Hello! We live in the Chicago area in a two-story house without a basement, so our first level is a slab. One year ago we completely renovated our first floor. We used to have laminate on the first floor, but the pieces were separating from one another — we could slide them across the floor at least by a few inches near the old cabinets. When we redid the floor, we installed a stranded, waterproof bamboo with a rubber backing. Within a few months the bamboo was already splitting and some of the boards are popping up. We’ve replaced boards but it keeps happening. The contractors who installed the bamboo did not level the concrete first — they insisted that they did not need to. Now, only one year later, we are looking to replace our bamboo floors. I don’t know if the problem is due to poor quality bamboo or due to not leveling, or both. We had installed a plastic vapor barrier under the bamboo, with an underpayment on top of that. I am not struggling with what kind of flooring to install. We can’t keep replacing the floors — this is costing us a fortune. I was considering the luxury vinyl floors, but I worry about VOCs and chemicals. I am open to laminate, and was also considering engineered hardwood. We have kids and a dog so need something that is durable. Please send me your recommendations for the best flooring for a first floor slab, as well as installation recommendations. This will be installed on the entire first floor — kitchen, bathroom, living room, family room. I want the installation done right, so we don’t have to replace the floor a year from now again! I attached photos of the splitting bamboo. Thank you so much!
