Consider the soil.
Before you start building your limestone retaining wall, you must check the type of soil you have. In building a limestone retaining wall you have to ensure that it has a proper foundation since there are areas in Perth locality that have loose soil which is not suitable to lay retaining wall without strong foundation.

Installing proper irrigation will ensure that pressure from water does not end up damaging your retaining wall.
