Definitions

• the invention relates to a formwork sheet with improved slip resistance on the basis of a waterproof finished spunbonded fabric, a process for its production, and the use of the waterproofed spunbonded fabric as a formwork sheet.
• the invention has for its object to provide a formwork sheet that does not require a fine fleece and that offers high slip resistance and thus a high level of safety. Furthermore, the invention provides a formwork sheet that can be produced in a simple manner, since the previous bitumen embossing step at the roofing sheet manufacturer is no longer necessary, since it is easy to install because low end surface weights can be worked and which is characterized by a high tear resistance and nail tear resistance. For example, nail pull-out strengths of 60 - 220 N (measured according to the UEATC test method) can be achieved.
• the invention relates to a formwork sheet which essentially consists of a solidified spun-bonded nonwoven web made of filaments made of organic fiber-forming material and coated with an embossed weave pattern, the formwork sheet having a structure in the form of a weave pattern on at least one surface, preferably on one surface has to increase the slip resistance.
• a “structure in the form of a weaving pattern” is to be understood as a structure that can also be found in fabrics. This structure is created by embossing during the production of the spunbonded fabric and is retained on the formwork sheet even after it has been coated with the coating agent.
• Usual weaving patterns can be used, such as patterns in the form of the satin weave, in the form of the twill weave and in particular in the form of the plain weave.
• the depth of this pattern in the formwork sheet that is to say the difference between the highest elevations and the deepest adjacent depressions, is selected so that there is a sufficient degree of slip resistance. Typical values for the depth of a weaving pattern are in the range from 0.05 to 0.3 mm.
• the formwork sheet has a woven pattern in the form of a plain weave with a depth of about 0.2 mm.
