Joseph Coupal - Wednesday, October 21, 2020

While it’s natural that a Homeowner would want to try the DIY route first, the Crackman's Flex Seal case studies will help people find the best solution the first time.

Narrator: It’s time once again for the “Crack Man Podcast” hosted by A1 Foundation Crack Repair. I’m Darren Kincaid here with the Crack Man himself, Rich Comeras. Rich has 30 years’ experience in the construction industry and over 25 years as the president and founder of A1 Foundation Crack Repair. This podcasts provides expert basement waterproofing, concrete repair, and preventative maintenance tips for homeowners and businesses. A1 Foundation’s valuable insight will help avert a disastrous flood within the basement, health problems associated with water infiltration, and protect your biggest investment….your home. The topic of today’s podcast: Can Flex Tape fix a leaking foundation wall crack in Canton, MA?

Narrator: Well alright Rich, sounds like you have another interesting case study about a DIY job that didn’t go as planned huh?

Rich: Yeah, I did. I got a phone call from a woman who was in Canton, MA and told me she can’t fix a foundation crack that went from the top to the bottom. It was about a quarter of an inch wide. She tried it. I asked her, what did you try it with? And she tried to put a little bit of caulk in, and then she put, I guess a new product, that Flex Seal has out called Flex Tape, and I said, why don’t you take a picture of it? So, she took a picture of it and sent it to me, and I looked at it and I said, yeah we can fix that, and she was pretty disappointed that it didn’t work.

I said, we’ll take a look at their website, Flex Seal, and see if they have a guarantee. I believe they do have a guarantee and you can follow through with that. But anyway we went out, we drilled angles to the crack, every 6 to 8 inches, put ports in and tighten up those mechanical ports, and we brought our electric pump in and we connect it to the ports. And we injected a polymer resin that went through the port, through the hole we drilled, into the middle of a crack, and it worked its way towards the outside. And we’ve had quite a bit of rain the past few days, and there was no water coming in, plus we give a 10-year warranty. So, I’m sure Flex Seal works on some things but on this particular case, it didn’t work.

Narrator: Definitely not on basement wall cracks or leaking, right?

Rich: Not on this one and I’ve seen quite a few others where it hasn’t worked.

Narrator: Well, very good Rich. I guess it’s natural that a homeowner would want to try the DIY route first, but hopefully your Flex Seal case studies will help people find the best solution the first time.
