Disclosed herein is a repair apparatus and method for pipe and fittings. In one form, the method relates to utilizing fabric-like material which is intermixed with an adhesive. In one form, the adhesive is a two-part adhesive which hardens to a semi-rigid state to avoid stress fractures through repeated expansion and contraction due to physical movement or temperature variation in the pipe and/or fittings. In one form the method and apparatus are particularly useful in thermoplastic pipes. In other forms, the method is particularly useful in metal pipes and fittings, or in non-pipe structures.

1. A method for repairing a pipe having a compromised section, the repair system comprising: a. exposing the compromised section of the pipe;b. cleaning the surface of the pipe upon and adjacent the compromised section;c. drilling blind holes into at least a portion of the surface around the compromised section of the pipe;d. disposing at least one layer of adhesive upon the drilled surface;e. wherein the adhesive is comprised of a compound which cures to a semi-rigid state;f. disposing at least one layer of fibrous material upon the layer of adhesive exterior of the blind holes;g. wherein the layer of fibrous material comprises fibers; andh. wherein a portion of the adhesive is disposed between adjacent fibers of the material when cured. 2. The method for repairing a pipe as recited in claim 1 further comprising the step of abrading the surface around the blind holes prior to applying the layer of adhesive. 3. A method for repairing a pipe fitting comprising a vulnerable portion, the method for repairing the pipe fitting comprising the steps of: a. exposing at least a portion of the compromised pipe fitting;b. cleaning the surface of the area adjacent fitting on both the first and second sides of the fitting;c. disposing at least one layer of adhesive upon the surface of the vulnerable portion and the area of the pipe immediately there around on both sides of the fitting;d. wherein the adhesive is comprised of a compound which cures to a semi-rigid state;e. disposing a first rigid sleeve portion onto the adhesive of the first side of the fitting;f. disposing a second rigid sleeve portion onto the adhesive of the second side of the fitting;g. wherein the first and second sleeve portions are sealed to a first and a second expansion portion respectively;h. wherein the first and second expansion portions are sealed to and extend from the first and second sleeve portions, to a covering portion having an inner diameter sufficient to go around the pipe fitting.
