Kemsolid KSI 16000 Delivers 14m Deep Bentonite Cutoff Wall in Canada
Job Site Report
Kemsolid using TSM (Trench-Soil-Mixing) Technology in Cutoff Wall Project.
KSI 16000 Mounted on Komatsu 1250 LC Excavator I Val-d’Or, Canada.
Project Overview: Sealing Critical Infrastructure in Val-d’Or
In the mining region of Val-d’Or, Canada, a ground improvement contractor faced a demanding challenge: executing a high-integrity cutoff wall construction for a tailings pond. The goal was clear, achieve a reliable groundwater cutoff and long-term contamination barrier within mixed soil conditions (sand with clay / clay with sand) and medium hardness. To meet performance, environmental, and safety expectations, the contractor deployed the Kemsolid KSI 16000, an advanced solution engineered for deep soil mixing, dam sealing, and dam rehabilitation applications.
Why Kemsolid Cutter Soil Mixing Was the Right Choice
Compared to traditional methods such as sheet piling, slurry wall, diaphragm wall, the KSI system enabled continuous in-situ mixing with minimal soil displacement. This eliminated the need for extensive excavation, hauling, of-site mixing or temporary excavation shoring systems. The result? A cleaner, faster, and more sustainable bentonite slurry cuttoff wall.
Performance That Sets a New Benchmark
Mounted on a 120-ton Komatsu PC1250 excavator equipped with a double pump hydraulic system, the Kemsolid KSI 16000 delivered exceptional productivity over a 7-week timeframe. With a mixing depth of 14 meters and a width of 950 mm, the system achieved an average production rate of 48 m²/h, ensuring consistent panel quality and structural integrity throughout the cut off wall. Operating at 850 l/min oil flow and 220 bar pressure, the attachment maintained stable and uniform mixing, critical for cutoff wall construction in environmentally sensitive zones such as tailings ponds.
From Excavation Support to Long-Term Stability
This project highlights how Kemsolid technology could be used for a variety of foundation, ground improvement and soil stabilization projects such as complex foundation shoring systems like soldier beam, contiguous pile wall, or excavation support frameworks. Instead of multiple steps and materials, the KSI technology creates a homogeneous soil cement structure directly in the ground. This approach not only enhances sealing performance but also supports broader applications such as levee construction, dam rehabilitation, and groundwater cutoff systems.
The Future of Ground Improvement: Kemsolid Powered By KEMROC
For contractors seeking alternatives to conventional excavation shoring and deep foundation techniques, Kemsolid delivers a smarter solution. Whether replacing sheet pile walls, optimizing diaphragm wall execution, or eliminating the need for slurry trench operations, the KSI 16000 proves that cutter soil mixing is redefining efficiency in ground engineering.
Less excavation. More performance. Built for the future of foundation construction.
