The KSI series injection machines were developed in collaboration with a leading German foundation engineering company and form the basis for the innovative KEMSOLID process. This groundbreaking soil consolidation technology involves the use of a KSI mixing blade attached to a hydraulic excavator, which penetrates the soil and mills a cement suspension into insufficiently load-bearing soils. This process results in the formation of a homogeneous, waterproof, and frost-proof earth concrete, which significantly improves the load-bearing capacity of the soil.

The KSI machines are highly versatile and can be adapted to different soil conditions and desired load-bearing capacity by using different cement formulations. The KSI mixing milling machines come in two sizes and various blade lengths, suitable for excavators weighing between 40 and 120 tons.

The KSI 7000 drive unit is designed for mixing depths of 5, 6 or 7 meters, while the larger KSI 12000 model can reach depths of 6, 8, 10 or 12 meters. Both models can be upgraded with a rotation module, providing even greater flexibility and precision.

With the KEMSOLID process and KSI series injection machines, excavation projects can achieve higher levels of soil stability, increased load-bearing capacity, and improved durability, all while reducing the environmental impact of traditional soil stabilization methods.
