On your sump pump? Did you install a drain field or just a pump
somewhere?

Using a jackhammer dig some paths to the sump from different areas of
the basement, dig down a foot or so haul away the dirt and broken
concrete, lay that 4 inch flexible perforated drainpipe in the hole
after first installing a little gravel as a base then cover the
perforated drain pipe with gravel and cement floor back.

repair floors bad areas, run pipe thru them, then atch cement floor,
wait a month or two and paint if you want.

add dehumidifier and let run year round or put a small fan in a 4 inch
duct and let run to ventilate the area.

I ave fought water, you cant seal it out you can divert it
successfully!

make sure sump drains well away from home, yard slopes from home and
downspout water all goes well away from home
