Application Areas

Dedicated to providing efficient, reliable, and environmentally friendly grouting, leak-sealing, and structural reinforcement system solutions for geotechnical engineering and major infrastructure construction worldwide.

Tunnel and Underground Engineering Field

Tunnel and Underground Engineering Field

During tunnel excavation, it is often necessary to pass through fault fracture zones, water-rich and weak rock formations, or areas of high stress. The fissure widths in such surrounding rocks typically range from 0.01 mm to 0.1 mm, accompanied by high groundwater pressures, which greatly increase the risk of serious hazards such as sudden water and mud bursts at the face and instability of the surrounding rock.

Mining and extraction field

Mining and extraction field

Mine shafts in coal and metal mines often pass through water-rich sand layers, fault fracture zones, and mined-out areas, making them highly susceptible to sudden water bursts, sand surges, ground subsidence, and abnormal gas emissions—serious safety hazards.

Oil and Gas Sector

Oil and Gas Sector

During oil and gas drilling, it is common to encounter fluid loss in fractured reservoirs and wellbore instability. As oilfields enter the high-water-cut stage, they also face development challenges such as water breakthrough and declining recovery rates.

Hydropower and water conservancy field

Hydropower and water conservancy field

The dam body and foundation are subjected to long-term water infiltration, often resulting in minor crack leakage and seepage within the reservoir area, which can compromise the safety and service life of the project.

National defense and military industry

National defense and military industry

Special underground protective structures (such as underground command posts and military reserve depots) require structures with extremely high resistance to seepage, earthquake resistance, and blast resistance.

Partner Type

Regarding cooperation, we adhere to the following principles:

"Customer First" and "Win-Win Cooperation"(Putting customers at the heart of collaboration for shared success.)

Provide technical support and other services, including support on devices.
