[Column] Thorough Comparison of 3 Methods / Column Improvement, RAPL, Elneed
Even with the same ground and the same building, differences in construction methods can change the size of the foundation. Variations in bearing capacity dramatically affect costs and construction time.
When considering ground improvement and foundation methods, the choice between "columnar improvement," "RAPPL method," and "El Nido method" significantly affects the size, cost, and duration of the foundation. ■ Differences in Long-Term Allowable Bearing Capacity of the Three Methods - Columnar Improvement: Approximately 300 kN/m² maximum - RAPPL Method: Minimum strength of 13,000 kN/m² - El Nido Method: Approximately 1,000 kN/m² maximum ⬛︎ Reasons for Choosing El Nido Using general-purpose equipment such as backhoes means that a smaller foundation directly translates to cost benefits. - Reduction in excavation volume → Decrease in disposal costs for surplus soil - Savings on material costs such as concrete and rebar - Shortened work time for excavation, reinforcement, and pouring The greatest strength of the El Nido method is that "design innovations are directly returned as cost benefits." The column also includes actual case studies for reference. Please take a moment to read it.

The Elneed Association handles the "Super Rappuru Basic Construction Method (Elneed Method)." This method uses stabilized soil created by mixing construction-generated soil with water and cement-based solidifying agents, and it is an improved version of the Rappuru concrete method for construction foundations. Our member companies are located from Tohoku to Kyushu, allowing us to respond to requests from all over the country. Please feel free to contact us when you need our services.
