Rat Trap Bond
Rat trap bond is a brick masonry method of wall construction, in which bricks are placed in vertical position instead of conventional horizontal position and thus creating a cavity (hollow space) within the wall.
ADVANTAGES:
1.Requires approximately 25% less bricks and 40% less mortar than traditional masonry
2.Reduced material requirement results in considerable cost saving
3.Strength of wall is not compromised, it remains same as traditional masonry wall.
4.Cavity induced in wall provides better thermal insulation, resulting in cooler interiors during summer and warmer interiors during winter.
5.All vertical and horizontal reinforced bands, lintels (for standard size openings), electrical conduits are hidden inside wall, resulting in better aesthetic appearance without plastering (exposed brickwork).
