Should lateral pressure from groundwater be considered when designing foundation walls in competent rock? Let's say rock is immediately below existing ground surface and there will be a 30-foot-deep excavation and the measured groundwater is 10 feet below ground surface. So the competent rock 20 feet above the bottom of excavation is submersed in groundwater. And the groundwater is only a few molecule thick between competent rock and new foundation wall.
