The "NLG Method" by Aso Foam Crete is a construction method aimed at filling back cavities in tunnels and voids between structures and the ground using non-air-based grout materials. It is particularly adept at long-distance pumping and is used for repair work in long tunnels. Additionally, it maintains a stable state (non-separation) even underwater, making it suitable for construction in areas with groundwater or underwater. 【Features】 ■ Capable of long-distance pumping up to 5,000m ■ Excellent filling properties ■ High non-leakage and non-shrinkage characteristics ■ Superior underwater non-separation resistance ■ Good workability and stability *For more details, please refer to the PDF materials or feel free to contact us.

"Light Fill Foam" is a premixed type of air mortar that only requires water to be mixed. Due to the lightweight and fluidity characteristics of air mortar, it is suitable for cavity filling, and high-quality air mortar manufacturing and filling work can be carried out using a dedicated plant. The compactly designed dedicated plant enables construction in small-scale projects and narrow areas, which were previously less applicable. [Features] ■ Just mix with water ■ Ideal for cavity filling due to lightweight and fluidity ■ Achieves high-quality filling by using a dedicated plant ■ Effective for small-scale projects and narrow areas *For more details, please refer to the PDF materials or feel free to contact us.

While leaving the bridge piers and girders intact, we will fill the voids beneath the bridge with aerated concrete to convert it into an earth structure. This will eliminate the need for regular inspections and repairs of the buried bridge, contributing to its longevity and also resulting in reduced running costs thereafter. Additionally, since the work will be carried out only in the space beneath the bridge, there is no need for external scaffolding for the assembly of formwork panels, allowing construction to proceed without completely closing the road to traffic. In an era where maintaining and managing existing infrastructure to extend its lifespan is essential, our air mortar technology will respond to the needs of the times.

The newly introduced Air Pack method is a revolutionary technique that has improved "water-sensitive air mortar" into "water-resistant air mortar." Air mortar and air milk had the weakness of separating air and solid particles when in contact with water, but the Air Pack method addresses this weakness. It allows for limited injection to maintain a plastic solid state instantly, and since there is no material separation, uniform strength can be achieved. This method is suitable for backfilling injections in conditions of spring water, stagnant water, and flowing water, as well as for filling cavities in areas that come into contact with water.

We hold technical seminars nationwide, focusing on the FCB method, with case studies on applications to roads and bridges. These can be utilized for in-house training sessions, study groups, and technical training sessions for association members organized by consulting associations. We welcome requests regarding duration, presentation content, etc. Web-based participation is also possible. Please feel free to contact us. 【Example Seminar Content (approximately 90 minutes)】 ■ FCB (Foamed Mixed Lightweight Fill) Method ■ Case Studies on Applications to Roads and Bridges ■ Case Studies on Applications to Ports, Rivers, etc. ■ Others *For more details, please refer to the PDF materials or feel free to contact us.

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.
