New technology for shortening construction periods and reducing building costs! An explanation of the TNF method that overturns the conventional wisdom of traditional foundation construction methods!

This document provides a detailed introduction to the new technology "TNF Method" for shortening construction periods and reducing building costs. This method achieves a low-cost foundation that does not require piles. Typically, there are no underground beams, and the foundation and slab concrete are directly poured onto the improved layer shaped like a grid. We provide a detailed explanation of the "construction sequence," "cost comparisons by type of work," and "construction achievements," along with diagrams and photographs. We encourage you to read it. 【Contents】 ■ Why is foundation work necessary in construction? ■ What is the current situation regarding this? ■ What are the current issues? ■ Proposals for new construction and extensions ■ What is the TNF Method? *For more details, please refer to the PDF document or feel free to contact us.
