Hi Keith This topic comes up often here, so at the expense of sounding repetative.........:-)
Plugging holes from the inside of a basement is a waste of your time and money. Hydrostatic pressure will continue, and stuffing 'hydraulic cement' into one hole will cause the water pressure on the outside to build a bit until it finds another opening and goes there....which means that if you are persistant, you will become a leak chaser until the water pressure pushes your wall in :-(
You must find the outside source of water....90% of the time it is water run-off from the roof through faulty gutters/downspouts or the wash from the downspout is going back against the foundation. This water must be directed away from your foundation, either thru a longer gutter drain pipe, long splash block, routing to a drywell or other means. Try this first.
