Expansion joint profile system

A floor covering, comprising:

• a profile (1) comprising a first profile element (3) made of a first material and having an L-shaped cross-section, extending in a longitudinal direction (L) and having a first support leg (5) provided for bearing on a substrate (18) and a first abutment leg (6) connected to one of the longitudinal edges of the support leg (5) and projecting upwardly therefrom, a second profile element (4) made of said first material and having a second abutment leg (6) which is formed to correspond to the first abutment leg (6) and extends parallel to the first abutment leg (6), and a connection element (9) which is made of a second material having a higher elasticity than the first material, the second material being a soft-set silicone or elastic material, which is resistant to fungi and bacteria, wherein the connection element (9) is formed in a ridge-like manner, extends in the longitudinal direction between the two profile elements (3, 4), connects them to one another in the lower region allowing them to move elastically relative to one another and, together with the two abutment legs (6), forms an insertion opening (10) which is open at the top and extends in the longitudinal direction (L),
• at least two tiles or stone slabs (16), one each of which is installed atop a support leg (5) with a portion of end faces of the tiles or stone slabs (16) in contact with the abutment legs (6) and another portion of end faces of the tiles or stone slabs extending above the abutment legs (6);
• and
• a sealing element (11) made of a third material having a higher elasticity than said first material, wherein the sealing element (11) extends in the longitudinal direction (L), is formed in a T-shaped cross-section with a downwardly projecting insertion leg (12) designed for insertion into the insertion opening (10) and with two laterally projecting compression legs (13), wherein the compression legs (13), when the insertion leg (12) is disposed in the insertion opening (10), project outwardly above the abutment legs (6), respectively, the compression legs pressing against the portion of the end faces of the tile or stone slabs (16) extending above the abutment legs (6).
