Problems solved by technology

Such repairs often require the replacement of a length of pipe, as repairs to small sections of pipe by welding, patching, or other methods are often unsatisfactory, and because the diameter of the pipe does not permit safe human access, Repair of small sections of pipeline is therefore difficult or even impossible
In the case of underground pipes, pipe replacement is difficult, expensive and time consuming

Abstract

A reinforced liner and methods of manufacturing the liner are disclosed. The liner includes a glass veil layer as an innermost layer in combination with an outer reinforcing layer that includes glass fibers. The glass veil layer and the reinforcing layer are joined together, such as by an elastic yarn. Inclusion of the glass veil layer imparts desirable surface finish characteristics to the reinforced liner.

Description

technical field [0001] This application claims priority to US Provisional Application No. 61 / 714,514, filed October 16, 2012, which is hereby incorporated by reference in its entirety. [0002] The broad inventive concept relates to linings for repairing subterranean piping systems, and in particular to reinforced linings with improved performance for such repairs. The broad inventive concept also relates to methods of making such linings. Liners are useful in the repair and restoration of damaged and / or aged piping systems. Background technique [0003] Underground piping systems are essential to transport liquids and gases to homes and businesses. Utilities typically use these piping systems for sewers, water channels, gas channels, and other applications. This piping system is installed several feet underground, and therefore access to the piping system is limited. [0004] Underground pipelines are subject to cyclic loading, early wear, corrosion, porosity and enviro...
