Created page with "The design foundation lengths required to resist uplift against ground heave and structural uplift can be calculated from the soil side resistance below the frost zone. The depth of frost penetration and adfreeze bond strength is used to determine the ground heave portion of the load to be resisted. Published adfreeze values generally range from 10 psi to 20 psi, with some silts ranging as high as 45 psi. Many foundations have been installed according to the Tsytovic..."
