Two methods are used to support earth pressure on a basement wall. In one of these, the basement wall supports the earth pressure and is commonly used where the site is much larger than the building's footprint to allow open excavations. The second method is used on a tight site, where the building's footprint covers the entire site or most of it. What type of excavation support system is used in
the second method?
What will be an ideal response?
In this method, the excavation support system supports the entire earth pressure so that the basement wall has no earth pressure imposed on it.
