This guide is meant to help in the evaluation of concrete manure storage facilities (CMSF) presenting structural and leakage problems. This tool has also been developed to help select the appropriate methods and material needed to repair the tanks. The whole approach is divided in different steps, the first one being the detection, quantification and evaluation of the default or damage of the CMSF. The next step is the determination of the means (method, material) needed to eliminate or reduce the damage of defaults. The final step is to evaluate the economics of such repairs or improvements and to estimate the profitability of such measures. This guide is to be used by engineers that have to find a solution to existing CMSF that present leakage or potential problems.

CMSF are important investment in the manure management chain and leakage problems that happen before the CMSF life is over always cause problems to the farmers. In Quebec many CMSF have been reported as presenting problems and few solutions where available. This guide is an attempt to help deal with the situation and solve problems.
