Polymeric stabilization composition and method

Abstract

Embodiments of the present invention are methods and chemical compositions of polymers and crosslinking agents that are particularly suited to aggregate, including soil and other natural aggregates, stabilization via hydraulic application. The present invention is an improvement over existing methods as it provides effective stabilization for longer periods. The compositions, when in an aqueous solution and applied to soil or aggregate surfaces, penetrate the surface polymerize and form a crosslinked polymer film. Individual aggregate particles may bind to the polymer or may be entrapped by the polymer film. In the environment, the film is substantially resistant, in the near term, to biodegradation and natural, physical degradation due to weathering and exposure. The resultant polymer film and aggregate or bonded fiber matrix resists erosion by strong wind and heavy rain but readily allows seeds to germinate and grow. The crosslinked film is also substantially insoluble but nevertheless is biodegradable over the long term, ultimately decaying into harmless products. In addition a procedure for control of viscosity in the field application is described making possible cost savings by reducing the amount of required water for delivery.
