Measures before it's too late: Countermeasures against sinkholes due to aging underground cavities and sewer pipes.
Reinforcement that ensures safety against underground cavities and aging sewer pipes! We provide construction methods adapted to various site needs.
We would like to introduce various construction methods for the measures against "sinkholes caused by the deterioration of underground cavities and sewer pipes" proposed by our company. Starting with the "Bubble Concrete Method," which uses civil engineering materials that incorporate air bubbles into slurry-like mortar, we also offer the "NLG Method" using non-air grout materials, and the "Air Pack Method," which is suitable for backfilling injection in conditions of spring water, standing water, and flowing water. Additionally, we handle the premixed type air mortar "Light Fill Foam," which can be used simply by mixing with water. 【Examples of Measures】 ■ Bubble Concrete Method - Allows for flexible design of strength and density, enabling long-distance pumping with a pump. - High workability, making it easy to construct on steep slopes and other challenging terrains. - Low permeability and excellent long-term durability. ■ NLG Method - Excellent filling capability, allowing for long-distance pumping up to 5,000 meters. - High non-leakage and non-shrinkage properties. ■ Air Pack Method - Water-resistant air mortar with high applicability in water environments. - Capable of uniform strength and stable injection. ■ Premixed Air Mortar - Can be used simply by mixing with water. - Effective for small-scale projects and confined spaces. *For more details, please download the PDF or feel free to contact us.
basic information
【Pipeline Filling Work / Void Filling Work】 To prevent ground subsidence and deformation of buried pipes, air mortar is used for filling within pipelines to secure and protect the pipes. It is widely adopted in many pipeline installation projects due to its excellent long-distance pumping capabilities. ■ NLG Method (Capable of 5,000m Long-Distance Pumping) This method uses non-air grout materials for filling voids behind tunnels and cavities between structures and the ground. It is particularly effective for long-distance pumping and is suitable for repair work in long tunnels. Additionally, it maintains a stable state (non-separation) even underwater, allowing for construction in areas with groundwater or underwater. ■ Air Pack Method (Water-Resistant Air Mortar) This method is suitable for injecting backfill in conditions of groundwater, standing water, or flowing water, as well as for filling voids in areas that come into contact with water. It maintains a plastic solidification state instantly, allowing for controlled injection without material separation, resulting in uniform strength. ■ Light Fill Foam (Premixed Air Mortar) Due to the lightweight and fluid characteristics of air mortar, it is well-suited for filling voids. With just a bucket and a hand mixer, anyone can easily produce and fill high-quality air mortar, making it effective for small-scale construction projects.
