Epoxy shield concrete patch and repair by Rustoleum is a great product but
you need to call Rustoleum and verify how it does against water pressure.

There is a small concrete pit right outside our garage containing a sump
pump that keeps our garage dry in the winter. There is a pinhole leak in
one corner, the tiny stream of water that comes in this hole after a heavy
rain eventually fills the pit which in theory is supposed to stay dry
while the drain channel in the driveway feeds the pump which is enclosed
in it's own plastic container. The problem is that long after it stops
raining this leak results in the sump pump trying to drain all the ground
water above the level of the leak. I'm looking for recommendations of
products to apply to the concrete in that corner which will seal the leak,
I've heard of paint-on products. Or do I have to bite bullet and slap
some hydraulic concrete all up that corner to have a realistic chance of
sealing the leak?
