Spraying Portland Cement on the surface of slopes is an effective device against erosion, and the efficacy is enhanced by the surface treatment by means of chemicals, fluorides, for example, ammonium silicofluoride, ammonium bifluoride, zinc silicofluoride and magnesium silicofluoride. The treatment with fluorides has been proved as effective in all the test experiments, and the repetition of the spray has been found to magnify the effect though it will cost somewhat higher.
