Beschreibung
Zusammenfassung:	A support and drainage material comprising a foldable element allowing fluid flow through, the element comprising: at least one first section comprising a mesh or a non-woven fabric having a first end and a second end, a first side and a second side, a first major surface and a second major surface, and a first section bulk between the first major surface and the second major surface, the first section bulk having a thickness extending from the first end to a portion of the second end; wherein the at least one first section further comprises at least one first section aperture extending a length of about 25% to about 75% a distance between the first end and the second end, and extending a length of about 2% to about 100% a distance between the first side and the second side; and/or at least one second section comprising a mesh or a non-woven fabric having a first end and a second end, a first side and a second side, a first major surface and a second major surface, and a second section bulk between the first major surface and the second major surface, the second section bulk having a thickness extending from the first end to a portion of the second end;wherein the at least one second section further comprises at least one second section aperture extending a length of about 25% to about 75% a distance between the first end and the second end, and extending a length of about 2% to about 100% a distance between the first side and the second side; wherein, when the foldable element is folded, a part of the first section bulk thickness fits in the at least one aperture of the at least one second section, and/or a part of the second section bulk thickness fits in the at least one aperture of the at least one first section.Filter including this material and methods of use.
