I'm trying to understand a situation that occurred in my office. This is not my area of expertise, but I'd still like to know why the decision was made. In a nutshell: someone specified water proofing, the contractor pulled it in VE and replaced it with a vapor barrier. From the geotechnical report, there's no issue with the water table. However, there a small 3' depressed area, SOG, and the decision was to fight for waterproofing in that area. Why? I was told rain water or sprinklers would produce water that would exert hydrostatic pressure on the slab. I get the walls, but how can water flow down and then push up on the slab? Like the elevator, there a perforated pipe lining the 3' wall. If the pipe wasn't there, would that be an issue? I'm having trouble grasping the physics behind this hydrostatic pressure under the slab. How can there be a head pushing up? Im totally missing something here. I appreciate your thoughts.
