Breast wall  are types of protection walls used in civil engineering  works. Breast  are used to  protect  the fresh cut of earth. There  is always a confusion between  retaining wall and breast wall. The Breast  wall is built on the  hill side  of a  Road as it  protects the natural cut slope of Road. Retaining wall  is built on the valley side  of road. Breast has a small range of height nearly from 2 to 3 meters and retaining wall can  have more height.  Breast   wall  help  in  protecting  the cut  slope from further Erosion.  Both breast walls and Retaining walls  are used in hilly road constructions  having steep slopes and it can  also be used  in Embankment to protect them from erosion. Breast wall can be constructed in plain  Concrete or in Stone Masonry. In these photos we  can see Breast walls being constructed in Stone masonry ...

  GABION CRATES OR WIRE CRATE ARE ALSO USED AS A PROTECTION WORK FOR PROTECTING LARGE MASSES OF EARTH. THEY CAN BE USED AS RETAINING AS WELL AS BREAST WALL. WIRE CRATES ARE AVAILABLE IN DIFFERENT SIZES AS PER THE SITE REQUIREMENTS. WIRE CRATES ARE MOSTLY ZINC COATED SO THAT RUST DOESNOT AFFECT THEM. WIRE CRATES ARE EASY TO LAY AND EFFECTIVE IN WORK. STONES ARE PACKED IN LAYERS IN WIRE CRATES AND WHICH IS EVENTUALLY LOCKED BHY JOINING WIRES MAKING IT AS A COMPLETE STRUCTURE.

BREAST walls are provided to hold in place  mass of earth or excavation. They provide stability to natural slope. In these photos  walls are being provided in dry  stone masonry with Random Rubble masonry in 1:6  mix cement sand mortar in vertical bands and concrete in bottom. At some places breast wall in concrete are also provided with proper weep holes to drainage out the water.
