Method for Installing a Helical Pier with Polyurthane Resin Grout

Abstract

A method for installing a helical pier using a polyurethane resin grout that results in a support structure capable of bearing heavy loads and exhibiting high lateral strength which is also nontoxic and non-hazardous to the environment

What is claimed is: 
     
         1 . A method for installing a helical pier with polyurethane resin grout, the method comprising the steps of:
 (a) installing said helical pier in a target location;   (b) filling the area adjacent to said helical pier with a polyurethane resin grout; and   (c) allowing said polyurethane resign grout to cure.   
     
     
         2 . The method for installing a helical pier according to  claim 1 , further comprising, before step (b): drilling a borehole at said target location. 
     
     
         3 . The method of installing a helical pier according to  claim 1 , further comprising, before step (b): inserting one or more injection tubes at said target location and blowing said polyurethane resign grout near the helixes of said helical pier.
