Abstract: Embodiments of methods and apparatuses to measure a concrete foundation from within the concrete in order to maintain the foundation in a controlled flat condition over time we disclosed. A method, for example, may include placing a conduit network inside forms of a concrete foundation, documenting the conduit network in X and Y coordinate system, pouring the concrete foundation with the conduit network inside the concrete in generally the same position, passing an elevation measuring sensor through the conduit network to record a baseline elevation of the conduit and using this baseline for relative comparisons in the future. An embodiment of a method also may include using the relative change in the conduit elevation to predict the relative risk of a repair and financial losses and using the relative change in the conduit elevation to assist in the proper repair and maintenance of the foundation.
