Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.

A landscaping tie system comprised of landscaping timbers and connectors. The landscaping timber comprises four flat boards each having an inside face, an outside face and two end edges. The four flat boards are mounted onto a center joint so that the four flat boards define a perimeter face of a timber and an inner channel inside the perimeter face, whereby the center joint is positioned within the inner channel. Two landscaping timbers may be joined by a connector with an outer profile to nest within the channel of each of the two landscaping timbers to establish an increased size timber arrangement.

Disclosed are biodegradable insulation materials comprising a structural scaffold; and at least one temperature resilient fungus. Also disclosed are methods of making and using biodegradable insulation materials comprising a structural scaffold; and at least one temperature resilient fungus. For example, disclosed are methods of insulating an infrastructure comprising administering the disclosed biodegradable insulation materials to an infrastructure.

A permanent wood foundation wall which includes a frame having a first member, a second member spaced apart from the first member, and two side members. The first member, second member, and two side members each have a front surface and a rear surface that form the front frame surface and the rear frame surface. A cavity is formed between the front frame surface and the rear frame surface of the frame and the first member, second member, and two side members are formed from a wood material including a preservative. Further, the permanent wood foundation wall includes a sheathing board having a first side attached to the rear frame surface of the frame and a second side opposite the first side, a waterproofing membrane applied to the second side of the sheathing board, and a foam layer formed within the cavity of the frame.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

A cover for an underground enclosure may include an upper surface comprising a pattern of bosses, a first slot and a second slot disposed on the upper surface, a lower surface opposite the upper surface. A first reinforcement member may be coupled to the lower surface. The first slot may extend into the first reinforcement member, and a second reinforcement member may be coupled to the lower surface and aligned with the first reinforcement member. The second slot may extend into the second reinforcement member. The cover may be configured to be lifted by the first slot and the second slot.

A cap assembly can include a cap holder device with a plug member and a cap holder. The cap holder device is positionable in an end of a conduit positioned along a roadway. The cap holder is carried by the plug member and includes a magnetic element and a connector. The connector is connectable to the magnetic element to the plug member such that the magnetic element is movable relative to the plug member so as to position the magnetic element for releasably holding a cap that covers the end of the conduit when the plug member is positioned in the conduit. The cap assembly can be a debris cap insertable in a conduit, an end of a pipe, or other opening.
