This company sells solid waterproofing
This company sells solid waterproofing materials. I waterproofed for 6 years and these products are top of the line. It's hard to find the right materials for interior waterproofing unless you have a waterproofing company do it. The lifetime membership is a great deal for the ability to purchase products at a reasonable price. The product shipping rates and time received is top notch. I look forward to doing business with this company for may years.
