The plastic pipe that carries our electrical wires from the outside meter on the side of our house to the inside electrical panel has developed a leak under the garage concrete floor and now after a rain storm water leaks into the electrical panel and out into the basement.  Is there any non intrusive way to find the leak or fix the leak without breaking the concrete floor?

Bob, other than digging and replacing, your options would be to either run the conduit through an alternate route, or possibly seal the ends of the conduit. I suggest contacting a electrical contractor for his opinion and expertise.
