FIELD: bases and foundations.
SUBSTANCE: invention relates to protection of wooden piles or wooden elements of piles in conditions of heaving soils and can be used for production of wooden pile bases of power transmission lines (PTL). Method of treating wooden pile base with anti-heaving coating. A polymer anti-heaving waterproof coating including a polymer heat shrink layer is applied on the pre-cleaned and levelled surface of the wooden pile base. Layers of anticorrosion primer with anti-rot properties and hot-melt adhesive are successively applied between the surface of the wooden pile base and the polymer heat shrink layer. Layer of anticorrosion primer is made with thickness of not less than 25 mcm, and length of polymer anti-heaving waterproof coating is equal to depth of seasonal freezing of soil.
EFFECT: increased service life of wooden pile bases in heaving soils.
