Disclosed are exemplary embodiments of turf reinforcement mats that include spun yarns and/or multifilament yarns in either or both of the warp and weft directions.

A polypropylene composition is described having an MFI measured according to ISO 1133 for polypropylene of 1 to 3 g/10 min and a xylene soluble content in the range from 1 wt % to 4.5 wt % or 1.5 wt % to 4.5 wt %, which can be used to produce spun and drawn fibres having an average MFI measured according to ISO 1133 for polypropylene of 1 to 5 g/min, a xylene soluble content in the range from 1 wt % to 4.5 wt % or 1.5 wt % to 4.5 wt %, the spun and drawn fibres having an average elongation of at least 65% as measured by ISO 5079 with an adjusted testing speed of 80 mm/min, and/or an average tenacity/tensile strength of at least 56 c N/tex as measured by ISO 5079 with an adjusted testing speed of 80 mm/min.

Disclosed are exemplary embodiments of woven geotextile fabrics with integrated geotextile grids or geogrids. Also disclosed are exemplary embodiments of methods of manufacturing woven geotextile fabrics with integrated geotextile grids or geogrids.

A sack for realising civil engineering works, including a sack structure with two main faces defined by two respective equal main expanses of cloth that are joined over most of their periphery. The main expanses of cloth define an opening for introducing filling material into the sack structure when in use. The sack comprises at least one expanse of protective cloth whose resistance characteristics differ from the main expanses of cloth. The expanse of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.

Disclosed are exemplary embodiments of woven filtration fabrics that include core-sheath spun yarns in either or both of the warp and weft directions.

Disclosed are exemplary embodiments of turf reinforcement mats that include spun yarns and/or multifilament yarns in either or both of the warp and weft directions.

A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.

Described herein is an anti-capillary barrier geotextile which includes a wicking yarn in its structure and has a volumetric moisture content at breakthrough of less than 0.30 as determined by the TenCate Test. In one aspect the anti-capillary barrier geotextile is a single-layer woven geotextile and includes a wicking yarn set and, optionally, a first non-wicking yarn disposed in one axis of the geotextile; and a second non-wicking yarn disposed in another axis of the geotextile and interweaving the wicking yarn set and optional first non-wicking yarn.

Disclosed are exemplary embodiments of woven geotextile fabrics. In exemplary embodiments, a geotextile has a high water flow rate, such as a water flow rate of at least 125 gallons per minute per square foot, etc.
