One.Overview
Due to the high water content and extremely soft soil in cities like Jakarta and Surabaya, foundation stability is the lifeline of rectification projects. We employ a comprehensive approach of “active locking + static monitoring + minimally invasive control” to establish five core defense lines, ensuring the building remains in a “statically controlled” state throughout the entire rectification process.
Two, Five Core Defense Lines
(1) “Pile Foundation First”: Physically Blocking Instability Risks (Defense Line One)
Foundation instability often occurs because the building is still floating on “jelly-like” soft soil.
Strategy: We strictly adhere to “lock first, straighten later.” Before rectification, we use static pressed piles to anchor the building load directly to the deep bearing layer.
Effect: The building no longer relies on unstable shallow soft soil for support, fundamentally eliminating the possibility of sudden sinking or collapse during the rectification process.
(2) “Millimeter-level Stepping”: Maintaining Soil Mechanical Balance (Defense Line Two)
Soft soil exhibits high sensitivity, where severe disturbance can lead to soil liquefaction (Liquefaction).
Strategy: Strictly implement linear fine-tuning, controlling daily displacement within 1mm – 5mm.
Effect: This slow movement does not trigger shear failure in the soil, allowing ample buffer time for the redistribution of foundation stress and ensuring the soil maintains stable supporting force at all times.
(3) “Digital Sentinels”: 24/7 Monitoring and Early Warning (Defense Line Three)
Strategy: On-site deployment of total stations, high-precision digital tiltmeters, and crack gauges.
Real-time linkage: Monitoring data is synchronized with construction commands. Upon detecting abnormal fluctuations in settlement rates, the technical team immediately intervenes to make adjustments.
(4) “Stiffness Enhancement”: Strengthening the Building’s “Risk Resistance” Capability (Defense Line 4)
Many self-built houses lack a complete frame system (Ring Balk/Kolom Utama).
Strategy: Perform pre-reinforcement on structural weak points before construction, install steel supports to enhance the overall stiffness of the building.
Effect: Even if there are minor fluctuations in the underground soil layer, the house can shift as a solid whole, preventing structural cracks caused by uneven local stress.
(5) “Reverse Pressure Stabilization”: Instantaneous Risk Hedging (Defense Line 5)
Strategy: Grouting equipment is always kept on-site as a backup.
Effect: Once signs of soil loosening are detected, quick-setting materials are immediately injected into the foundation to artificially create an instant support point, achieving “reverse pressure stabilization” and swiftly leveling out foundation fluctuations.
Three, Specialized Protection for Specific Environments
Flood Prevention and Drainage Protection During Rainy Seasons: Heavy rains can cause sudden rises in groundwater levels, softening the foundation. We will install temporary drainage systems and waterproof curtains around the excavation site to prevent soil loss at the base due to rainwater erosion.
Neighborhood Joint Protection: In the high-density Gang/Narrow Alley environment, we not only monitor property owners’ homes but also simultaneously monitor neighbors’ foundations to prevent chain reactions caused by pressure transmission.
Four, Summary: Standardized Construction vs. Risky Operations
Even in complex geographical environments, foundation instability can be anticipated and prevented through scientific methods.
| Safety Dimension | Our Professional System (Robust Type) | Traditional Aggressive Correction (Adventurous Type) |
| Foundation Support | Piles Reach Hard Soil with Clear Force Transmission | Relying on topsoil, bearing force blindly and dangerously. |
| Power Control | Digitized linear push-up with uniform force distribution | Blind pressure application based on experience is prone to sudden instability |
| Monitoring Coverage | Full-time digital monitoring, data-driven decisions | Relying on manual observation of the level gauge results in extremely long lag times. |
| Emergency Response | Equipped with reverse voltage regulation technology, enabling second-level resolution | Lack of emergency supplies, evacuation is the only option when accidents occur |
Our integrated solution perfectly combines foundation reinforcement and straightening, eliminating the risk of “tilting” from the very first day of construction, with a safety factor for the straightening process far exceeding that of ordinary indoor additions.
