[Column] The El Niño Method That Can Be Applied Even in Areas with Abundant Groundwater

Even in sites with abundant groundwater, the El Niño method can be applied.

**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.
