Abstract
A method is provided for waterproofing a foundation in which a minimal amount of debris is generated. The method provides for selecting a first limited area of excavation of a floor along a wall. A tunnel is dug laterally below the floor to a location remote from the area of excavation for receiving a drainage pipe underneath the floor. A narrow channel is further excavated within the floor along the wall for receiving accumulated moisture leaking in from the wall. The channel directs and drains the moisture towards the excavated area in the floor and the drainage tunnel. With the limited amount of excavation provided by this method, the amount of concrete to be removed is substantially reduced.
