The efficiency of the heat-shrinkable, radiation-modified polyolefin membranes to reduce the force of pile foundation with freezing freezes seasonally soils. An important factor for the calculation of shear forces heaving pile in contact with the cement-sand mixture. Shown that the use of pile casings production UZPT "Mayak" reduces power freezing steel piles with model cement-sand mortar of 2.3 - 3.3 times as compared with uncoated metal pile.
