Breast Wall


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 .

 


Breast walls have slope  on front side just to make  them more stable. Breast walls are very important in stopping  soil from  continuous erosion.






In this  photo the sides of Walls  stone Masonry  are constructed with sand cement mortar. In between  Random  rubble  masonry of cement mortar dry stone masonry is done.




                                               

Weep holes  are being used in Concrete  breast walls. These weep holes act as filter media  to prevent  breast wall from being  damaged  by water pressure.
