I. Overview
Absolutely. Due to rapid urbanization, repeated road elevation (Peninggian Jalan), and land subsidence issues in some cities (such as Jakarta and Semarang), houses becoming lower and experiencing backflow (Banjir Rob/Cileuncang) is very common. Overall elevation (Peninggian Bangunan/House Lifting) is currently recognized as the most thorough and permanent solution, with effects far surpassing building flood walls, digging drainage ditches, or installing water pumps.
II. Why is the overall elevation the “fundamental solution” for flood control in Indonesia?
Simply raising the yard or entrance cannot prevent underground water seepage or prolonged heavy rain.
Physical Elevation: The lifting technology physically raises the entire building along with its foundation, permanently elevating the indoor floor level (Peleton) above the surrounding road elevation and the highest water level during the rainy season.
Eradicating Risks: It fundamentally eliminates the possibility of water backflow from entrances, drainage outlets, or even floor cracks, protecting furniture, appliances, and interior finishes from flood damage.
3. Is your house suitable for lifting?
1-3 Story Common Brick-Concrete Houses (Rumah Bata Merah / Hebel): The most mainstream residential type. We first reinforce the walls through structural underpinning (Suntik Betul/Reinforcement), then use a hydraulic synchronous system to steadily lift the house, ensuring structural stability during the elevation process without causing cracks.
Modern Framed Concrete House (Struktur Beton Bertulang): Excellent structural integrity. The lifting process is not only safe but also faster than conventional brick houses due to the complete beam-column system.
Traditional Wooden & Stilt Houses (Rumah Panggung): A testament to traditional wisdom. If your old wooden house has lost its “stilted” height due to foundation sinking, we can easily lift it back up and even extend the foundation pillars to restore its ventilation and moisture-proof functions.
Shop Houses & Terraced Houses (Ruko): Both can achieve precise lifting, typically between 30cm to 1.5m, customized based on road elevation and drainage needs.
4. The “Premium” Additional Benefits of Whole House Lifting
Synchronous Correction: If your house has tilted (Miring) due to soft soil, the lifting process can simultaneously realign and restore it to its original position.
Space Value-Adding: After lifting, the newly created lower space can be repurposed with a reinforced foundation or even converted into a raised floor for storage or parking, effectively expanding the building area.
Structural Reinforcement: During the lifting process, the original foundation will be strengthened to enhance the overall safety of the house in seismic zones (Zonasi Gempa).
Property Value Preservation: Properties that have completely resolved flooding issues will see a significant increase in value and rental yield in the secondary market.
V. Legal and Industry Tips
Construction Window: Property owners are advised to contact us for surveys during the dry season (Musim Kemarau) to ensure elevation work is completed before the rainy season arrives.
Qualification Requirements: Ensure the selection of a professional team with local engineering qualifications (NIB/IUJK).
Extreme Limitations: Elevation is not recommended only when the main structure of the house has severely deteriorated due to long-term water exposure, with load-bearing walls turning powdery or crumbling, or if the building has been deemed at imminent risk of collapse.
VI. Summary
Faced with the continuous rise of road levels and frequent flooding during the rainy season, “raising houses along with the road” is the most scientific solution. As long as the house structure remains sound, a complete elevation is the best choice to protect family assets and bid farewell to the “flood-fighting lifestyle.”
Expert Tip:
Upon completion of the elevation process, we will redesign the separate drainage systems for domestic sewage and rainwater for you, ensuring your new elevated drainage system can smoothly connect to the municipal pipe network, completely solving waterlogging issues.
