I. Overview
Basically, no. In formal and professional shifting and lifting projects, we aim for “zero structural intervention.” Through advanced underpinning and synchronized hydraulic technology, the house maintains force balance throughout the moving process. In regions with variable climates like Indonesia, professional construction not only preserves the original appearance but also addresses historical issues caused by foundation settlement (ambles).
Will there be cracks? (Struktur & Retak)
Conclusion: No new structural cracks will occur.
Rigid Base Guarantee: Before shifting, we construct a closed reinforced concrete ring beam (Ring Balk) around the house’s base. This acts like a protective shield, preventing localized stress on the walls.
PLC Precision Control: Indonesia’s uneven geology makes manual lifting prone to cracking. We use a computer-synchronized system to keep deviations within 1.0mm, ensuring the entire building moves as smoothly as an elevator, with walls free from torsional shear forces.
Regarding “existing cracks”: If your home already has cracks due to previous settlement, these cracks may show slight reactions during the lifting process. This is actually a positive sign of structural realignment. After completion, we will perform professional structural epoxy injection and aesthetic repairs, making it stronger than before.
3. Will there be any leaks? (Kebocoran and Sanitation)
Conclusion: The construction process does not interfere with the waterproof layer and will optimize pipeline connections.
Waterproof Layer Protection: The lifting and shifting operations primarily occur at the building’s foundation level, without disturbing the waterproof layers of the roof (Atap), exterior wall finishes, or kitchen and bathroom areas.
Pipeline Expansion Handling: Considering Indonesia’s rainy climate and high groundwater levels, we will install temporary expansion joints on all incoming and outgoing water pipes (Pipa Air). After the lifting is completed, we will realign and reinforce the seals to ensure the new connections can accommodate future minor foundation adjustments, preventing any leaks.
Moisture Barrier Reinforcement: Post-lifting, as the house is elevated away from waterlogged ground, the original issues of dampness (Lembap) and mold on the lower walls will be fundamentally improved.
4. Will the doors and windows warp? (Frames & Windows)
Conclusion: Door and window frames maintain their original precision, with smooth operation as before.
No-squeeze construction: Door and window deformations are typically caused by building tilt leading to frame compression. After comprehensive underpinning, the door and window frames move smoothly along with the entire structure without bearing any compressive or torsional stress.
Environmental Adaptability Adjustment: Wooden doors and windows (such as Kayu Jati) are susceptible to humidity. After construction is completed, we conduct a comprehensive balance check on all doors and windows in the house. If the original doors and windows have developed slight misalignment due to long-term tilting of the structure, we perform fine-tuning after lifting and straightening to restore them to optimal operating condition.
5. Compliance Tips for the Indonesian Environment
Seismic Stability: According to Indonesian SNI 1726:2019, we will enhance the overall structural stiffness during underpinning, which means your house will have a lower risk of wall cracking during earthquakes compared to before construction.
Dry Season Recommendation: For optimal sealing and repair results, we recommend performing the final exterior patching work during the dry season (Musim Kemarau) to ensure the durability of the joint filler materials.
VI. Summary
Choosing a professional specialized engineering team means your property will receive “medical-grade” precision treatment. The post-construction property won’t just be free from cracks, leaks, or deformation—it will actually enhance living safety and comfort by addressing underlying settlement issues.
Expert tip:
If you plan to replace windows or exterior wall coatings while relocating the house, this is an excellent time for synchronized construction. In the elevated state, workers can more easily access hard-to-reach corners, thereby improving the overall quality of the renovation.
