Abstract
An uncoupling mat includes a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side. The annular cavities on the bottom side each define a recess on the first side. The indentations have a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations. A plurality of weakening zones each extends between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones.

An uncoupling mat, comprising:
- a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side, the annular cavities on the bottom side each defining a recess in a middle thereof on the first side,
- the indentations having a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations,
- a plurality of weakening zones, each extending between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones,
- wherein at least some of a first group of weakening zones extend parallel to one another, said parallel weakening zones extending transversely to a longitudinal direction of the uncoupling mat, and
- wherein at least some of a second group of weakening zones extend parallel to one another, the second group of parallel weakening zones crossing the first group of parallel weakening zones.

- wherein at least some of a second group of weakening zones extend parallel to one another, the second group of parallel weakening zones crossing the first group of parallel weakening zones;
- and wherein
- the weakening zones are formed in bottom portions of the indentations such that the indentations extend beneath a heating cable when a heating cable is held within the indentations.
