Rat-trap bond is a type of brick masonry used in wall construction. It is named so because the arrangement of bricks in this bond resembles the shape of a rat trap. The bond consists of alternate courses of headers (bricks laid flat) and stretchers (bricks laid end-to-end) with the headers centered over the joints between the stretchers in the course below.

This bond provides strength and stability to the wall, and it is commonly used in load-bearing walls where the weight of the structure above must be supported. It is also used in walls that require added insulation, as the spaces created between the headers and stretchers can be filled with insulation material.

In rat-trap bond, each header is laid over the center of two stretchers in the course below, and it is bonding into the two stretchers. This interlocking pattern results in a strong bond, making it an ideal choice for load-bearing walls. The bond also provides good stability to the wall by distributing the weight evenly across the wall.

Overall, rat-trap bond is a durable and cost-effective method of wall construction that provides strength and stability to the structure.
