- Depth required can be determined by the load of the structure being raised
- Soils are tested by driving the pilings into the soils
- Concrete is tested under the load it is required to support
- Pre-cured/tested concrete enables immediate leveling of the structure — most jobs are completed in 2-3 days
- Site cleanliness and 2-3 day job time save destruction of valuable vegetation

- Proper installation cannot be verified
- Alignment is impossible given below-ground obstructions
- No reinforcement to prevent shifting of cylinders (vertical or horizontal) after work is completed and soil moisture changes
- City cannot inspect due to time requirement — therefore, inspectors must be paid by the company performing the work or not at all
