Abstract

A method of crack repair for building and paving material which lowers an existing surface (S) to a new working surface (W) which is low enough to effect repairs without changing the elevation or attitude of the original surface: which fills the crack (C) with grout (1) which is in turn sealed by a bridging material (2). An initial overlay material (3) is placed over the bridging material and a reinforcing strip (4) embedded in the overlay material followed by a second layer of overlay material (5) sufficient to return the repaired area to the elevation and attitude of the original surface.

Claims

1. The method of crack repair for building and paving material, comprising the steps of:

a. lowering the original surface in the area surrounding the crack to a depth sufficient to effect repair of the surface without changing the elevation or attitude of the original surface, and

b cleaning and filling said crack with a crack filling material, and

c. applying a flexible fabric bridging material containing an adhesive which adheres to said crack filling material and said existing building or paving material and which has a glazed upper surface with a low coeffecient of friction which discourages bonding with additional repair materials which will be placed above said bridging material, and

d. application of an initial overlay material over said bridging materail, and

e. embedment of a reinforcement material within said initial overlay material, and

f. application of a second layer of overlay material over said initial overlay natural in an amount sufficient to bring the new surface flush with said original surrounding surface.

2. The method of crack repair of claim 1 for building and paving material consisting of:

a. a sequence of constructed elements which will reduce surface and near-surface stress to the point where re-cracking of said surface is prohibited, and

b. effecting repairs without altering the elevation or attitude of said original surface.
