Disclosed herein are a module, system and technique to enhance end bearing stiffness of pile/drilled shafts. In particular, methods, systems and loading modules which account for tip resistance in overall pile/shaft capacity are provided which increase the stiffness of the bearing soil. The techniques utilize a mechanical system to preload the soil under the shaft tip, thus allowing the users to confidently account for the gained resistance at an acceptable level of movement. Each shaft/pile is preloaded during construction to verify its load carrying capability.
