When should I Use Push Piers Instead of Helical Piers?

When determining the appropriate foundation repair solution, push piers are typically used in specific scenarios where their unique mechanical principles offer an advantage over helical piers.

You should use push piers when:

• Reaching deep bearing strata: They are an ideal solution when a firm bearing layer, such as bedrock or very dense soil, is reachable at a predictable depth.
• Supporting heavy loads: They are frequently preferred for heavily loaded commercial foundations or projects requiring substantial load transfer that utilizes the structure’s own weight.
• Working in cohesive clay soils: The installation method works exceptionally well in these soils, where friction capacity along the pier shaft provides additional support.
• Seeking minimal settlement: Because they are driven to refusal against competent strata, they provide robust support with very little risk of future movement.

While helical piers are often preferred for lighter residential loads or projects requiring fast installation with low vibration, the choice ultimately depends on site-specific geotechnical data. It is recommended to consult a structural engineer to perform a soil analysis and determine which system meets the necessary load-bearing requirements.
