  • Patent number: 7670415
    Abstract: Systems and methods for enhanced moisture vapor barrier performance for concrete-containing materials and surfaces are disclosed. Treatment modalities that include addition of the disclosed materials, compositions and systems to pre- and post-construction concrete-containing materials and surfaces are provided. Moisture vapor barrier properties are effected over an extended period of time as compared to control systems. The disclosed compositions and systems also yield reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces and, despite the water soluble properties of the compositions and systems, the treatments are effective in delivering an advantageous level of liquid moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C9 to C16 branched hydrocarbons of varying structures.
    Type: Grant
    Filed: August 31, 2007
    Date of Patent: March 2, 2010
    Assignee: Hycrete, Inc.

  • Patent number: 7513948
    Abstract: Systems and methods for enhanced autogenous healing of cracks that are formed or are present in concrete-containing materials and surfaces are disclosed. Treatment modalities that include addition of the disclosed materials, compositions and systems to pre- and post-construction concrete-containing materials and surfaces are provided. Autogenous healing is effected at a greater rate and to a larger degree as compared to control systems. The disclosed compositions and systems also yield reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces and, despite the water soluble properties of the compositions and systems, the treatments are effective in delivering an advantageous level of moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C9 to C16 branched hydrocarbons of varying structures.

  • Patent number: 7407535
    Abstract: Water soluble materials, compositions and systems for use in treating concrete-containing materials and surfaces are disclosed. Treatment modalities that include addition of the disclosed materials, compositions and systems to pre- and post-construction concrete-containing materials and surfaces are provided. Reductions in the rate and/or impact of corrosion are achieved for concrete-containing structures and surfaces. In addition, despite the water soluble properties of the material, composition or system, the treatments are effective in delivering an advantageous level of moisture resistance to the treated concrete-containing structure and/or surface. The composition is synthesized from a feedstock that includes C9 to C16 branched hydrocarbons of varying structures.

  • Publication number: 20080038473
    Abstract: A combination includes a composition providing corrosion resistance for application to a post-construction material, and a post-construction material, wherein the composition is applied to at least one surface of the post-construction material after the post-construction material has hardened. The composition may include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition. The composition may be an aqueous solution of a metal salt of a dioic acid. The post-construction material may be reinforced or unreinforced concrete. The post-construction material may be a concrete-containing structure, and the composition may be applied to an exterior surface thereof.

  • Patent number: 7261923
    Abstract: A composition of a solution of a metal salt of a dioic acid that provides corrosion resistance and moisture resistance is disclosed for application to post-construction materials. The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition for application directly to the surface of the post-construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like.
