Abstract: The invention relates to a cutter and a method for making a barrier screen in a dike body for preventing soil particles. The cutter comprises: —a part that is oriented vertically when in use and that comprises a supply device for supplying to soil material of said dike body a binder for binding soil material that has been cut by said cutter, said vertically oriented part at a lower portion thereof being provided with chisels for cutting said soil material during a downward movement of said cutter; —as well as a part that is horizontally oriented when in use and that extends at both sides of said vertical part and wherein said parts that are provided at both sides comprise cylinders that are rotatable about a horizontal rotation axis and wherein said cylinders are provided with ground cultivating members for mixing soil material that has been machined by said chisels and said ground cultivating members.

Abstract: The invention relates to a method for making a barrier screen in a dike body for preventing transport of soil particles, said barrier screen being positioned substantially standing and extending in a longitudinal direction of said dike body, wherein in said method said barrier screen is obtained by mechanically mixing soil that is already present in said dike body with a binder. The method is characterized in that it comprises the step of displacing the chain cutter along the trajectory of the barrier screen to be made through the dike body and mixing the soil present and the binder as well as inserting a cloth into the mixed soil.
