Hi! First post to Reddit. What material are people using to repair cracks in the basement floor? My cracks are approx. 2-3mm wide and 3m or so long. The building store has specific material (in caulking tube format) for concrete crack repair. In my experience, when used outdoors, this stuff cracks again over time. So I'm wondering if silicone would be a better option? Thoughts?
