We would like to introduce our developed "Non-Watering Snow Melting System." With traditional water-based snow melting, the raised parts of the road surface do not melt, but our system can melt everything. Additionally, when using groundwater with high iron content for watering, the pavement can become discolored with rust, but there are no such concerns with our non-watering method. It is a simple system that involves burying iron pipes to allow groundwater to flow through the concrete, but it incorporates many technologies developed from experiments, resulting in dramatic effectiveness. 【Features】 ■ No residual melting ■ No discoloration ■ Excellent freeze prevention effect ■ Significant reduction in accidents ■ Energy-saving *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Super Narrow Construction Method." This method is designed with a completely different concept from conventional ground improvement machines, featuring a compact construction machine that reduces costs and alleviates labor shortages, significantly contributing to your company's performance. All steel pipes apply a standard pressure reaction force of 12.74KN, allowing for monitoring of support capacity and enabling high-quality construction. Please feel free to contact us when you need our services. 【Features of the Method】 ■ One-man operation → One operator can handle everything from transportation to construction. ■ High-speed construction → Stable pressure allows for speedy construction. ■ Total weight loading method for construction machines → Support capacity can be managed from the monitor, achieving high-quality construction. ■ Proximity construction near structures → Pouring is possible very close to adjacent structures. ■ Bulk transport of machinery and materials → All equipment can be loaded onto a 3-ton truck. *For more details, please refer to the PDF materials or feel free to contact us.

The "Screw Press Liquefaction Mitigation Method" is a construction method suitable for residential areas, characterized by being vibration-free, low-noise, and having a short construction period. It is a hybrid method that simultaneously compresses sandy ground and dissipates pore water pressure, addressing liquefaction issues while also improving ground stability (increasing bearing capacity). Effectiveness tests were conducted over two years in collaboration with Nagaoka University of Technology at the prefectural land "Manyo Wharf" in Takaoka City, Toyama Prefecture, confirming its significant effectiveness. 【Features】 ■ An environmentally friendly method that does not use cement ■ Also improves ground stability (increases bearing capacity) ■ Vibration-free, low-noise, short construction period ■ Extremely low cost compared to existing methods ■ Generates very little drilling waste *For more details, please refer to the PDF materials or feel free to contact us.

The "Naro Power Method" is a ground improvement technique that involves driving numerous thin steel pipes down to the supporting ground to support residential buildings. All equipment is designed to be operated manually, allowing work to be conducted even in narrow spaces. After installation, a sampling load test is conducted to confirm whether the designed ground bearing capacity has been achieved, and if any deficiency in ground bearing capacity is observed, additional work will be carried out. By ensuring reliable quality control in this manner, we provide residential foundations that can withstand use for 50 to 100 years. 【Features】 ■ Recommended for the restoration of old houses ■ Sampling load tests are conducted ■ Suitable for narrow spaces where machinery cannot enter ■ Durability of 50 to 100 years *For more details, please refer to the PDF materials or feel free to contact us.

• Ground foundation construction method

The "Screw Press Steel Pipe Insertion Method" is a foundation method for mega-solar installations that adapts to all types of land. By performing pre-drilling, it enables construction on sandy soils, clayey soils, and gravelly ground. Additionally, since thick steel pipes are erected vertically, braces are unnecessary, allowing for wider spacing between piles and achieving overall cost reduction for the framework. During removal, the steel pipes can be sold for more than the removal costs, providing an advantage in asset value compared to methods that incur removal and waste disposal costs, such as concrete gravity foundations or concrete piles. 【Features】 ■ Foundation method using winged steel pipe rotary insertion ■ Asset value exceeding removal costs ■ Adaptable to various ground conditions ■ Achieves cost reduction ■ High quality, high precision, low noise *For more details, please refer to the PDF materials or feel free to contact us.

GranTech Co., Ltd. is seeking franchisees for the high-quality yet low-cost ground improvement method, the "Screw Press Method." This method uses a special screw equipped with a dedicated ground improvement machine, employing the principle of a screw nail for excavation. It generates a compaction phenomenon around the excavation area, creating a stronger foundation. While the cost is lower than conventional methods, it allows for orders at a price with added value. This new business with high added value will contribute to the development of your company. 【Features】 ■ Stable revenue secured through advanced patented technology ■ Excellent cost competitiveness ■ Significant contribution to the environment ■ Maintenance of high quality in ground improvement ■ Ultra-low cost in liquefaction mitigation work *For more details, please refer to the PDF document or feel free to contact us.

The implementation area is currently expanding sequentially, focusing on the Hokuriku and Kanto regions! The screw press method improves ground bearing capacity and achieves a "seismic-resistant ground." It creates a compaction phenomenon by pushing the surrounding soil with the volume of the screw itself, resulting in a stronger foundation. Since there is no generation of excavated soil, construction time is significantly reduced compared to conventional methods, allowing for low-cost construction. Additionally, there is no need for soil treatment that would become industrial waste, greatly contributing to environmental conservation. 【Features】 ○ Zero excavated soil ○ Significant reduction in construction time and costs ○ Environmentally friendly low-carbon ground improvement method ○ Pile formation using thinned wood or crushed stone is possible ○ Crushed stone piles are strong against earthquakes and significantly reduce liquefaction phenomena For more details, please contact us or download the catalog.

The "Screw Press Method" is a ground improvement technique that enhances soil bearing capacity, creates earthquake-resistant ground, and is an environmentally friendly low-carbon ground improvement method. The crushed stone columns created by this method compact the entire ground through pressure, and even if shear occurs, it has little effect on strength, while also effectively attenuating seismic waves, protecting your valuable home from earthquakes. It demonstrates tremendous effectiveness in liquefaction countermeasures by strongly compacting the ground and dissipating pore water pressure through highly permeable piles. This method resolves the concerns and worries associated with traditional ground improvement work, creating a reliable foundation to support buildings. 【Features】 ■ Significant reduction in construction time and costs ■ Environmentally friendly low-carbon ground improvement method ■ Capable of forming piles from thinned wood or crushed stone columns ■ Excavation method with zero excavation residual soil ■ Crushed stone columns are strong against earthquakes and significantly reduce liquefaction phenomena *For more details, please refer to the PDF document or feel free to contact us.
