Abstract: The invention relates to a surface coverings system for a surface such as a roof, a floor or another substantially flat surface subjected to water and needs drainage, and methods for preparing such a system. The surface covering system comprises a rectangular plate with a mark marking a highest point, a substantially flat lower surface and an upper surface with a first slope facing from the mark towards a second mark provided in connection to the outer edge of the plate. The first slope is circular and has a linear radial inclination (?) facing from the mark towards essentially all points on the rectangular plate. The slope forms an elevation in the plate forming at least a part of a cone or blunt cone with the tip of the cone defined by the mark with the lowest point(s) of the upper surface of the disc defined by the second mark.

Abstract: A cutting device for cutting a material includes: a frame structure arranged to be pivoted around a pivot axis, wherein the frame structure includes at least two essentially parallelly arranged frame portions arranged at a distance (d) from each other along a first axis (x), wherein a cutting wire is arranged between the frame portions and connected to the respective frame portions, wherein the material is cut and formed by the cutting wire during a pivoting relative movement between the frame structure and the material around a pivot axis (p).

Abstract: The invention relates to a surface covering system intended for a surface in the form of a wet room floor, a roof or another substantially flat, delimited surface which is exposed to water and needs drainage, and to methods for preparing such a system. The surface covering system comprises at least one plate with a mark showing a drainage point and a substantially flat lower surface and an upper surface with a first decline towards the mark. The invention is characterized by that the first decline is circular and has a radial slope (?) directed towards the mark from every point on the at least one plate. The decline creates a cavity in the plate in the shape of at least a part of a blunt virtual cone with the apex of the cone directed towards the mark, achieving a modular surface covering system with an even circular decline.
