Installed basement bathroom, now getting water in basement

Hello,
We recently installed a Liberty ejection system for our basement bathroom. In order to install this, the plumber dug out our foundation, installed the system, and then replaced the cement. In 30 years of home ownership, we have never seen a drop of water in basement. Once this bathroom was installed, we have gotten water twice (about 0.5 inch of water in the entire basement). Our general contractor has recommended we remove the Liberty system, fill the holes with hydraulic cement applied very thick, and to go with an above-ground basement toilet system (such as the systems with the elevated toilet).

We are very nervous about getting water again and the effectiveness of the hydraulic cement in keeping water out. Does anyone have any experience with this or any other advice on how to keep water out? We don't want to re-finish our basement until this is resolved. Thank you!

When you get this water coming in, does it come in through the cracks where the old cement meets the new cement?

If yes, then it sounds like the plumber (not a mason) didn't take the time (or didn't know) to bond the new cement to the old cement. Remove the new cement, clean the surface of the old cement, add a bonding coat, rebar, and install fresh cement.

If the water is backing up through the pipes, let us know that too.

You got it exactly right. At first we didn't realize where the water was coming from but upon further inspection we realized that the water was coming up in the area where the new cement meets the old. We don't believe that the plumber used hydraulic cement which we were told would have prevented the water from coming in. The plan now is to remove the entire Liberty ejection system and fill that hole with hydraulic cement and to your point, ensure that it is done correctly. We are just worried that water will find its way back, but we were told that the hydraulic cement should do the trick if applied correctly. Then we would look to install a fully above-ground toilet system. What are your thoughts on this? Thank you so much.

While I am not familiar with the Liberty system, I believe fixing the concrete alone should correct the problem.

is the libery system where a pump will pump the waste to the main waste line when a proper grade cant be achieved. we were talking about a similar system on site last week with the plumber, however it goes by a different name here.

i completely agree with houston how it sounds like the plumber didnt glue the pipes. as for the concrete, technically if the bathroom was plumbed correctly the cement shouldnt make a difference unless there are moisure problems beneath the slab

The Liberty system is an underground pump that hooks into your existing sewer line and pumps out the waste. This system itself is not the issue - it worked great. The issue was that when the foundation was broken in order to install the pump underground, the seal between the pump, which is plastic on the outside, and the concrete of the foundation was not enough to fend off water from two HUGE storms and an already saturated ground. Therefore, to avoid the risk of another basement flood, we are going to remove the Liberty system and fill the holes with cement as described above. We are pretty sure normal rain storms wouldn't have given us issues with water; however, this winter we had an enormous amount of snow, which was melting just as we got two huge rain storms with over 3" of rain each.

Note, we also believe some water was coming up from the space where the new concrete met the old, so we don't believe the new concrete was installed correctly. We are taking precaution when we re-fill the holes - using a bond agent as well as hydraulic cement.
