High Grip Grout Method

High Grip Grout Method

[NETIS Registration] Chemical injection method that reduces injection loss during construction.

The High Grip Grout Method is a grouting technique that enhances the prevention of chemical leakage from drilled holes using ground packers, ensures a large source of chemical penetration with special sealing materials, and improves injection efficiency through a centralized management system for chemical injection. *NETIS Registered Technology: CB-180028-A [Ground Packers] Ground packers are designed with a structure that prevents the leakage of filling materials (a double structure of fabric and rubber), which suppresses shrinkage after the expansion of the ground packer and enhances the adhesion between the drilled hole and the ground packer. This prevents the leakage of chemicals from the drilled hole. [Special Sealing Materials] The sealing materials use a special substance that fluidizes when reacting with chemicals, protecting the hole walls during drilling and ensuring a large penetration area during chemical injection. This allows for a reduction in injection pressure and the creation of a large-diameter modified body with a diameter of 2.5 meters. [Injection Management System] The system used in this method can simultaneously manage multiple chemical injection pumps (16 points). This improves the efficiency of injection and achieves cost reduction through shortened processes. *For more details, please refer to the catalog or feel free to contact us.

Sand Pressure Infiltration Static Compaction Method "SAVE-SP Method"

Sand Pressure Infiltration Static Compaction Method "SAVE-SP Method"

Using ultra-compact construction machinery! This is a new concept in compaction methods that utilizes sand with added fluidity.

The "SAVE-SP Method" is a liquefaction countermeasure technique that uses ultra-small construction machinery to inject sand, which has been made pumpable, into the ground through a rod, thereby compacting the soil. It is possible to perform construction in narrow spaces and to compact the ground directly beneath existing structures. The sand, which has been mixed with a fluidizing agent and made pumpable (fluidized sand), is injected into the ground from the rod that has been driven to a specified depth, compacting the surrounding soil. The fluidity of the pumped sand disappears due to dewatering during discharge and the action of the added slow-acting plasticizer, forming good ground conditions. 【Features】 ■ Uses ultra-small construction machinery ■ Capable of liquefaction countermeasures directly beneath existing structures ■ Vibration-free and low noise ■ Excellent cost-effectiveness ■ Environmentally friendly construction method ■ October 2014, National Institute for Land and Infrastructure Management, Construction Technology Review Certificate No. 37 *For more details, please refer to the PDF document or feel free to contact us.

Columnar ground improvement method

Columnar ground improvement method

It is possible to carry out construction even in narrow spaces by using small machines that are vibration-free and noise-free.

This technology involves pumping a milk-like cement-based solidifying material (slurry) into the ground while excavating, mixing, and stirring with an excavator equipped with mixing blades to create a strong columnar improvement body. Using small machines that operate without vibration or noise allows for construction even in narrow sites. Additionally, it can be applied in areas with high groundwater levels or highly collapsible ground. It can be used for a wide range of applications, including building foundations, measures against settlement and sliding of embankments, retaining walls, and water-stopping walls. 【Features】 ■ Creates a strong columnar improvement body ■ Can be applied in areas with high groundwater levels or highly collapsible ground ■ Capable of forming improvement bodies with diameters ranging from 500mm to 1,800mm ■ Construction depth can reach up to 15m *For more details, please refer to the PDF materials or feel free to contact us.

Surface ground improvement method

Surface ground improvement method

The depth of improvement is about 2 meters from the ground surface! It is mainly used in ground conditions where the soft layer is thin.

This technology involves spraying cement-based solidifying materials onto soft soil, mixing and stirring it with the original ground soil, and utilizing the hydration hardening reaction of the improvement agent to stabilize the soil. When large vehicles run directly on soft ground, their tires quickly sink, making it impossible to move. However, by laying down steel plates or gravel, they can move freely. Similarly, by creating a hard artificial layer on the surface of soft ground, surface ground improvement supports buildings. The depth of the improvement extends to about 2 meters from the ground surface. 【Features】 ■ Spraying cement-based solidifying materials on soft soil ■ Utilizing the hydration hardening reaction of the improvement agent ■ Stabilizing the soil *For more details, please refer to the PDF document or feel free to contact us.

Introduction to the ground improvement method "Elmad S Method"

Introduction to the ground improvement method "Elmad S Method"

Slurry-based mechanical mixing block ground improvement method capable of removing underground obstacles and unsuitable soil for improvement.

The "Elmad S Method" is a construction technique that creates a block-like homogeneous ground improvement body by using cement-based solidification materials to treat soft ground through fluidization. By utilizing a mixing device (such as a bucket mixer) powered by the hydraulic system of an excavator, it is possible to efficiently mix the local soil. Since it is based on a general-purpose excavator, it can adequately handle construction in adverse conditions, such as areas with restrictions on height or undercut beams. 【Features】 ■ Excavating and removing soil down to the supporting ground allows for visual confirmation of the condition of the supporting ground. ■ Ensures secure anchoring to the supporting layer. ■ Uses appropriate attachments for mixing based on soil type. ■ Solidification material can be evenly distributed in the soil. ■ Achieves homogeneous strength development. *For more details, please download the PDF or contact us.

Ground improvement method "DCI Multi-Point Injection Method"

Ground improvement method "DCI Multi-Point Injection Method"

Construction is possible near and directly beneath existing structures! This chemical grouting method does not require regular visual inspections or displacement measurements, allowing for minimal personnel involvement in the construction process.

The "DCI Multi-Point Injection Method" is a ground improvement technique that can suppress displacement by injecting at low pressure and low discharge. Although the injection speed per pump is low (1 to 6 liters per minute), rapid construction is possible through simultaneous multi-point injection (32 connections). According to the injection pressure, each pump is mechanically and automatically controlled, and flexible injection pipes are consolidated to minimize the occupied area. 【Features】 ■ Construction is possible near and directly beneath existing structures. ■ Rapid construction is possible through simultaneous multi-point injection (32 connections). ■ Construction in narrow areas is possible with a dedicated system (DCI system). ■ Each pump is mechanically and automatically controlled according to the injection pressure. ■ Flexible injection pipes are consolidated to limit the occupied area. *For more details, please refer to the PDF materials or feel free to contact us.
