Waterproofing Long Island homes can be a challenge for DIYers and inexperienced waterproofing companies because there is no one-size-fits-all solution. The soil composition, ground layout, and building structures of Long Island are unique in that there is so much variation from area to area. Because of this, Long Island basement waterproofing solutions vary greatly from one house to another. To solve the issue, an accurate diagnosis of the problem is crucial.
