Slurry-based mechanical mixing block ground improvement method capable of removing underground obstacles and unsuitable soil for improvement.
The "Elmad S Method" is a construction technique that creates a block-like homogeneous ground improvement body by using cement-based solidification materials to treat soft ground through fluidization. By utilizing a mixing device (such as a bucket mixer) powered by the hydraulic system of an excavator, it is possible to efficiently mix the local soil. Since it is based on a general-purpose excavator, it can adequately handle construction in adverse conditions, such as areas with restrictions on height or undercut beams. 【Features】 ■ Excavating and removing soil down to the supporting ground allows for visual confirmation of the condition of the supporting ground. ■ Ensures secure anchoring to the supporting layer. ■ Uses appropriate attachments for mixing based on soil type. ■ Solidification material can be evenly distributed in the soil. ■ Achieves homogeneous strength development. *For more details, please download the PDF or contact us.

basic information
【Other Features】 ■ It is possible to display the mixing degree and improvement trajectory of the modified body during construction. ■ As a supervisor, it is possible to observe the previously unclear mixing and stirring conditions in real-time. ■ Samples can be collected immediately after construction using either a head sampler or a deep sampler. ■ Homogeneity can be evaluated using uniaxial compressive strength. ■ Easy to collect, making it economical. ■ No extraction after construction, so it does not affect subsequent work processes. ■ Similar to deep mixing treatment methods, management is also possible with head cores and full-length cores. *For more details, please download the PDF or contact us.

Company information
Elf Corporation has been working as a consultant for foundation design of structures since its establishment, striving to propose the most suitable construction methods when selecting foundation techniques. In cases where the direct foundation is too deep and the pile foundation is too short, we developed the Elmad method and Elcolumn method as techniques to bridge the gap between direct foundations and pile foundations. We will continue to make efforts to propose new construction methods in the future.
