Bricks, Masonry, Asphalt and Concrete - leaking basement

Folks, the daughters basement on their 2 year old house has sprung a leak. The culprit seems to have been a large pooling of rain water under the deck, up against the foundation. Some people have said that, no matter how well their concrete had been waterproofed, that standing water will eventually permeate it. This doesn't sound right, and that's why I'm asking for some expert opinions.
Does it make sense to rip out the interior drywall to trace the leak, or is the only solution to excavate and re-waterproof the walls from the outside?
Thanks in advance for your advice.

Tearing out the inside doesn't help much except to repair water damage. Water has the ability to travel horizontally and even upward (in the case of underground). you have to look to the source, not just find a leak.

The first thing to do is get rid of the obvious - The water pool is staring at you is the first. Slope the soil away from the house, cover it with plastic and weight it down (landscape rock?) to keep it in place.

The mose effective and least costly method to have a dry basement in an existing home it to have proper drainage to move the water away. This includes gutters, downspout extensions (8 - 10') and positve drainage (away from the house). Having a pool adjacent to the house is just asking for trouble.

There is no such thing as a waterproof basement. The many that are bone dry have sufficient waterproofing to withstand the moisture that is permitted around the foundation. Even a "waterproof" ship leaks some water.

You mentioned that the basement was waterproofed. There are many versions of waterproofing. They range from spraying on some sort of mystical miracle cure to proper subsurface systems like interior and exterior drain tile with pumps. What was done to insure a dry basement in her case?
