We bring something completely different to basement waterproofing and waterproofing in general. We are not the company to call if you have large amounts of water entering your foundation or basement. However, if your foundation is in somewhat decent shape and un-painted. We can stop the moisture from seeping through your walls and floor that cause stored items from being covered in mold and mildew and make your basement far healthier and a truly usable and dry space permanently.\nWith a one-time application using 100% green products that do not change the surface of your concrete surfaces. You can safely store items or furnish your basement and even install hardwood flooring with confidence. Our waterproofing works by using crystalline technology that enters your concrete going where the moisture goes deep into your concrete walls and floors. When moisture is present these crystals expand up to 16 times their size sealing the moisture out of your basement including cracks and joints.
