Pull our resistance of the concrete pile

[KevinNZ]

How do I work out the pull out load for concrete pile?
Soil pressure and friction give a high load. Seems there must be somthing else going on.

Pullout resistences can be very high.

However, one thing you need to check is that the soil weight in the pull-out cone is not controlling the design. Additionally, an approriate factor of safety needs to be applied.
