I'm digging out my basement and am seeing water flow in because the water table is very high right now. My thoughts are that once I cemented the basement and created a sealed box so to speak the water would not come in. My neighbor disagrees and says the water will lift the cement floor. I've dug down 3 feet so far and prior to this dig out I only had water come in on occasion, not nearly what I'm seeing now. I find it hard to believe that 3 feet of compressed dirt would prevent water and 12 inches of concrete would not.
Am I wrong?
