A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A segmental wall block, soil reinforcing system, and method related thereto, wherein the wall block may be used for constructing retaining walls. In one embodiment, the segmental wall block may include: a front face; a rear face; a slot disposed along the rear face; a troughed top face; a bottom face; a first and second open core extending from the top face to the bottom face; a first side having a tongue; and an opposing second side having a groove, wherein the tongue is shaped to interlock with the groove. A soil system may include: a wall block component including a first configuration of interlocked segmented wall blocks as described, and a stabilizing component. A method of reinforcing soil may include the steps of: installing a leveling pad of concrete or gravel; and providing a soil stabilizing system.

There is disclosed a geogrid in the form of an integral, mesh structure comprising molecularly orientated polymeric material, the mesh structure formed of interconnecting mesh defining elements including elongate tensile elements wherein the molecular orientation of the mesh structure is uniform throughout the extent thereof. A method of making the geogrid is also described and its use in stabilizing, reinforcing or strengthening a mass of particulate material.

The invention is applicable in the field of retaining structures, known as reinforced soil. More specifically, it refers to a facing element for reinforced soil structures and excavation faces and to a structure for reinforcing slope and excavation faces made with the facing element provided for in the present invention. The facing element for reinforced soil structures and excavation faces provided for in the present invention is made of a natural origin material, composite, biological or synthetic, for example a biopolymer such as polylactic acid 100 percent genuine (PLA) or polylactic acid bonded with other elements (composite PLA), composite with a fibre material containing cellulose, such as WPC wood, or natural wood.

A drain assembly for being placed inground includes a first panel and a second panel spaced-apart from the first panel, a plurality of supports extending between the first panel and the second panel, a bottom or pipe extending between a bottom portion of the first panel and the second panel, and a cap extending between a top portion of the first panel and the second panel. The first panel may define a plurality of drainage apertures. A related method is also provided.

A soil reinforcing element for use in a mechanically stabilized earth structure. The soil reinforcing element may include a longitudinal wire including a helical portion and a connection element disposed at a first end of the longitudinal wire and configured to couple to a facing of the mechanically stabilized earth structure. The helical portion included in the longitudinal wire may introduce extensibility to the longitudinal wire under loading conditions.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A fire resistant ground erosion control mat assembly. The mat assembly includes an inner layer of fire resistant milled stone mineral wool material with an upper and a lower layer of supportive nets. Each of the upper and lower nets consist of fire resistant milled mineral foraminous nettings to enable passage of light and water therethrough as a ground positioned emplacement of the inner layer.
