Abstract: In a method of reinforcing a pipe, a water penetration resistant layer and strengthening layer of fibrous material are impregnated with a curable polymer, positioned in a lining position near the pipe, and cured to form a water penetration resistant liner and a strengthening liner. The two layers can be impregnated and positioned separately or at once, for example, as a composite liner. Together, the liners provide a waterproof barrier and structural reinforcement to the resulting pipe. In a method of waterproofing a reinforced pipe, a water penetration resistant layer is impregnated with curable polymer, positioned over a previously installed reinforcing liner, and cured to form a waterproof barrier inhibiting ground water egress into the pipe. In certain embodiments of the methods, the water penetration resistant layer includes fibers woven in one of a satin weave and a twill weave.

Abstract: A method of repairing a section of a pipe including a breach in the pipe. A surface of a wall of the pipe is prepared generally around the breach. A piece of conformable material of the type capable of carrying a curable polymer is sized in relation to a size of the breach. The sized piece of conformable material is applied to the prepared surface so that the breach is covered by the piece of conformable material. The piece of conformable material is impregnated with a curable polymer. The curable polymer is cured within the piece of conformable material thereby to seal the breach against egress of groundwater into the pipe.

Abstract: A method of lining an interior of a pipe in need of repair comprises providing a carrier tube having one or more expandable materials, coating the carrier tube with a binder, securing one or more layers of a fiber-laden material along an exterior surface of the carrier tube with the assistance of the binder.

Abstract: A protective casing for a vessel includes an outer shell surrounding the vessel wall. A spacer extends from adjacent the vessel wall toward the outer shell and spaces the outer shell away from the vessel wall. The spacer permits substantially uninhibited deformation of the outer shell to failure inward toward the vessel wall when a missile impact is imparted on the outer shell such that the outer shell substantially dampens the transmission of the energy of the missile impact to the exterior vessel wall. The spacer can position the outer shell to allow reinforcing fibers of the outer shell to elongate to the yield point to maximize energy absorption. Embodiments of the protective casing and a protected vessel, as well as a kit and method for forming the protective casing, are disclosed.

Abstract: A high strength liner can be applied to pipes in a very thin layer and yet provide the ability to withstand high operating pressures. The liner is useful for any pipe, but has particular application to small diameter pipe where there is less room to accommodate a reduction in diameter caused by pipe lining. Methods for lining are also disclosed.

Abstract: A method of reinforcing a column positioned proximate a blocking structure that prevents wrapping a sheet material completely about the column. The column includes an exterior perimeter surface portion extending between first and second intersections with the blocking structure so that the exterior perimeter surface portion is accessible from one side of the blocking structure. A first opening is formed in the column and/or the blocking structure. The first opening is located proximate the first intersection of the exterior perimeter surface portion of the column and the blocking structure. A portion of the first fiber anchor is inserted through the first opening. The first fiber anchor has at least a first end. The first end of the first fiber anchor is secured to the exterior perimeter surface portion of the column. An outer fibrous sheet is applied to the exterior perimeter surface portion.

Abstract: According to some embodiments, a cable protection system to at least partially shield a cable from heat, fire, an impact or other potentially harmful event or occurrence comprises a first encompassing member configured for placement around the cable or cable bundle, wherein a first void is defined between the first encompassing member and an outside of the cable or cable bundle. The system additionally includes a second encompassing member positioned around the first encompassing member, wherein a second void is defined between the first encompassing member and the second encompassing member. Further, the system comprises one or more fill materials positioned within the second void. In some embodiments, the fill material comprises vermiculite, ceramic and/or one or more other materials. The first void permits the cable protection system to be slidably moved relative to the cable or cable bundle.
