Exclamation MAJOR ISSUE Termite Control Holes in Basement Slab

I bought my first house a year ago and we have had alot of rain this year and in the summer I noticed some water seeping through a hole in my crawlspace. I patched it with hydraulic cement and thought it might fix it.

A few months passed and we have gotten 10 inches of rain in one day and now I have water still coming through that hole and it ruined my carpet, so I ripped it out and discovered a series of holes drilled along the slab of the basement rooms (mind you theese are carpeted, dry walled and the works.) I found out it was done for termite control (PROBABLY NOT THE RIGHT WAY)

Water was seeping through all of the holes, some had brittle wood corks that instantly disintegrated when touched other had been patched with cement that was also seeping

I had a basement water-proofing company come out and give me an estimate to put drain tiles and the works around the perimeter but I am not sure if this will remedy the problem now that I discovered some holes in the middle of the floor areas. (before i knew about all the holes)

What is the best solution to stop the water from ruining everything.

1. Rubber Cork and hydraulic cement and drain tiles and the works
2. Or will just rubber corks and cement solve the problem?
3. Any imput appreciated!!

Where were the termite holes drilled? Usually on the outside they are above grade and should not be a water issue. Those on the inside only penetrate the inner wall of the cement block leaving any waterproofing on the exterior in place.

But since the water proofing company is the only one that has seen what you've got they are probably the best to advise. We are just strangers on the Internet and only have the brief description and no photos that you provided.

99% of the time waterproofing is done on the outside, not the inside.
Grade sloping away from the foundation, gutters, no mulch or flower beds forming ponds against the foundation, may even need a french drain.
No sump pump in the basement?
It's very common to drill holes in the slab to treat for termites.

10 inches of rain in one day can overwhelm waterproofing systems, patching, etc.

Maybe a french drain with sump pump, battery back-up around interior of perimeter basement walls?
