Concrete is naturally basic (has high pH). Ufer observed this meant that it had a ready supply of ions and so provides a better electrical ground than almost any type of soil. Ufer also found that the soil around the concrete became "doped", and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced. The concrete enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, which also helps t… suzuki tf125 specsWeb1 day ago · The FAA is adopting a new airworthiness directive (AD) for certain ATR—GIE Avions de Transport Régional Model ATR42–500 and ATR72–212A airplanes.
