Chapel Hill, NC – Concrete Uprising, a North Carolina based concrete leveling and soil stabilization company, recently achieved remarkable success in stabilizing an elevator pit plagued by severe water intrusion. Utilizing the state-of-the-art NCFI Terra-Lok™ 24-120 Single Component Geotechnical Polyurethane, the company effectively resolved the water infiltration issue, resulting in a fully sealed elevator pit and an immensely satisfied customer.
Elevator Pit Stabilization with Terra-Lok Single Component PolyurethaneThe elevator pit presented a daunting challenge as it was inundated with an astonishing 4 to 5 feet of water. This excessive water accumulation not only jeopardized the structural integrity of the elevator shaft but also led to the development of mold on the bottom floor due to the excessive moisture. Concrete Uprising swiftly identified the problem and embarked on a comprehensive approach to stabilize the pit.
Understanding the urgency of the situation, Concrete Uprising initiated the stabilization process by promptly dewatering the elevator shaft. Recognizing the magnitude of the water ingress, the company had to utilize two pumps instead of one to effectively remove the substantial volume of water from the pit. By meticulously dewatering the shaft, the team created a conducive environment for the subsequent stabilization measures.
Mechanical Packer for single component injectionConcrete Uprising then turned to the cutting-edge NCFI Terra-Lok™ 24-120 Single Component Polyurethane for an effective solution to the water intrusion issue. Renowned for its exceptional sealing capabilities, this geotechnical polyurethane system proved to be the ideal choice to address the problem.
To ensure a thorough application, mechanical packers were strategically placed to inject the Terra-Lok™ 24-120 behind the cinder block walls surrounding the perimeter of the elevator shaft. This specialized polyurethane system, designed specifically for water infiltration problems, effectively sealed the gaps and crevices, preventing any further water ingress into the pit.
Given the substantial volume of water present, a catalyst was introduced to activate the Terra-Lok™ 24-120. This additional step was necessary to ensure optimal performance and expedite the sealing process. Injections were made at 3-foot intervals at a height of 4ft along the walls, and on a 3ft gridded pattern on the earthen floor, creating a comprehensive barrier against water intrusion. This meticulous approach ensured a watertight seal, effectively safeguarding the elevator shaft from further water damage.
