Arai Corporation - Mortar Injection Work for Stone Walls

Cheaper and shorter construction time than demolition and transfer! Ideal for reinforcing conceptual stone masonry and for weed removal effects.

The stone wall mortar injection work involves injecting mortar (a mixture of cement, sand, and water) into the gaps between stones using mechanical pressure, which acts to "reinforce" the stone wall, "eradicate weeds," "improve drainage management," and "enhance aesthetics," thereby reducing the concerns and burdens of owners managing stone masonry. The stone wall mortar injection by Arai Co., Ltd., boasting over 30 years of experience and achievements, has been certified as a new technology (NETIS) by the Ministry of Land, Infrastructure, Transport and Tourism. 【Features】 - More cost-effective than demolition and reconstruction - Possible to shorten construction time - Ideal for reinforcing existing stone masonry and weed removal - Mortar is injected through the gaps between stones using mechanical pressure - Improved drainage management and enhanced aesthetics For more details, please contact us or download the catalog.

Water Stopping Works: High Pressure and Low Pressure Injection

In low-pressure injection, injection is performed using specialized equipment.

In underground structures, we will inject chemical solutions into areas prone to water leakage, such as construction joints, cold joints, cracks, honeycombs, separators, and concrete penetrations around H-beams. For water stop treatment of leaks from joints and cracks in existing concrete, we will insert a plug into the leak point and use a specialized pump to inject the chemical solution at high pressure. *For more details, please feel free to contact us.

Underground Injection Construction "Set Form Method"

Filling gaps with rigid polyurethane foam! It excels in stability, water-stopping effect, and workability.

The "Set Form Method" is a technique used in the repair work of existing tunnels, where voids behind the lining concrete are filled with rigid polyurethane foam. Rigid polyurethane foam hardens in about one minute after injection and reaches its final strength in 30 minutes, providing excellent early stability. Additionally, if using rigid polyurethane foam that expands 40 times, the amount of materials transported and the injection volume are only one-fortieth of the actual void volume. 【Features】 - Minimal penetration and escape into the surrounding ground, reducing the injection volume - Construction possible within a budget based on actual void volume - The weight on the lining concrete is lightweight at 30 kg/m3 - Excellent water-stopping effect as it expands and hardens even underwater - Can be constructed without time constraints, among others *For more details, please feel free to contact us.

Void injection construction

Injecting cement-based filler into the gaps under the foundation! Restoring a safe and comfortable living environment.

"Void Injection Work" is a method used when a void (cavity) is confirmed beneath a building. Cement-based filling material is injected into the void under the foundation. By stabilizing the building on solid ground, it is possible to reduce earthquake damage. This method can prevent the tilting of the building and restore a comfortable and safe living environment. 【Features】 - Suitable when a void (cavity) is confirmed beneath the building - Cement-based filling material is injected into the void under the foundation - Reduces earthquake damage by stabilizing the building on solid ground - Prevents the tilting of the building and restores a comfortable and safe living environment *For more details, please refer to the PDF document or feel free to contact us.
