Sloped concrete is concrete that is used in the production of slope in roof structures. This can be retrofitted as concrete to existing load-bearing reinforced concrete ceilings or produced in the form of prefabricated elements.
Sloped concrete can be used on flat roofs below the insulation level if insulation or insulation boards without slope are desired. In this case, the sloped concrete creates the slope for the roof drainage. Insulation, roof waterproofing and upper roof structure are then applied to the concrete layer.
Depending on the application and stress, sloped concrete can also be produced, for example, as exposed concrete for the drainage of balconies and loggias.
case of a concrete surface, the condition of the composite joint between the concrete layers is of particular importance, as it must be free of contamination by foreign substances. (pre-wetting required) The bond can also be created using dowels or reinforcement connections. If this is not possible, the surface of the old concrete must be treated using mechanical or alternative roughening methods before the concrete is poured.

reinforced concrete or precast concrete elements with a slope can be used.
