2. Landscape fabric - Wikipedia

   en.wikipedia.org/wiki/Landscape_fabric

   Landscape fabric (a.k.a., weed barrier) is a textile material used to control weeds by inhibiting their exposure to sunlight. The fabric is normally placed around desirable plants, covering areas where other growth is unwanted. The fabric itself can be made from synthetic or organic materials, sometimes from recycled sources.

3. Geotextile - Wikipedia

   en.wikipedia.org/wiki/Geotextile

   Typically crafted from polypropylene or polyester, geotextile fabrics are available in two primary forms: woven, which resembles traditional mail bag sacking, and nonwoven, which resembles felt. Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are durable and are able to soften ...

4. Cleavage (geology) - Wikipedia

   en.wikipedia.org/wiki/Cleavage_(geology)

   Cleavage is a type of rock foliation, a fabric element that describes the way planar features develop in a rock. Foliation is separated into two groups: primary and secondary. Primary deals with igneous and sedimentary rocks, while secondary deals with rocks that undergo metamorphism as a result of deformation. Cleavage is a type of secondary ...

   Foliation (geology) Gneiss, a foliated metamorphic rock. Quartzite, a non-foliated metamorphic rock. Foliation in geology refers to repetitive layering in metamorphic rocks. [ 1] Each layer can be as thin as a sheet of paper, or over a meter in thickness. [ 1] The word comes from the Latin folium, meaning "leaf", and refers to the sheet-like ...

6. Retaining wall - Wikipedia

   en.wikipedia.org/wiki/Retaining_wall

   Definition. A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. [ 1]
