Sealing the Walls
Simply applying a coat to the outer walls will sometimes not solve the problem. This is because the concrete has pores that might still cause a moisture problem inside the basement. In this case, a sealer must be applied to all the outer walls. A cement sealer it’s easy to apply and will close all the pores of the concrete. So if coating the cracks on the outer walls which we mentioned above won’t solve the water problem, sealing the outer walls will make sure that the problem is solved.
