<p>Method for forming a ground- covering layer (1), comprising the steps of providing a sheet (2); forming a number of substantially parallel folds (3) in the sheet; and urging toward each other and connecting to each other adjacent folds at different locationsm wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side. Ground- covering layer (1), comprising a sheet (2) with a number of substantially parallel folds (3), which folds are connected at different locations to adjacent folds, wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side.</p> |
