I have been a basement waterproofing expert for 21 years inside Chicagoland area. There has never been a basement or wall that i have not been capable to waterproof. I have used all the products out there and even created my own procedures which were successful. The products used to waterproofing and the methods change just about every year. May possibly made waterproofing my entire life hobby and profession and I give out every single piece of knowledge that i have acquired. If you are considering waterproofing your residential or commercial building also, you have questions, more information are found on my website.
