In ground improvement work on site, we will explain the differences between other methods and the "El Nido Method" from two perspectives this time. ▼Difference 1: Soil Disposal and Environmental Consideration▼ For example, in columnar improvement, it is common for the excavated soil to be discarded. As a result, the leftover soil is often treated as industrial waste, leading to increased disposal costs and greater environmental impact. On the other hand, the El Nido Method reuses the soil generated on site during excavation. The amount of leftover soil is about 35% for cohesive soil, and nearly zero for sandy ground. ▼Difference 2: Quality Control that Allows for "Direct Achievement" of Target Strength▼ In many ground improvement methods, there tends to be a significant difference between pre-mixing tests and actual on-site strength, necessitating a large safety factor due to variability in strength. For example, in conventional methods, the ratio of [on-site test specimen strength / pre-mixing test strength] is typically around 0.2 to 0.8. (Note: The "=" here indicates a range, so please recognize it as "nearly equal.") However, with the El Nido Method, we achieve [test specimen strength / mixing test strength ≧ 1.0]. In other words, the strength obtained on site is equal to or greater than that from the pre-laboratory tests.

**Challenges of Sites with High Groundwater** In construction and civil engineering sites, there are many concerns related to "groundwater," such as: - Groundwater springs up immediately upon excavation. - The groundwater level is high, preventing excavation to the required depth. - There is a risk of construction interruption or quality issues due to rainwater and other factors. - Particularly in cases where the groundwater level is high, it is not uncommon for traditional methods to be deemed "impossible to construct." **Reasons for Choosing the Elneed Method** ◎ Flexibility to handle groundwater The Elneed method incorporates an "adjusted water content ratio" in its mix design and manages the water volume within the fill using "flow values," allowing for the utilization of "sprung water and sudden rain." **Reasons for Feasibility of Construction in High Water Level Sites** - Adoption of excavation and mixing methods that suppress groundwater inflow. - Setting a higher elevation for the initial finish, then shaving down to the required height the next day to avoid the effects of water level. - Establishing a reliable construction system through quality assurance and N-value determination during the design phase. **Conclusion** Do not give up on a site just because the water level is high. With the Elneed method, construction is possible even under conditions of groundwater volume, groundwater level, and during the rainy season.
