摘要： This invention relates to a method of repairing existing manholes and similar structures by applying a fast-curing elastomeric material using spray techniques whereby a homogeneous, non-porous, and monolithic coating or lining is formed. The fast-curing elastomeric material can be applied directly to existing concrete, brick, tile, mortar, and metal surfaces normally found in sewer manholes and catch basins, sewer and drainage pipes, parking decks, bridge piers and footings, holding ponds, bridge trusses, culverts, gratings, and the like and does not require any formwork. The elastomeric coatings provide effective surface protection against wear, corrosion, and water infiltration and can be applied in a single operation to horizontal, vertical, and overhead surfaces. The elastomeric materials are prepared by initiating the reaction of an isocyanate-terminated compound or polymer with an amine-terminated polymer or an aliphatic or aromatic diamine immediately before applying the elastomeric material to the surface to be coated. Preferably the reactive components (i.e., isocyanate-containing and amine-containing materials) are mixed directly in the spray gun used to apply the elastomeric material.

摘要： This invention relates to a method of repairing existing manholes and similar structures by applying a fast-curing elastomeric material using spray techniques whereby a homogeneous, non-porous, and monolithic coating or lining is formed. The fast-curing elastomeric material can be applied directly to existing substrates, which may comprise of concrete, brick, tile, mortar, and metal surfaces normally found in sewer manholes and catch basins, sewer and drainage pipes, parking decks, bridge piers and footings, holding ponds, bridge trusses, culverts, gratings, and the like and does not require any formwork. More preferably, the substrate surfaces are first cleaned and primed to improve the bond of elastomeric coating to the substrate. The most preferred primer is an aqueous solution of silane, preferably containing 10% to 30% silane. The elastomeric coatings provide effective surface protection against water infiltration, wear, and corrosion and can be applied in a single operation to horizontal, vertical, and overhead surfaces. The elastomeric materials are prepared by initiating the reaction of an isocyanate-terminated compound or polymer with an amine-terminated polymer or an aliphatic or aromatic diamine immediately before applying the elastomeric material to the surface to be coated. Preferably the reactive component (i.e., isocyante-containing and amine-containing materials) are mixed directly in the spray gun used to apply the elastomeric material.

摘要： A method of filling a seam of a structural panel assembly utilizes a non-foaming, thixotropic, two-component polyurethane elastomeric material. The thixotropic, elastomeric material is prepared by rapidly mixing and initiating the reaction of a first thixotropic component comprising an isocyanate-terminated compound having at least two reactive isocyanate groups and a second thixotropic component comprising a hydroxyl-terminated compound having at least two reactive hydroxyl groups. Each of the first and second thixotropic components include from about 3% to 8% by weight fumed silica. The second thixotropic component also includes from about 10% to about 50% filler. The thixotropic elastomeric material is applied over the seam of a panel assembly. The method then includes fluidizing the thixotropic elastomeric material and driving the thixotropic elastomeric material into the seam of the panel assembly. The thixotropic elastomeric material is then allowed to cure in the seam, thereby sealing and reinforcing the seam of the panel assembly.

摘要： A cap for sealing waste in a landfill is prepared by disposing a fill layer atop the waste and applying a fast-curing elastomeric material to the fill layer to provide a monolithic, continuous, elastomeric coating thereupon. The elastomeric material is derived from the reaction of an isocyanate-terminated compound having at least two reactive isocyanate groups and an amine-terminated compound having at least two reactive amine groups. The elastomeric layer is preferably covered with a porous drainage layer which is in turn covered with a layer of soil.
