TENOCOLUMN ECO MethodUsing the TENOCOLUMN ECO Method to reduce construction costs.
About The TENOCOLUMN ECO Method
- developed with the aim of reducing foundation construction costs and decreasing environmental load.
- High-strength column method which is an evolution of the existing TENOCOLUMN method.
- How can conventional technology be used to increase the high strength of improved soil? Using large amounts of solidification material ⇒ Increase in construction expenses (material expenses) and generated remaining soil
- Achieved high strength by using the special admixture Herasel.
Ultra-high concentration with a water/solidifying material ratio (W/C) of 45% to 50% in the solidifying material liquid.
Reduction of residual soil generated during construction, high strengthening of improved soil, and achievement of construction efficiency. - Through this method, we expect a reduction in the number of columns and a decrease in the foundation footing area.
- Makes it easy to achieve stable construction (securing strength) even with organic soil and loam.
Reducing the number of columns
Reduction of basic footing area
