1.Overview
In Indonesia, the life cycle of buildings typically faces more severe challenges than in other regions. The design objective of our reinforcement solution is to ensure the service life of the reinforcement system matches that of the main building structure (over 50 years).
II. Core Conclusion: Long-term Guarantee for Over 50 Years
Through targeted reinforcement, buildings will transition from relying on “unstable surface soft soil” to depending on “deep stable bearing layers,” achieving fundamental long-term stability.
III. The Three Pillars Supporting Long-term Effectiveness
⑴、Geological-level “structural risk avoidance”
Principle: For cities like Jakarta and Surabaya with silt layers tens of meters thick, our underpinning technology transfers loads to deep hard soil layers (such as hard clay or weathered rock).
Adaptability: This process completely avoids the “secondary consolidation creep” characteristic of soft soils (where soft soils gradually settle over time even without new loads). By embedding the foundation deep into layers minimally affected by groundwater level fluctuations, settlement is physically eliminated.
⑵、Material level ‘weather resistance adaptation’
Structural-level “Seismic and Dynamic Load Redundancy”
Anti-corrosion treatment: The piles we select can resist erosion from coastal salt spray (Salt Spray).
Weather-resistant grout: The special modified polymer or cement-based grout injected into the foundation maintains stable performance under ground temperatures that can reach 25°C – 35°C year-round, without softening or decomposing.
Resistance to storm scour: The formed reinforcement curtain has excellent anti-seepage properties, capable of withstanding the冲刷 of high-velocity groundwater during Indonesia’s monsoon season (Musim Hujan).
⑶、Structural-level “seismic and dynamic load redundancy”
Seismic redundancy: Our reinforcement system is designed in accordance with the SNI 1726 seismic fortification standards, ensuring the connection between the pile foundation and the existing foundation has sufficient shear strength to maintain stability and prevent settlement after light to moderate earthquakes.
Dynamic load resilience: For heavy-duty industrial plants, the reinforcement system can withstand repeated impacts from forklifts and heavy machinery over long periods, maintaining floor flatness without degradation over time.
IV. Risk Warnings Affecting Lifespan (Requiring Owner’s Attention)
Although the reinforcement system itself is highly resilient, the following external factors may shorten its apparent lifespan and require attention during later maintenance:
Extreme regional subsidence: In areas like North Jakarta where the average annual subsidence exceeds 10cm, although the reinforced building itself does not sink, the subsidence of surrounding ground may cause cracks or steps at the junctions between the building and roads.
Adjacent Illegal Construction: Excavation activities in neighboring plots without proper support measures may cause lateral disturbances to the reinforcement system.
Long-Term Overload Operation: The actual usage load consistently and severely exceeds the design’s ultimate load capacity (e.g., unauthorized conversion of a light-load warehouse into a heavy steel storage area).
Five, Summary and Commitment
Under normal maintenance and standard usage conditions, our reinforcement solution ensures:
No new settlement cracks due to foundation issues within 50 years.
After multiple rainy season cycles, the foundation’s bearing capacity shows no significant degradation.
Meets the long-term requirements of the SLF (Sertifikat Laik Fungsi) Certificate of Functional Suitability.
Core Logic: We’re not just selling construction services, but “long-term secure assets” for Indonesian land.
