When repairing the foundation of a house it is important to choose a method that will be last, but also economical.
The premise of a concrete pressed piling is six inch diameter concrete cylinders which are pressed under intense pressure using a hydraulic press and being able to withstand over 50,000 pounds of applied load. These concrete cylinders can be pushed as deep as 50 feet into the ground depending on the geological formation, and can provide a solid foundation for many structure types.
The first cylinder is pressed vertically, and additional cylinders are stacked flush as the pier is driven to bedrock or refusal. Refusal means the amount of friction built up around the piling requires greater than the applied force from the hydraulic piston to reach any further depth, and further pressure from the piston could damage the foundation.
After this, the home is raised by the hydraulic jacks, and once this has been done, the piers are shimmed off with steel spacers before the jacks are removed. The holes are then backfilled and tamped down, concrete is patched, and landscaping is put back in place.
There are multiple reasons why you should choose this foundation repair method for your home. The main reason is the economic value of concrete pressed piling. This method of repairing a foundation is cost-effective and also offers long-term stability in the right soil conditions.

Stress to the foundation of the building can also occur during this process and this may need further work. This,in turn, will cost you a little more money as well as time.
