ABSTRACT:
Improved flooring is disclosed that is formed by concrete slabs (1) with several parallel ribs (11) on the upper surface, between which there are longitudinal channels (12) connected with a main channel (2) laid transversally, in relation with one of the ends of the concrete slabs (1), and which ends in an outside connection (3). The ribs (11) have a thickened part (13) on the upper edge with an inner hole (15) for the circulation of hot water. Between the thickened parts (13) there are some grooves (15). The flooring is manufactured on site or by means of prefabricated slabs.
