Abstract: A unidirectional geotextile fabric for use in reinforcement of earthen retaining walls, embankments, slopes and related structures. The fabric is an open grid of high modulus of elasticity strands extending in the weft direction and strands of comparatively lower modulus of elasticity material extending in the warp direction. The fabric is preferably coated with a curable resinous material of sufficient thickness to protect the glass strands from breaking as the fabric is rolled onto cores and unrolled at the job site. When laying the fabric, a roll of the fabric is placed at one end of the face of the earthen structure being constructed and simply unrolled in a direction generally parallel to the structure's face. Because the high modulus strands of the fabric are the weft strands they extend and inhibit soil movement in a direction substantially perpendicular to the face of the structure.

Abstract: A geotextile fabric constructed as a bi-axially oriented, open grid of high modulus of elasticity strands impregnated with resinous material which is flexible when cured. The fabric may be stored and installed in roll or sheet form and provides high-strength, low-strain reinforcement of earthen structures which is resistant to abrasion, water and chemical attack from soil.

Abstract: This invention provides reinforced, water-resistant membranes, and methods of manufacturing and installing such membranes. These membranes include a mastic layer having first and second major surfaces and a fiber-containing reinforcing layer disposed within the mastic layer for improving the mechanical strength of the membrane. The membrane can be bonded to an underlying substrate by the application of heat or pressure to form an adherent bond. The reinforced membrane of this invention can have a tensile strength of at least about 300 psi or more.

Abstract: This invention provides reinforced, water-resistant structures, and methods of manufacturing and installing such structures. These structures include bituminous mastic material having first and second major surfaces and semi-rigid, open mesh material disposed within the mastic material. The structure may be prefabricated or assembled in situ and can be bonded to an underlying substrate by the application of heat or pressure to form an adherent bond. The reinforced structure has a tensile strength of at least about 300 psi or more.

Abstract: Conduit liners and methods for their construction and use are provided. The liners include a first flexible layer mechanically bonded to at least one glass-containing layer and folded to form a tubular laminate. The laminate can be penetrable by resinous liquid capable of setting the form of substantially continuous matrix within the laminate following the expansion of the laminate within a conduit. In preferred versions of the liner, multiple glass layers are provided on the inner and outer diameter of the construction with a polyester core so as to meet minimum thickness requirements for vibration resistance under American in situ pipe vibration resistance codes.
