Had them come and do a concrete slab. The slab itself looks nice however it is unleveled by over 5 inches. You can feel the difference walking on it. They said it was unleveled so that water can drain from it. I must have dummy written on my forehead. If I wanted an unleveled slab I would have done it myself or hired the lowest estimate I got but I didn't. I hired the most expensive one because I thought I would get the best result's but I was wrong. The most expensive and the worse job. would not recommend.
