We have house built in 1965. We would like to install rubber matting in a quarter of our basement for a home gym. Each mat weighs about 100 lbs. and we would use approximately 14-16 mats. Would the concrete slab be able to support this much weight in just one section of the basement? The room is roughly 21x15 ft

I had an indoor French drain installed in half my basement. Pic shows it done except for the cement on top of stone. There is a 4 inch pipe below the stone and it all goes to the sump pump. I was going to finish the other side myself to save myself about $4000 dollars. I read at some point about something called a gravity drain in the basement where it's all the same work but you don't add the 4 inch corrugated pipe. What is a gravity drain?
