We need advice on the best economical way to repair concrete basement walls . The walls are crumbling ( the house was built circa 1915) and there's evidence that moisture has been seeping in. We want to repair the walls to assure no further deterioration and to create a surface that can be painted . As this basement is to be used as a studio, we would like to be able to present a pleasant atmosphere both for the artist at work and the customers/visitors that are expected. Any and all suggestions are appreciated.
