Abstract: The invention relates to a decoupling mat (1) with a continuous plastic layer (2), for example one fabricated via deep drawing, comprising elongated, rib-like formations (3) on a first broadside (B1), wherein the formations (3) simultaneously form groove-like recesses (5) on a second broadside (B2) lying opposite the first broadside (B1). In order to achieve a solution advantageous for use, emphasis is placed on having the formations (3) be bordered in their longitudinal extension (1) by sections (9) of a reduced height (h?) and/or width (c?), which simultaneously also form partial areas (10) of less depth (s?) and/or width (d?) bordered relative to the recesses (5). In addition, the invention relates to a floor structure, in particular in a building with a decoupling mat (1).
