π§ Solution for Weak Ground Treatment: Perspective from the Ministry of Construction & Technology Application Okasan Livic Vietnam
On May 7, 2025, the Ministry of Construction issued recommendations on a series of solutions to treat weak soil to ensure the stability of foundation structures and road surfaces in transport, civil and industrial infrastructure projects. In that context, Okasan Livic Vietnam - an enterprise with experience in transferring Japanese technology in foundation treatment - has been providing effective solutions suitable for geological conditions in Vietnam.
π‘ Recommended Solutions for Treating Weak Soil
According to the Ministry of Construction, the main methods currently include:
1/ Load-reducing floors / cement piles - Fast construction, high efficiency but high cost.
2/ Vertical drainage - Using wicks or sand wells, low cost but requiring a long waiting time for settlement (8-12 months).
3/ Vacuum suction - Shortens consolidation time to 3-4 months, high efficiency but requires strict technical requirements.
4/ Excavation to replace soil + bamboo piles/melaleuca piles - Suitable for thin weak soil layers, low cost, easy to construct.
ποΈ Technology Solutions From Okasan Livic Vietnam - Optimized for Vietnamese Conditions
Based on technology from Japan, Okasan Livic has been applying the following modern solutions:
1. β EPS Material (Expanded Polystyrene)
EPS is a lightweight material specialized in replacing soil in foundation construction, especially in areas with deep weak soil and requiring reduced load on the foundation.
Advantages:
Super light weight → reduces foundation pressure.
Fast construction, no need to wait for settlement.
High resistance to settlement and uneven settlement.
Environmentally friendly, sustainable over time.
Equivalent applications:
→ Replaces load-reducing floors or cement pillars, with equivalent efficiency but more optimal cost in the long term.
2. β Drainage Reinforcement Pipe System (PDR)
This is a solution to treat weak ground by consolidation method, using permeable pipes arranged vertically in the ground to drain water and increase stability.
Advantages:
Shorten consolidation time to about 3-6 months.
Minimize settlement after construction.
Flexible construction according to the site.
Equivalent applications:
→ Compatible with the wick method or sand well, helping to speed up construction progress while keeping costs at a reasonable level.
3. β Takino Filter Vegetation Mat
A complementary solution, used to prevent slope erosion and control surface runoff, ensuring long-term stability for infrastructure works.
Advantages:
Effective anti-slip, anti-erosion.
Easy to construct, environmentally friendly.
Increases green coverage and aesthetics of the work.
Supplementary applications:
→ Combined with embankment works, slopes, drainage ditches, roads...
π Conclusion: Cost Optimization - Time Reduction - Long-term Sustainability
In the context of Vietnam's traffic infrastructure requiring both effective and economical solutions, Okasan Livic Vietnam is proud to bring advanced technologies that can be flexibly applied according to the geological conditions of each area.
Our solutions not only comply with the professional direction of the Ministry of Construction, but also demonstrate a commitment to quality, progress and environmental protection.
