I am building an ICF basement, dimple membrane on the outside and standard weeping tile next to the footing. The basement is split with one area 2 feet lower than the other. Poured in the fall and was uninsulated in the winter. Weeping tile did not thaw until June. Some (presuambly) snow melt got into the lower area. Is not drying. Dug a hole and found water starting at about the same level as the bottom of the weeping tile. No internal weeping tile. Does anyone think this water is a problem? Should I install an internal weeping tile system? Will this water just leave over time? Changes a little with rain (up approx 3/4 of an inch). No one here seems to know anything about this.

Is it not code in your area to put a perimeter drain on the inside and outside? |

If you have a relatively high water table in your location, as I do, you will have water problems at the transition area your basement floor levels. Unless you provide some type of drainage system around this internal footer. During the 'wet months', the ground water saturates the soil under your basement slab. If your interior stem wall is not waterproofed and drain tile installed on the 'outside' of it, then the hydrostatic pressure will cause this ground water to seep over, under, around, and through the stem wall into the lower level of the basement.
Several years ago, tri-level home designs were popular in my part of the world. I have inspected and repaired many of these with water issues in the lower level. In every case the worst areas of leakage were along the transition walls between the lower levels and the middle levels of the plans.

No. When I discussed the idea of using a product for the footning that gives interior and exterior weeping tile, my contractor said no body uses it, its not necessary.

The whole lower area seems wet. What if I put a weeper around the interior footing and in the middle of the space (run a couple channnels, put in some weeper and crushed rock and run to a sump). Will this "encourage" water to migrate into the space. I read that it should relieve some of the hydrostatic pressures on the outside wall.

Sorry, I answered my own reply. It is not just the transition that is wet, the whole thing is wet. Please see the response to myself for a thought. Thanks

Yes,
Water runs downhill, so to speak. Give it an alternative, easier route and it will follow.
Your plan is doable. |
