Hi folks! I’m hoping someone can give me some advice on a problem I’m having with some concrete I had poured recently. In my backyard as a patio we had a concrete slab poured which is 50 feet along the house and 12 feet out towards the backyard. It looked beautiful the first couple of months!! But then a crack appeared at one end. And now that crack has spread all the way across the 50 foot slab. Right down the center of it. It’s a hairline crack which eventually is going to get bigger .... chips, weather. I’ve called the company that poured it but they are avoiding me. Is there a way to disguise it? What should I do?
