The concrete floor for an apartment terrace has underside heat insulation covered by a water catchment sloping membrane. To prevent the membrane (5) from forming cracks or other defects, it is made of corrosion-protected thin metal plate. To prevent plastic deformation of the plate material and the forming of deepened sections where water might accumulate, the membrane has a bent part (17) at the terracee floor inner part (18) which supports a sloping closure (4) in the floor (2). |
