Chemical Method and Composition for Soil Improvement

Abstract

A composition for chemical soil improvement includes a uniform molecular structure synthetic fluid with a substantially uniform molecular structure, a pour point depressant, polyisobutylene, and synthetic fibers, and various combinations thereof, wherein the compotion creates an impermeable layer.

What is claimed is: 
     
         1 . A method for chemical soil improvement, utilizing a composition including a synthetic fluid and synthetic fibers, the method comprising the step of:
 creating an impermeable layer over an in situ soil by applying the composition to the soil.   
     
     
         2 . The method of  claim 1 , wherein the synthetic fluid is synthetic isoalkane, and the synthetic isoalkane is about 50% to about 95% by weight. 
     
     
         3 . The method of  claim 1 , wherein composition further comprises a binder, wherein the binder is chosen from the group comprising a carboxylic acid, an ester, and a thermoplastic polyolefin. 
     
     
         4 . The method of  claim 3 , wherein the thermoplastic polyolefin is chosen from the group comprising: polyethylene, polypropylene, polybutene, polyisobutylene, polyisoprene, and their copolymers. 
     
     
         5 . The method of  claim 1 , wherein the synthetic fibers are polypropylene, are about one-quarter inch to about three inches in length, and are chosen from the group comprising standard tape fibers, fibrillated fibers, and decomposing fibers. 
     
     
         6 . The method of  claim 1 , wherein the composition further comprises a pour point depressant, wherein the pour point depressant is chosen from the group comprising acrylic, acrylic copolymers, polymethacrylate, ethylene vinyl acetate copolymers, alkyl esters of unsaturated carboxylic acids, alkyl phenols, alpha olefin copolymers, and polyalkylmethacrylate. 
     
     
         7 . The method of  claim 6 , wherein synthetic fluid is synthetic isoalkane and the synthetic isoalkane is about 80% to about 95% by weight of a mixture of the synthetic isoalkane and the binder. 
     
     
         8 . The method of  claim 6 , wherein the binder is chosen from the group comprising a carboxylic acid, an ester, polyisobutylene, and a thermoplastic polyolefin. 
     
     
         9 . The method of  claim 6 , wherein the composition further comprises an emulsifier. 
     
     
         10 . The method of  claim 6 , wherein the synthetic fibers are polypropylene, are about one-quarter inch to about three inches in length, and are chosen from the group comprising standard tape fibers, fibrillated fibers, and decomposing fibers. 
     
     
         11 . The method of  claim 6 , wherein the synthetic fluid meets EPA standards for offshore drilling.
