Abstract
Minor slides in a geologic exploratory trench are stabilized by applying a ater diluted vinyl acetate-ethylene copolymer emulsion to the trench walls. Although the resulting emulsion and sand crust provides no structural support, it provides a surface cohesion which effectively stops all minor sliding and permits normal engineering logging to proceed.
Claims3
A method of stabilizing unconsolidated sand and gravel in a geologic exploratory trench wall comprising the step of:
- spraying a vinyl acetate-ethylene copolymer emulsion to the trench wall surface to form a cohesive clear emulsion-sand crust, so as to allow for visual observation of the underlying trench wall.
