Biodegradable woven burlap silt fence for trenchless and trench instalation and method of installing the same

Abstract

A cost effective, efficient, and easy to implement biodegradable woven composite burlap silt fences with stabilizing fins having a bury depth indicator. The silt fence comprises plurality of spaced stakes; and a burlap geotextile with a weight greater than 15 oz per square yard and less than 50 oz per square yard comprising one of i) a single layer burlap material and ii) a composite burlap material having multiple burlap layers. A trenchless method of installation includes using an apron on a lower portion of the geotextile and driving the plurality of spaced wooded or metal stakes into the ground until the integral ground engaging apron is flush with the ground; and staking the ground engaging apron to the ground with staking elements.

What is claimed is:

         2 . The silt fence according to  claim 1 , further including a belting strip folded over the top of the bulap geotextile and secured thereto. 
     
     
         3 . The silt fence according to  claim 2 , wherein the belting strip is a 4″ wide burlap strip sewn to the geotextile. 
     
     
         4 . The silt fence according to  claim 2 , further including stabilizing fins on selective stakes formed by a plate secured thereto. 
     
     
         5 . The silt fence according to  claim 4 , wherein in the burlap geotextile is a single layer burlap material formed of 17 oz burlap. 
     
     
         6 . The silt fence according to  claim 4 , wherein in the burlap geotextile is an asymmetrical biodegradable composite burlap geotextile. 
     
     
         7 . A trenchless method of installing a silt fence for erosion, sediment and pollution control, comprising the steps of:
 Providing a silt fence bundle comprising a plurality of spaced wooded or metal stakes and a burlap geotextile with a weight greater than 15 oz per square yard and less than 50 oz per square yard comprising one of i) a single layer burlap material and ii) a composite burlap material having multiple burlap layers, with the geotextile coupled to the spaced wooded or metal stakes and including an integral ground engaging apron;   Driving the plurality of spaced wooded or metal stakes into the ground until the integral ground engaging apron is flush with the ground; and   Staking the ground engaging apron to the ground with staking elements.   
     
     
         8 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 7 , wherein the silt fence bundle further includes a belting strip folded over the top of the bulap geotextile and secured thereto. 
     
     
         9 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 8 , wherein the belting strip is a 4″ wide burlap strip sewn to the geotextile. 
     
     
         10 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 8 , further including stabilizing fins on selective stakes formed by a plate secured thereto. 
     
     
         11 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 10 , wherein in the burlap geotextile is a single layer burlap material formed of 17 oz burlap. 
     
     
         12 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 10 , wherein in the burlap geotextile is an asymmetrical biodegradable composite burlap geotextile. 
     
     
         13 . The trenchless method of installing a silt fence for erosion, sediment and pollution control according to  claim 7 , wherein the staking elements include staples and wherein the staples include a row of staples at a leading end of the apron located at a distal end of the fabric. 
     
     
         14 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 13 , wherein in the burlap geotextile is a single layer burlap material formed of 17 oz burlap. 
     
     
         15 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 13 , wherein the silt fence bundle further includes a belting strip folded over the top of the bulap geotextile and secured thereto. 
     
     
         16 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 15 , wherein the belting strip is a 4″ wide burlap strip sewn to the geotextile. 
     
     
         17 . The trenchless method of installing a silt fence for erosion, sediment and pollution control, according to  claim 16 , further including stabilizing fins on selective stakes formed by a plate secured thereto. 
     
     
         18 . A silt fence configured for trenchless installation comprising:
