Tenocolumn method is a technology to stabilize soil by forming a column of soil hardened with a binder. This method has been applied in more than 33,000 projects (excluding residential houses), winning a high reputation for its quality and reliability


1. Overview of the Tenocolumn methods.

TENOCOLUMN is high-quality soil cement column produced by mixing cement slurry with in-situ ground soil. This method has experienced over 3,000 projects and received high evaluations.TENOCOLUMN is a soil cement that is applied by mechanical mixing method. Cement and mortar are sprayed into the soil by pressure pumps and then mixed with soil.

Mortar and cement are prepared with reasonable water and cement weight and then they are mixed by machine to ensure stable quality. Soil-cement has constructed which will be increased the strengthen and durability by automatic hard reaction, to ensure the superstructure long-term.

2. Characteristics of TENOCOLUMN

1. High Quality TENOCOLUMN is a high-quality and high-strength column through the efficient mixing and execution management.
2. Safety Construction Mechanization reduces dangerous works.
3. Speedy & Cost-effective Construction Economical and shorter-term completion results from prompt effect of improvement.
4. Multi-Application TENOCOLUMN is applicable to any soil condition like sandy soil, highly viscous clay, loam, unsolidified peat and so on.
5. Pollution-free Construction This low-vibration and low-noise method has less pollutive procedures and is free from secondary pollution.



3. Experimental data

As proof for the high quality of TENOCOLUMN, many tests have been carried out at project sites in Japan. All the test results are satisfactory with the quality and bearing capacity requirements. These achievements are resulting from our experienced construction methods and the optimization of cement mixing, corresponding to the soil conditions at project sites.

Actual size Tests

 Vertical load Testing:  over 100 cases

 Actual size strength Testing:  over 5 cases

 Transverse load testing:       over 5 cases                           

 Strength distribution Testing:    over 5 cases 

 Endurance testing:                  over 5 cases                           

 Mixing tests:                            many cases

4. Application of TENOCOLUMN

TENOCOLUMN method has been adopted in many construction projects as reliable building foundation. Nowadays, it is flexibly applied in various sites such as residential buildings, infrastructures ….

We are pleased that our method can help restore and reconstruction works after the earthquake caused unprecedented destruction in East Japan

* Application fields * Propose of Application
– Foundation – high-strength capacity of the foundation soils
– Road Embankment – preventing consolidation settlement
– Railway Embankment – preventing liquefaction 
– River Embankment – Keeping slip circle
– Port Construction – Keeping Soil
– Airport – Damping
– Sea Embankment – Stiffness of foundation
– Irrigation – Increasing intensity
– Retaining wall – Preventing movement of foundation
