building bricks with shaped faces that fit into the neighbouring bricks, so each course locks onto the one below. They are used to build walls, from boundary walls to houses and larger buildings.
They are not the same as interlock paving blocks, which are laid flat to pave the ground. For those, see our guide to paving blocks.

How many interlock bricks do you need?
Multiply the wall area in square feet by the pieces per square foot for your brick. For example, a boundary wall 50 feet long and 6 feet high is 300 square feet. In our Interlock Bricks, at 2.25 pieces per square foot, it takes 675 bricks. We confirm the exact quantity for your building before you order.
