1.<\/b><\/strong>Overview<\/b><\/strong><\/span><\/span><\/p>\n

Due to the widespread presence of deep soft soil and frequent groundwater extraction along the northern coast of Java (Jakarta, Karawang, etc.), the settlement remediation of existing buildings cannot rely solely on “patching cracks where they appear.” It requires a systematic approach of “first stabilizing the foundation, then fine-tuning for correction, and finally repairing the structure.”<\/span><\/span><\/p>\n

II. Core Remedial Measures<\/span><\/span><\/b><\/strong><\/p>\n

\u2474<\/b><\/strong>\u3001<\/b><\/strong>Settlement Stabilization: Completely cutting off the sinking path<\/b><\/strong><\/span><\/span><\/p>\n

This is the most critical step in soft soil areas, aiming to transfer the load from the shallow soft soil to the deeper bearing stratum.<\/span><\/span><\/p>\n

Anchor Static Pressure Pile (Anchor Top Pile)<\/span><\/span><\/b><\/strong><\/p>\n

Method: Utilize the building’s own weight as a reaction force to press steel pipe piles or precast concrete piles into the ground using hydraulic equipment.<\/span><\/span><\/p>\n

Adaptability: Extremely suitable for Indonesia’s dense Ruko (shop houses) or fully equipped factories. With no vibration during construction (no disturbance to residents), no noise (not affecting Friday prayers or community peace), and the ability to operate indoors, it is the preferred choice for reinforcing old urban areas in Jakarta and Surabaya.<\/span><\/span><\/p>\n

Micro Pile \/ Root Pile (Micro Pile)<\/span><\/span><\/b><\/strong><\/p>\n

Method: Use small drilling equipment to create holes in the foundation, implant steel bars, and inject high-pressure cement grout.<\/span><\/span><\/p>\n

Suitability for Indonesia: Ideal for mountainous and sloping areas like Bandung. Its compact equipment can access narrow alleys (Gang) in Indonesia, and its strong anti-sliding capability effectively resists soil erosion during the rainy season.<\/span><\/span><\/p>\n

Chemical Grouting Reinforcement (Chemical Grouting)<\/span><\/span><\/b><\/strong><\/p>\n

Method: Inject high-pressure polymer or cement-based materials.<\/span><\/span><\/p>\n

Suitability: Specifically addresses “piping” and underground voids caused by Indonesia’s rainy season. Quickly seals underground water channels, making it particularly suitable for emergency reinforcement of warehouse floors without halting operations.<\/span><\/span><\/p>\n

\u2475<\/b><\/strong>\u3001<\/b><\/strong>Rectification and Leveling: Restores buildings to a level position.<\/b><\/strong><\/span><\/span><\/p>\n

If the building has developed significant tilt (Tilt), rectification should be carried out after settlement has been stopped.<\/span><\/span><\/p>\n

Lifting Correction (Jacking Up)<\/span><\/span><\/b><\/strong><\/p>\n

Method: Set up a jack on the side with significant settlement and slowly lift it synchronously; or arrange grouting pipes on the side with larger settlement and perform grouting to lift.<\/span><\/span><\/p>\n

Advantages: The process is gentle. For Indonesia’s numerous historic buildings (such as the old Batavia historical structures) or mosques, the jacking method allows precise millimeter-level control, protecting fragile masonry from secondary cracking.<\/span><\/span><\/p>\n

Controlled Settlement Correction<\/span><\/span><\/p>\n

Method: Controlled soil excavation on the less settled side, utilizing gravity to induce realignment.<\/span><\/span><\/p>\n

Advantage: Relatively low cost, suitable for industrial areas with uniform geological conditions.<\/span><\/span><\/p>\n
