Settlement correction work | Repairing cracks in the foundation and local settlement with steel pipe piles to restore value!

Fundamental solution for local subsidence and cracks in the foundation! A structural repair that utilizes the building's own weight to drive steel pipe piles into the supporting layer, protecting asset value.

Localized subsidence and cracking occurring in the foundation of residential buildings are significant structural issues caused by uneven ground subsidence and localized softening. If left unaddressed, the tilt of the building will further increase, leading to a substantial decrease in asset value and reduced seismic resistance. The subsidence correction work provided by Geotech utilizes the building's own weight as jack reaction force and employs a steel pipe pile pressing method, where high-strength steel pipe piles are driven deep into a hard support layer. Piles are precisely anchored at the locations of localized subsidence, and accurate leveling is restored through precise jacking. Additionally, epoxy resin injection is applied to the cracks in the foundation concrete to restore structural strength, and high-density filling of air bubble mortar is used to raise the ground bearing capacity in areas of subsidence and underground voids. Construction can be carried out while residents are living in the home, minimizing noise and vibration, and compressing the construction period and costs to a minimum. We will permanently protect the structural safety and asset value of your important home.

Settlement correction work | Restoring trust by fixing settlement and cracks in the base foundation with steel pipe piles!

Immediate repair of shallow residential foundation settlement and cracks! A technology that prevents re-settlement and restores corporate trust using a steel pipe pile driving method that utilizes the building's own weight.

Local subsidence and cracks in the foundation of detached houses that occur after handover are very serious issues for contractors and house manufacturers in terms of customer response and after-sales support. Delays in identifying the cause and inadequate construction responses can lead to secondary complaints and a loss of brand trust for the company. GeoTech's subsidence correction work involves a steel pipe pile pressing method, where small hydraulic jacks use the weight of the building as a reaction force to drive steel pipe piles into deep supporting layers, precisely lifting the problematic foundation and restoring it to a high level of accuracy. Epoxy resin injection is applied to damaged concrete cracks to fully restore structural strength, and lightweight bubble mortar (air milk) is filled into ground cracks and voids to enhance ground contact. The work can be carried out while the residents remain in the house, significantly reducing the burden on homeowners with a short construction period and low vibration. With a reliable construction plan linked to the re-issuance of after-sales guarantees, we quickly resolve issues with homeowners and provide a deep sense of security.

Double Lock Method - Settlement Correction Work

All tilts and subsidence of structures and buildings will be corrected.

There are two main methods for settlement correction. 1. The method of raising from the foundation installed on the building's base. 2. The method of raising from beneath the building's foundation. The first method only has the effect of correcting settlement. It is not recommended due to the need for anchor cutting and foundation chipping. The second method allows for not only settlement correction but also continuous settlement suppression measures through support piles or ground improvement up to the ground support layer. Our company offers the following methods for raising from beneath the foundation as part of settlement correction work: - Steel pipe pile driving method (underpinning) - Double lock method (liquid injection method) - Pressure plate method - House lifting and raising method The steel pipe pile driving method and double lock method are techniques that can prevent future re-settlement. Additionally, all methods can be carried out while maintaining the living condition without having to move out. The construction cost of the double lock method is about half that of the steel pipe pile driving method.

Settlement correction work | Partial correction of cracks in the base foundation and localized settlement using steel pipe pile driving!

Fundamental solution for local subsidence and cracks in the foundation! A partial repair technique that utilizes the building's own weight to drive steel pipe piles into deep support layers, preventing further subsidence.

Localized subsidence and cracking occurring in the fabric foundation of a residence are serious structural defects caused by localized weakening of the ground or uneven soil pressure due to neighboring embankments or excavations. If left unaddressed, the building's tilt will progress, leading to significant disruptions in daily life, such as wall cracks and malfunctioning window frames. In GeoTech's subsidence correction work, we employ a steel pipe pile driving method that uses hydraulic jacks to vertically press steel pipe piles into a hard support layer deep below the surface, utilizing the building's own weight as a reaction force. Piles are precisely placed at specific locations where localized subsidence has occurred, and the building is accurately jacked up to restore it to a level state. Additionally, cracks in the foundation are treated with epoxy resin injection or U-cut repairs, and ground fissures or voids beneath the floor are filled with high-density air milk, thoroughly reinforcing the overall stability of the structure and the strength of the foundation. The work can be carried out while residents remain in the building, with low vibration and low noise. This is the optimal method for resolving fabric foundation issues at low cost and in a short construction period, regardless of the building's age.

Settlement correction work | Partial correction of settlement and cracks in the fabric foundation during occupancy completed with SWS investigation.

During residence, we will clarify the sinking and cracks of the slab foundation through SWS investigation! We will ensure safe construction while protecting your life with partial jack adjustments, eliminating the need for temporary housing.

This plan is a resident-friendly subsidence correction solution that precisely and safely repairs partial subsidence of the foundation and structural cracks while protecting the daily lives of residents. By conducting a pre-implementation SWS (Screw Weight Insertion) test and high-precision measurements of the floor levels inside and outside, we visualize the localized causes of subsidence and the unevenness of the ground. Based on the diagnostic results, we ensure dust prevention measures and safe pathways to prevent dust from entering the living space, and we carry out partial jacking using small hydraulic jacks. By lifting and correcting in millimeter increments while monitoring the building's minute movements in real-time with a 3D laser level measuring device, we can restore it to a level position without placing undue stress on walls or columns. For foundation cracks, we apply epoxy resin injection and, if necessary, use steel pipe pile driving and pressure plate reinforcement to prevent re-subsidence. We promise to achieve a worry-free construction process that incurs no temporary housing costs or moving expenses, minimizing the mental and financial stress for the client.

Settlement correction work | Repairing settlement cracks in the fabric foundation using SWS investigation and partial jacking.

Investigating the causes of partial subsidence of the foundation and structural cracks through SWS surveys! We will reliably restore the client's trust with partial jacking up and re-attaching ground guarantees.

This plan is a solution for contractors and house manufacturers that covers everything from the scientific clarification of the causes of partial subsidence of the foundation and structural cracks that occur in homes after delivery, to precise corrections and warranty provisions. By conducting SWS (Screw Weight Insertion) tests and high-precision measurements of the building in advance, we visualize the factors of uneven subsidence in the ground and present a correction plan based on clear evidence. We adopt an approach of "repairing while living" that does not require temporary housing or moving, and we prevent secondary complaints through thorough site management with dust protection and low-noise construction. In the construction process, we use a small hydraulic jack in conjunction with a laser measurement device to accurately return the building to a level position without applying pressure to it, down to the millimeter. Along with repairing foundation cracks, we perform permanent ground reinforcement using steel pipe piles and pressure plates, providing a one-stop solution that includes reissuing ground warranties. We aim to transform the trust of clients who have been discouraged by troubles into a solid positive impression by providing "greater peace of mind than at the time of new construction."
