Most Keystone walls can be built directly on 4-6″ (100-150mm) of well compacted granular base. However, there may be occasion to consider the use of a concrete leveling pad. EXAMPLE: Applications in or near water, a taller wall built on soft sub-soils, or a wall that is very long and by using a concrete footing, the contractor can speed up the installation process.
