Photo Album: The Missions at Rio Vista Apartment Buildings
During renovations at a large San Diego apartment complex, Saber crews discovered that several buildings had settled severely. To correct the problem, they had to excavate along the walls to expose the concrete footing and attach heavy‑duty push‑pier brackets. This project required 25 interior piers and 15 exterior piers; the steel tubes were hydraulically driven through the brackets until they reached competent soil or bedrock. Once the piers were seated, crews connected hoses and hydraulic gauges to each bracket. The piers were then pressurized simultaneously to raise the structure back toward its original elevation. After the lift, the trenches were backfilled and the pier tops were left buried, permanently transferring the building’s weight into stable ground. A panoramic photo shows the long row of piers supporting the apartment building, while a close‑up reveals how each bracket will remain at the footing and be concealed after backfilling. With the installation complete, the complex was leveled and the risks associated with uneven settlement were eliminated.
Piers in place and hoses attached ready for the lift.
Soils were removed from the area of were the piers were placed. A heavy duty steel bracket was installed below and against the foundation's footing. Steel pier sections were then hydraulically driven through the brackets to bedrock, or a stable soil layer. Next, the weight of the structure will be transferred through the piers to competent soil below, and the lift will be attempted to bring the structure back toward its original position. Once the stabilization and lift of the structure are complete, the soil will be backfilled and the structure will be permanently stabilized in its new position.
Piers are attached to hoses and ready for the lift.

This is will remain as a permanent fixture at the foundation's footing, once the job is complete, it will be covered with the soil that is used to back fill the exposed locations.
