1. A floor structure comprising:
a universal membrane configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor, the universal membrane comprising:
a base layer forming a planar surface;
a plurality of studs projecting from the base layer; and
a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs, each sidewall of the plurality of sidewalls forming a perimeter of a pocket, the base layer forming a bottom wall of the pocket, wherein:
a first portion of the universal membrane is configured to be separated from a second portion of the universal membrane;
the first and second portions of the universal membrane are configured to be coupled to one another by inserting the plurality of studs on one of the first and second portions of the universal membrane into the pockets formed by the plurality of sidewalls on the other one of the first and second portions of the universal membrane;
the first portion of the universal membrane forms a base membrane configured to be placed on the subfloor; and
the second portion of the universal membrane forms a cover membrane configured to cover the base membrane and to support the floor tiles.
