Residential building on the road to Birmingham, which was first commissioned in the 17th century. Historically, the end of the road leads to a farm and further to a large pond. Over time, the road and the land around it turned into a modern street with houses
at both sides. The area where the pond once stood was reclaimed and an apartment building was built. The lack of proper attention to geology and the heavy construction of the building caused subsidence.
A house of six apartments sank into the ground on one side. This led to a violation of the integrity of the entire structure. Cracks could be seen along the entire perimeter of the building, so a long-term solution was required to stop subsidence. Uretek has developed a solution that reinforced the base soils with geopolymer resin to form a stable base with the required properties.
In order to achieve these goals, uretek used geopolymer resin in the subsidence zones to strengthen the soil and prevent further subsidence. Expansive geopolymer URETEK resins were injected at points along 101 meters of load-bearing wall structures. The injection tubes were placed in the drilled holes at a depth of 2-3 meters. After the resin is applied, it expands with tremendous force, forming the basis for its further use as a support for the foundation.
The work was completed within two weeks. Throughout the project, no residents were required to leave the property, which is a significant benefit of using the injection process. The foundation soils under the property have been reinforced and provided with a solid support.
