"Shallow improvement" that supports the entire ground surface of the building without using piles.
The "TNF Method" is a low-cost special foundation construction method that integrates the slab and building foundation with improved ground using solidifying materials, supporting the building across the entire improved ground surface without the use of piles. By dispersing soil stress in multiple directions, it suppresses one-directional extrusion of the soil. It allows for construction while protecting historical heritage and other underground assets. Additionally, it significantly reduces the use of materials such as rebar, concrete, and formwork. 【Features】 ■ Suppresses differential settlement ■ No uplift steps that occur in pile-supported buildings ■ The improved ground shields against surface outflow of soil and mitigates liquefaction directly beneath the building ■ Minimal impact on underground natural environments such as groundwater ■ Protects underground buried objects ■ Reduces CO2 emissions *For more details, please refer to the PDF materials or feel free to contact us.
