Settlement correction work | Repairing settlement and cracks in the cloth foundation without stopping the utility lines!

Construction without stopping city gas or water supply! A technique for safely leveling the settlement and cracks of strip foundations using a steel pipe pile driving method that relies on the weight of the building.

Localized subsidence and cracking in residential shallow foundations can not only cause tilting of the building but also place excessive strain on the plumbing and equipment under the floor, potentially leading to damage incidents. Typical subsidence repairs often involve temporary suspension of utilities and moving to temporary housing, which can impose a significant burden on homeowners. GeoTech's subsidence repair work offers a groundbreaking jack-up plan that can be executed without interrupting essential services such as city gas, water supply, and electricity. While installing flexible joints to prevent pipe breakage and taking careful protective measures, we press and install steel pipe piles into deep hard layers using the weight of the building as a counterforce. We precisely lift the subsided shallow foundation to restore it to a level position within millimeters. At the same time, we inject epoxy resin into the cracks in the foundation concrete to restore strength and waterproofing, and we fill the voids in the subsided ground under the floor with high-density air-entrained mortar (air milk). This allows for construction while living normally, minimizing both the construction period and costs.
