Penn Forest Dam Replacement Contract IV Penn Forest Township Scranton, Pennsylvania Back to Project List High Mobility Grouting Nearly 20% of the grouting work was performed on a near vertical slope. Project Overview: Layne GeoConstruction installed a deep grout curtain for the Penn Forest Dam Replacement project. Approximately 400 holes were drilled, to depths exceeding 200 feet. The drill holes were washed, pressure tested and grouted conventionally with cementitious grouts. Approximately 60,000 linear feet of drilling was completed, with verification holes completed using NQ-2 style core equipment. The project was unique and challenging, in that 20% of the work was completed on a near vertical slope, using CP-style drills. Additionally, the accelerated project timetable contributed to the challenge, as Layne employed 40 personnel working around the clock, seven days per week.     Value of Work Performed: $3,100,000 Project Duration: 6 months Project Completion Date: November 1997 Project Reference: Project Owner City of Bethlehem, PA
