Previous reviews when I did the web search. We are building a new house. The basement foundation and walls had cracks. I sent a few photos and talked to their waterproofing specialist Mauricio. He reviewed the photos and explained to me that the type of cracks in my basement are nothing to worry about. These are cold joints which happen when the new concrete is poured over partially set concrete. I greatly appreciated his honest and professional opinion. He didn't try to sell me something that I didn't need.
