Typical Steps in a Piering Installation
- A 3'x4' excavation is made adjacent to foundation and approximately 10" below the grade beam.
- Soil is scrapped from the footing bottom and the foundation is chipped smooth to ensure proper fit of support bracket.
- Brackets and hydraulics are installed and a guide sleeve is advanced through the support bracket.
- Starter and pier sections are advanced to refusal at an average penetrating power of 50,000 pounds of total driving force.
- The last pier section is cut approximately 5" above the support bracket and a fastening plate is installed on top of the pier column.
- The hydraulics are reconnected and are operated sequentially to raise the structure.
- When the structure has been raised to the desired height the fastening plates and support bracket are permanently attached to the pier column.
- When the structure is secure, depth, pressure and elevation readings are recorded for each pier.
- The excavated soil is replaced and compacted.
- Shrubbery and concrete removed for the pier installation is replaced.
