Concrete Cracks – How to fix

You’ve heard the old saying about concrete right?

“There is two types of Concrete:  Concrete that’s cracked, and Concrete that’s going to crack!” -Old Man Builder

Well, this blog post is about a problem that most builders will face at some point in their career.  I built this house 10 years ago, and it was my first house with a polished basement concrete slab.  Within about a year’s time this slab exhibited some cracking.  Keep in mind that these cracks are not structural issues, and this fix I’m about to show is strictly cosmetic.

I’m using a two-part polyurea (it’s kinds like a cross between epoxy and spray foam) product called RS-88 from Metzger/McGuire that guns out of two tubes into your joints.  Metzger McGuire Website for more info.  Here’s some detailed pictures but you can see more in the video.

Not fun work, but it went pretty fast.  We did the entire basement in 2 hours.

After curing (about 20 min) it scrapes off flush easily.

As an aside, I learned about this product by buying from a local supply house that’s focused on Commercial Construction.  If you are in Texas or Oklahoma you can buy this at All-Tex Supply.  http://all-texsupply.com/  Alternatively, here’s the RS-88 on Amazon.
