Waterproofing a basement from the inside is usually done when the exterior of the building is not accessible.
- A channel of approximately 1ft wide is cut out of the concrete floor along the perimeter of the basement wall. The concrete is removed and the footing is exposed.
- Weeping tile is placed inside the channel and connected to either a floor drain or sump pump.
- Delta®-MS, a dimpled membrane, is applied to the entire wall from the bottom of the new trench up to the ceiling.
- Gravel is placed over top of the weeping tile to allow for the most efficient drainage.
- The remaining space in the channel is filled in with concrete and the job is complete.
