I have been a basement waterproofing expert for 21 years in the Chicagoland area. There has never been a basement or wall that I have not been able to waterproof. I have used all the products out there and even created my own procedures that have been successful. The products used to waterproofing and the methods change almost every year. I have made waterproofing my life hobby and profession and I share with you every single piece of knowledge that I have acquired. If you are considering waterproofing your residential or commercial building and you have questions, more information can be found on my website.
