Best surface/mat for high impact workouts?

I love working out at home, but I can't help but worry for my joints every time I do high-impact HIIT workouts (I've got concrete floors!) I have an exercise mat for floor exercises (core exercises, stretching, etc.) but I'm looking for something with a larger surface area to absorb the impact and stay in place through all those jump squats, burpees, high knees, etc. Something that I could roll up or take apart to store easily would be ideal since I don't have a full dedicated home gym space. I've seen a lot of reviews saying that the puzzle piece-style foam mats don't stay together well and compress over time with more intense exercises like burpees and mountain climbers. Anyone in a similar situation and found something that works well?
