It's rained for the last three days. There are now new cracks in the basement floor. The old ones have expanded (got wider), but no leaks are detected. I'm a bit concerned... Could this be related to a need to pump the septic? This is a three year old home. I'm not sure if the septic has ever been pumped. The cracks weren't here when I moved in. Should I call an expert or should I just keep my eye on it? Could it be related to house settling? If the cracks get bigger, any idea what I should do?
Thanks in advance for all your help.
