Ive been told to water my foundation and at the same time provide slopes to discharge water away from the building. Isnt this contradictory?
The goal here is to maintain consistent soil moisture content. Therefore, grades should be such that rainfall will continually flow away from the foundation, no matter how long and intense the storm might be. This minimizes the amount of moisture absorbed by soils under your foundation, limiting volumetric changes. When the climate turns drier, you can apply the correct amount of water to maintain consistent soil moisture content.
