Sports flooring in tile or plank form

Abstract

A sports flooring in the form of a tile or plank with free installation and including coupling with an adjacent tile or plank. The flooring includes successively, from top to bottom, and bonded together: a surface layer including at least one flexible layer with a thickness between 0.3 mm and 1 mm and a compression modulus between 10 MPa and 100 MPa; a rigid intermediate layer with a thickness between 3.5 mm and 7 mm and a flexural modulus between 1000 MPa and 10,000 MPa, and a compression modulus between 35 MPa and 300 MPa; a shock-absorbing underlayer with a thickness greater than 3 mm, typically between 3 mm and 10 mm, and preferably between 5 mm and 10 mm, and a compression modulus between 0.5 MPa and 15 MPa.
