When moisture permeates concrete slabs or walls below grade, how can this problem be solved and does it require excavation?

From Peter J. Bakke of Midwest Industrial Coatings-WI, LLC on April 6, 2011:
     The problem can be resolved by addressing the moisture where it originates, on the positive side of the slab. This is accomplished by injection of a polymer grout.  This bitimous clay product has huge water absorbtion capabilities. The equipment and process is easy to use and easy to move around. The supplier has national and regional installers. The product, Bentogrout, has been in the industry since the early 80's and to date is the only product that allows you avoid excavation by treat the positive side of the wall.

From Wayne Salisbury of Conproco corp on March 29, 2011:
    This problem may be resolved without excavation by treating the negative side. Any active leaks must first be plugged. The surface must be prepared by opening up the cement. Then, a crystalline-based cementitious water seal coat is applied to the surface, usually in two coats.This approach will often solve the problem.
