FIELD: construction.
SUBSTANCE: invention relates to the construction and repair of concrete structures, cable, sewerage, gas wells and reinforced concrete structures, collectors and tunnels, namely, to the sealing of the utility penetrations. Way of sealing utility penetrations consists in pumping water out of the well, if any. Walls of the well are cleaned in places where the pipeline passes through holes in the walls of the well. Waterproofing compound is applied. Holes in the walls of the well at utility penetrations of the well are sealed by winding the self-expanding tow on the pipeline.
EFFECT: technical result consists in reducing the labor intensity and time of construction and repair work, improving the quality of sealing of utility penetrations in the concrete structures under operation and construction.
