Commercial Push Pier Systems
Push Pier Systems are an effective method for stabilizing and/or lifting sinking or settling foundations.
Push Pier Systems utilize high-strength round steel tube and load transfer brackets to stabilize existing foundations.
Foundation brackets are secured against existing footings and pier sections are driven hydraulically through the foundation brackets and into the soil below using the combined structural weight and any contributory soil load as resistance.
Pier sections are continuously driven until a suitable load bearing stratum is encountered. At that point, the structure either begins to lift or the target pressure/load is achieved.
The weight of the structure is then transferred from the unstable soil, to the foundation brackets, through the piers, and to firm load bearing soil or bedrock.
ADVANTAGES
- End bearing pier that does not rely on skin friction for capacity
- Portable equipment allows for installation in areas of limited access
- Piers are individually load-tested during installation
- System design allows for lifting of settled structures
- Factors of safety typically range from 1.5 to 3
- Galvanized pier sections for added corrosion protection
