FIELD: construction engineering.
SUBSTANCE: invention relates to construction engineering, in particular to a synthetic multilayer floor covering. The coating comprises floor panels, each of which comprises at least the first and second edges with the first and second connecting profiles. The first connecting profile of the first floor panel and/or the second connecting profile of the second floor panel are deformed when the connecting profiles are engaged with each other. The deformation contains a component that continues to hold when the connecting profiles remain engaged. The remaining deformation causes stress within the coupling profiles made of a viscoelastic material that can significantly reduce tension. At ambient temperature and pressure, the voltage in the first and/or second connector profile decreases by at least 40% within 12 hours of the engagement of the connecting profiles.
EFFECT: increased operational reliability.
