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 at least 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,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 at least 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 a part of the second section bulk thickness fits in the at least one aperture of the at least one first section.Filter including the support and drainage material, and methods of use are also disclosed.
