Abstract: A method for testing whether a sealing method is effective may include the steps of testing a flow characteristic of the substrate, sealing the substrate, re testing the flow characteristic of the substrate, then comparing the before and after flow characteristics of the substrate to determine whether the sealing step was effective or to quantify a sealing effectiveness to the sealing step.

Abstract: A crack filling method includes forming a first drill hole in a concrete structure, with the first hole extending into a crack formed in the concrete structure. A test hole is additionally formed in spaced relation to the first drill hole. A baseline flow test is conducted by directing a test liquid into the test hole to determine a baseline flow characteristic. A filling substance is injected into the first drill hole and into the crack to at least partially fill the crack. Subsequently, a quality flow test may be conducted by directing the test liquid into the test hole to determine a quality flow characteristic following hardening of the filling substance in the crack. The quality flow characteristic may be compared to the baseline flow characteristic to determine an effectiveness of the crack filling.

Abstract: A crack filling method includes forming a first drill hole in a concrete structure, with the first hole extending into a crack formed in the concrete structure. Other structures and applications are also contemplated such as joints and injection tube systems.

A baseline flow test is conducted by directing a test liquid into the test hole to determine a baseline flow characteristic.
