A soil reinforcement membrane that promotes grass, plant, and vegetation growth in a variety of temperatures and geographic locations and increases water retention. The soil reinforcement membrane is flexible enough to be placed on a variety of landscapes and promotes growth in a variety of soils. The soil reinforcement membrane consists of an upper layer and a lower layer with a cultivating compound dispersed uniformly between the two layers.

A natural invasion promoting method that is environmentally friendly, easy to carry out, can cope with a wide range of areas and inclined surfaces, achieves efficient natural invasion, and can satisfactorily promote greening on a soil surface of interest, and a spraying material used in the method are provided. A natural invasion promoting method including: spraying a spraying material containing live algae on a soil surface; breeding the live algae; and also directly or indirectly catching flying seeds or spores by a tacky substance secreted on surfaces of the live algae or a catching structure composed of the live algae to promote greening on the soil surface.

A water-permeable woven geotextile fabric for providing soil reinforcement and/or stabilization, for example as an underlayment in road construction, utilizes a series of round warp fibers, in combination with a series of flat warp fibers, across the width of the fabric to increase water flow while still providing desired filtration. In particular, the round warp fibers form angles that allow greater amounts of water to pass through the fabric. In addition, using both round and flat warp fibers results in increased roughness of the fabric surface, which makes the fabric more resistant to being pulled out of the soil when pulled on. Furthermore, one or more of the round and/or flat warp fibers can include a color selected for high visibility to the human eye in daylight conditions.

A silt barrier support system broadly comprising a number of vertically extending posts, a number of silt barrier attachment devices, a number of end silt barrier attachment devices, and an inward silt barrier attachment device. The silt barrier attachment devices include vertical barbs for vertically retaining portions of an upper end of a geotextile fabric layer on upper portions of the posts. The end silt barrier attachment devices include horizontal barbs for laterally retaining end portions of the geotextile fabric layer on end posts. The inward silt barrier attachment device includes first and second sets of horizontal barbs for removing lateral slack from inward portions of the geotextile fabric layer.

An elongated polymeric impermeable geomembrane sheet having opposing first and second surfaces with a plurality of spaced-apart first projections extending from the first surface, said first projections each tapering to a pointed apex at a distal extent, which first projections for mechanically engaging a synthetic drainage geomesh sheet overlaid by a tufted geotextile sheet and in contact with adjacent fill materials within the aggregation, whereby the aggregation has increased resistance to shear failure of the aggregation of fill materials and reducing stabilization failures of materials aggregation applications. A ground covering closure system is disclosed.

A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.

The present invention relates to a water barrier, in particular a dike, comprising an inner slope, a crown and an outer slope, wherein the outer slope is located on the waterside. The water barrier is characterized in that the natural vegetation of at least one of the elements of inner slope, crown and outer slope is provided with fibres inserted into said vegetation.
