Suppress overall deformation of the fill soil and achieve cost reduction with a low improvement rate! Examples of construction are also introduced with photos.
The "Low Improvement DMM Method" is a construction technique that places improved columns across the entire width in the transverse direction, which can suppress overall deformation of the embankment and allows for cost reduction by using a low improvement rate (by widening the spacing of the improved columns). When ground improvement is carried out at a low improvement rate, issues such as differential settlement between the improved and unimproved areas may arise, necessitating surface treatment as a countermeasure. For surface treatment, geosynthetics (Paralink) installation and shallow improvement methods are effective. [Selection of Geosynthetic (Paralink) Standards] ■ Determination of target differential settlement amount ■ -1 Calculation of proportional coefficient α ■ -2 Determination of tensile rigidity EA ■ Confirmation of tensile strength ■ Determination of required part numbers *For more details, please refer to the PDF materials or feel free to contact us.

Company information
"Simple is Best - Always question the truth and add even a little value." This is our mission. Through collaboration with the rapidly growing Macaferri (Italy) and its subsidiary Linear Composites (UK), which joined in June 2006, we aim to tackle challenges such as the development of geosynthetic parapets for soft ground stabilization measures and seismic design issues like liquefaction deformation suppression. We will continue to learn from everyone's wisdom and innovate daily.
