Drainage Mistakes That Impact Your Foundation Queens, NY Basement waterproofing is much more than installing a waterproofing system at the basement level. Drainage around the foundation is a vital part of waterproofing. A good drainage system will ensure that your foundation is protected from runoff when it rains or when snow melts. If this water is not channeled away from the home’s foundation, it will saturate the soil and destabilize your foundation. If you engage an experienced and skilled basement waterproofing contractor, they will not only work to install a waterproofing system at basement level but also help you ensure that all other drainage issues are dealt with. Poor drainage will not only make your waterproofing system work harder but may also overwhelm it and cause serious damage to your foundation. The following are some drainage mistakes that you should avoid in order to ensure the safety of your foundation.
