Summary of TNF construction method

By integrating the ground reinforcement layer, the foundation, and the slab, the load from the column can be transferred to not only the foundation under the column but also to the supporting soil through the reinforcement layer from the slab surrounding the foundation.
In addition, when the bottom of the reinforcement layer, the surface touching the supporting layer, is in a grid pattern, the load is transferred to the ground in a way that makes energy work to hold the soil at the hollow part and prevent it from going out.
It will be stable as the way the load is transferred supports the building.
We call it the "TNF enclosure effect" and are one of the biggest features of TNF construction method.

TNF construction method usually does not have underground beams. The foundation and the concrete slab are directly installed to the reinforcement layer which is made in a grid pattern.
The load of the building can be efficiently transferred onto the supporting soil because the reinforcement layer, the foundation, and the slab are integrated.
Conventionally, the pile foundation system that uses the strong lower layer as the supporting layer was the main stream when the surface layer is soft and weak, but with the TNF construction method, a low cost foundation without piles can be made because it can use the surface layer as the supporting layer.
