GT Spiral Pile: A friction foundation pile that can also be constructed without heavy machinery.

Firm support even on weak ground! Foundation piles that can be completed on the same day in weak or narrow ground, without the need for concrete.

Are you struggling with the sinking of concrete foundations on weak ground, or the design and construction in mountainous areas and narrow sites where heavy machinery cannot enter? With "GT Spiral Piles," you can reliably support loads even on weak ground with excellent friction resistance. There is minimal excavation and soil disposal, and even long piles can be installed in just a few minutes. Since there is no curing period, you can immediately transition to building above it. Additionally, it accommodates flexible designs to avoid underground pipes, dramatically reducing the construction burden on site. Strong support to prevent sinking on weak ground Even in extremely weak ground like marshland or reclaimed land, it exhibits high friction resistance to reliably support loads as foundations for structures like floating decks. Flexible response in sites where heavy machinery access is difficult In narrow areas and mountainous regions where large machinery cannot enter, installation is possible using manual labor or small pile drivers. Flexible response to underground pipes Even if there are buried pipes at the foundation location, it is possible to design piles and bases that avoid interference.
