Fixing Concrete Cracks in a Basement Slab
Builder Matt Risinger demonstrates one method for making cosmetic repairs to non-structural cracks in concrete.
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. I found this when I was buying waterproofing supplies at a Commerical Contractor’s supply house, and I was overjoyed to find this easy fix for a common problem. Metzger McGuire Website for more info.
