HIGH VOLUME INDUSTRIAL LEAK INJECTION CASE STUDY

Project:      Wolverine Tube Expansion Project Water Leak Repair
Location:    Decatur, Alabama
Owner:       Wolverine Tube

 

Located on the banks of the Tennessee River in Decatur, Alabama, Wolverine Tube, Inc. is one of the largest copper tube and pipe manufacturers in the country.

While proceeding with an expansion project, it was required that a 40 foot deep pit had to be installed.  After removing 20 feet of soil, bedrock was encountered and the remaining 20 feet had to be blasted out.

Soon after all of the rock was removed, a water leak developed within the bedrock wall and began to fill the pit, preventing any further construction.  The volume of the leak was estimated at approximately 300 gallons per minute, making it impossible to set form or pour concrete.

The Wolverine Engineering Department contacted Jean’s Waterproofing, Inc. (JWI) to provide a solution to their problem.  After visiting the site, JWI proposed that a drill rig be used so that 3.5 inch holes could be drilled approximately 5 feet from the edge of the pit and directly above where the leak was spilling in below.  The holes were drilled to intersect the water vein.  Slotted PVC pipes were then installed as sleeves into the drilled holes.  JWI would then install an inflatable packer, specially designed for use with two-component resin systems, down to within 2 feet from the base of the drilled hole and inflate it to keep it in place.

A two-component, polyurethane injection resin was then pumped using a 1:1 ratio using 2 rotor-stator pumps.  As the resin exited the packer within the hole, the A & B components mixed together and began to cure within seconds.  After 2.5 days of drilling and pumping, the leak was completely sealed
