My name is Daniel J OConnor. I am the founder and single owner of Hydroarmor Systems. ( Duh,,, ) Most other Companies and Company owners have been taught "in the box" standards, sell u the standard and do the standard. Your wallet is not a consideration and the "standard" can cost you way more than you need to pay. Everything I do is "out of the box" my way. This kind of repair came out of my brain. There might b others who have thought this up and do it also but to me this one is mine. And this repair should absolutely save you 25% of the cost to replace the wall. Daniel J Connor
