I think you have two problems. First, you're not diverting water that is
around your foundation (hence the seepage). You'll probably need drain
tiles (perforated pipe) for that. Normally that would drain into your sump
pump.
Second, your sump pump cannot keep up with the really, really heavy rain.
This doesn't sound right at all. Is the sump pumping to a sewer system or
into your yard? If its going into your yard, then the water is probably
working its way back to your house.
