Hello Gremlin and welcome to the community!


Your fix is easy but time consuming, and you can use either of the products below. 


DRYLOK Fast Plug Hydraulic Cement


Quikrete Hydraulic Water Stop Cement


To chisel out the concrete you need to use Cold Chisel and hammer, don't forget eye protectionYou'll also need a cheap mixing container, a small plastic putty knife, a screwdriver, and protective work gloves. 


The tie rod leaks can be repaired at anytime, there is no need to wait for the water to stop. When mixing the hydraulic cement, make sure to only mix small batches, this stuff dries very fast--approximately as much as you can use in two or three minutes. This is normally one rod hole, a couple more once you become adept at it. But for now, concentrate on just the first patch.  


With a hammer, tap very lightly on the metal tie rod. The tapping will cause some of the outer coating of the tie rod to come off. When you reach the rod hole, the coating will come off much faster, and eventually leave a dent in the wall. At that point, take your screwdriver and work it into the hole, twisting and removing all the loose material. 


Mix up up some hydraulic cement, again small batches at a time, with the consistency of peanut butter, take your putty knife and push some into the hole, as much as it can handle.

This is a good process for basement walls that have the metal rod in the wall which is known as "snap ties". Many basements have the ties removed leaving a 5/8th inch hole in the wall every 18 inches. In this case, you can use the TRX Compressed Swell Plug found at This product is a water activated swell plug that seals first with compression, then the body is activated by water causing a long term water tight seal.
