Constructed in two parts, our Borough Wharf PestBrick has been expertly designed to replace bricks during brick laying. Available in a range of colours, our Borough Wharf PestBrick features a strong, durable cover that slides into place on the air brick itself. It is then mortared into the wall just like a traditional air brick! Boasting unique interlocking spacers that provide the required distance between the air bricks to continue the cement line, the air brick can be stitched in with the brickwork just like a normal brick for a seamless installation.
