KSI 12000 & KSI 16000 Soil Mixing Attachments
Hammer & Steel offers the Kemsolid KSI 12000 and KSI 16000 — powerful, high-performance trench-soil mixing (TSM) attachments engineered for producing continuous, in-situ soil-cement walls. Ideal for retaining walls, diaphragm walls, excavation sealing, and foundation improvement, these attachments integrate seamlessly with large excavators and drilling rigs.
What Sets Kemsolid Attachments Apart?
- Continuous Mixing - Unlike segmented diaphragm wall systems, KSI attachments create uniform, continuous structures that eliminate misalignment and improve consistency.
- Deep Mixing - Capabilities KSI 12000 supports mixing depths up to 39 feet; KSI 16000 reaches depths up to 52 feet — adaptable to project needs with modular blade lengths.
- Versatile Applications - Perfect for trench shoring, dam and dyke sealing, enclosing contaminated sites, and stabilizing soil for road and rail construction.
- Efficient & Environmentally Friendly - High production rates (300+ linear ft/day depending on soil conditions) and reduced CO₂ emissions through advanced twin-blade (KSI TWIN) and multi-blade (KSI HYDRA) variants.
