My wife and I would like to put some new flooring in our house, and really like the look of bamboo. Our house is on a slab and is currently carpeted throughout, and we are wondering what our options are. At one point I thought I had read that, since all we have under the carpet is the concrete slab, that click lock flooring was our only option. After doing some searching online though, I've found some conflicting information. I'd like to get the opinion of people here as to whether click lock or typical tounge and groove flooring would be best for us in this situation. If it makes any difference, we'd be installing it in a large portion of the house, including our living room which is HUGE. I don't have the exact measurements with me at work, but it is a very large room. If one type would work better in our situation then we'd obviously choose that. If either would work equally well then we'd rather do whatever would be cheapest.
