Pipe Lining Materials and Resin Approvals

In addition to individual cities purchasing Perma-Liner materials and resins for their large scale pipe rehabilitation projects, a slew of national regulatory entities approve our installations. Quality control to maintain these approvals is done by an independent engineering firm HTS in Houston TX.

Our materials are NSF International certified, for the protection of human health, and American Society for Testing and Materials (ASTM) certified to maintain specific standards to improve product quality and enhance safety. Our technology is also approved by The International Association of Plumbing and Mechanical Officials (IAPMO) which maintains standards based on particular codes to protect public health. The combination of these certifications and memberships validates Maddrey Enterprises, Inc. as a leader in health and safety.

Patents by Assignee PERMA-LINER INDUSTRIES, LLC

    • Patent number: 9074719
    • Abstract: An apparatus and method that accelerates curing of resin in a liner for a buried pipe includes an air inversion unit connected to an air compressor. The apparatus include a curing cap having an inflation port, a curing port and a drainage port. A remote source of pressurized fluid is placed in fluid communication with the inflation port. The apparatus also includes a manifold having an outlet, a first inlet in valved fluid communication with a heated fluid source, a second inlet in valved fluid communication with a pressurized fluid source and a third inlet in valved fluid communication with the drainage port. A flexible tube is slidably received by the curing port while maintaining a substantially fluid-tight seal. The flexible tube has a first end in fluid communication with the outlet of the manifold and the second end has a substantially spherical guide thereon. The second end of the flexible tube also includes a plurality of perforations to allow fluids to pass there through.
    • Type: Grant
    • Filed: August 1, 2011

    • Patent number: 9074720
    • Abstract: An apparatus and method that accelerates curing of resin in a liner for a buried pipe includes an air inversion unit connected to an air compressor. The apparatus includes an inversion head with an interior inflatable plug. The plug, when inflated, creates a substantially airtight seal thereby maintaining pressure within the liner tube. The inversion head can then be removed from the liner inversion apparatus and a curing cap can be installed. To improve the wetting process, a vacuum head is installed at the inversion head and connected to a vacuum source. One end of the liner tube is attached to the inversion head and curable resin is poured into the opposite end. Vacuum pressure is applied to assist in the movement of the resin through the liner tube, ensuring uniform saturation. The resin is mechanically manipulated through the liner tube as the vacuum pressure is applied.

    • Patent number: 8869839
    • Abstract: An device and method for repairing the junction of a main pipe line and a lateral pipe. The device uses a series of independently controlled bladders to adjust the timing and pressure exerted by the bladders on the pipes. The device also uses a liner assembly of resin absorbent material is formed, with a tubular lateral liner connected to a concentric circular main liner. The liner also includes an opening to facilitate loading of the liner in the device. Upon loading the bladders and resin-embedded liner into a train, the device is positioned and the bladders independently inflated, either concurrently or in sequence, installing the liner assembly onto the pipe. Once the resin is cured, the bladder assembly and launcher are removed from the sewer pipe.

    • Inventors: Gerald D’Hulster, James Gould
    • Patent number: 8590575
    • Abstract: Stretch-resistant liners for lining pipes, pipes lined with stretch-resistant liners, and methods for lining pipes with stretch-resistant liners. The liners are made from a lamination that includes a sealing layer, a strength layer of stretch-resistant woven material that overlies the sealing layer, a support layer of non-woven resin-impregnated material that overlies the strength layer, and a barrier layer that overlies the support layer. The lamination is rolled into a tube and inverted when inserted into a pipe so that the barrier layer is the layer that abuts the interior wall of the pipe, the support layer underlies the barrier layer, the strength layer underlies the support layer and the sealing layer underlies the strength layer is contacted by materials flowing through the pipe.
