Document Type and Number:
WIPO Patent Application WO/2024/003106
Kind Code:
A3
Abstract:
The invention relates to a plastics geo-mat, comprising an upper cover layer, a lower cover layer, and a middle filling layer, which is disposed between the upper cover layer and the lower cover layer and is composed of a filling layer material comprising a material capable of swelling. The invention is characterized in that the upper cover layer and/or the lower cover layer consists of or comprises a biodegradable material; the peeling resistance at a predefined time after the start of the biodegradation process is characterized by a residual degree of peeling resistance, which is formed by the square of a quotient of a reduced peeling resistance which the upper and lower cover layers and the connecting structure have at the predefined time and an initial peeling resistance which the upper and lower cover layers and the connecting structure have before the start of a biodegradation process.
