3. Decrease the tallness of the retained material by regrading. Here and there changing the landscape configuration is an acceptable strategy to an allowable utmost based on the wall plan.
4. Transfer a portion of the shear power at the location where the wall interfaces with the ground. This increases the overall quality of the wall. There are two strategies:

Tiebacks add solidarity to retaining walls. Adding a gravel bed behind and beneath the wall or perforated drain tiles coating the base of the wall can substantially improve drainage. This lessens trapped water and freezing behind the wall that can apply pressure, causing failure.
The most ideal way to forestall a retaining wall failure is to plan the wall for the site conditions, taking into account the terrain, climate, and soil properties, with the goal that the wall will have the option to play out its capacity safely. Reconstructing and rectifying the failures is always an alternative. Be that as it may, it may be exorbitant and require excavation.
