Ahh the amount of dust from cutting concrete is WAY WORSE than
sanding, jackhammer better choice.

dust is abrasive, lightweight, goes into cloud might get in furnace
etc.

plus if you jackhammer the repaired concrete is way less likely to
crack.

thew nice smooth edge of masonary blade equals poor adhesion.

ideally the underground drain runs to day light somewhere. gravity
tends to be reliable. even if its a lot of digging you will appreciate
knowing your sump cant fail. plus a 4 inch PVC line can carry way more
water than a backup sump pump

if you must go pump, do TWO, with seperate outlets, completely
seperate everything.

perhaps the primary draind into a downspout line?

thake the backup thru the wall and let it spray out of side of home if
the water will run away downhill.

having just one pump or pump sharing lines etc leaves you more open to
failure.........
