Mitigation of liquefaction risk in existing buildings

Mitigation of liquefaction risk in existing buildings

Liquefaction is the phenomenon where the soil behaves like a liquid during an earthquake, losing its strength and stiffness. With our developed method, we apply a specialized resin injection to the ground, which helps mitigate the risk of liquefaction. This ensures the safety of existing structures by enhancing the ground's stability and reducing the potential for soil liquefaction.

Vibration and Sound Isolation.

Vibration and Sound Isolation.

The method developed by Soilplus is an effective approach used to mitigate the effects of vibration and noise caused by metro systems in buildings. This method involves the injection of resin into the foundations and structural elements of buildings, effectively absorbing and reducing vibrations. Buildings can be affected by vibrations and noise generated by passing metros, but resin injection minimizes these adverse effects. As a result, both the durability of buildings is preserved, and the quality of life for occupants is enhanced.

Ports and water structures

Ports and water structures

The method developed by Soilplus is effective in repairing damages caused by seawater and other external factors, as well as enhancing the durability of structures. Resin injection strengthens marine structures by filling cracks, voids, or deformations and providing waterproofing. This improves the resilience of ports against erosion caused by waves and seawater. As a result, port and marine structures are made more durable, ensuring their long-term service life and uninterrupted operations.

Rehabilitation of historical structures

Rehabilitation of historical structures

Resin injection is an ideal solution for addressing foundation and ground issues in historical buildings, improving compacted or loose soils, and enhancing the resilience of structures. This method provides a solid foundation to the structure without compromising the original details of the historical building.

Rail systems

Rail systems

Resin injection is an ideal solution for addressing ground issues in railway lines, improving compacted or loose soils, and enhancing the resilience of rail systems. It also plays an effective role in stabilizing ballast embankments. When resin is injected into the ballast fill, it increases the stability of the ground, ensuring that the embankment remains solid and durable.

Industrial facilities

The Soilplus method is an ideal solution for addressing ground issues in industrial structures, filling cracks and voids, enhancing structural stability, and providing waterproofing. Resin injection effectively repairs damages in concrete structures, on the ground, or walls within industrial facilities.

Airports

Airports

The method developed by Soilplus is an effective approach used in the maintenance and repair of airport runways and taxiways. This method fills cracks and voids, corrects deformations, and enhances the durability of concrete surfaces. Preserving a smooth surface on airport runways and taxiways is crucial for ensuring safe take-offs and landings of aircraft. Polyurethane resin injection enables rapid and effective repair of cracks, ensuring uninterrupted operations. This method is an important solution for the sustainability and safety of airport infrastructure.

Soil-structure interaction model

Soil-structure interaction model

In our work, we focus on modeling soil-structure interaction, which involves analyzing the dynamic behavior and response of structures in relation to the surrounding soil. By understanding how the soil and structure interact, we can better assess the performance and stability of the structure under various loads and environmental conditions. As part of this process, we utilize advanced computational techniques and modeling tools to simulate the complex interactions between the soil and the structure. This allows us to accurately predict the behavior and response of the ground, enabling us to design and implement effective solutions. One such solution is the implementation of polyurethane resin injection, where we strategically inject resin into the soil to enhance its stability, fill voids, and mitigate potential issues such as settlement or soil liquefaction. Through this combined approach of modeling soil-structure interaction and implementing polyurethane resin, we aim to optimize the geotechnical performance, ensuring their safety and durability in various geotechnical conditions.

Mitigation of liquefaction risk in existing buildings

Liquefaction occurs when the soil turns into a liquid state due to factors such as earthquakes, posing a threat to the safety of structures.

Preventing water flow

This barrier fills the voids in the soil and prevents the passage of water. The high viscosity of the polyurethane resin enables it to effectively seal micro-cracks and voids.

Mitigation of ground-borne vibration and noise.

To mitigate ground-borne vibration and noise, resin is injected into the ground, reducing the transmission of vibrations and sound.

To determine if your building is located on liquefiable soil, it is important to consult a local engineering consultant. The potential for liquefaction can vary depending on the geological characteristics of your region, the bearing capacity of the soil, and other factors. An expert engineer can conduct the necessary investigations to assess the liquefaction risk of your building and provide guidance on appropriate measures to be taken. It is essential to have an engineering assessment conducted to ensure the safety of your building and minimize the risk of liquefaction.

The cracks in a building can be attributed to various factors, including structural issues or external influences. Here are some potential causes of cracks:

1. Ground movements: Earthquakes or ground movements are common factors that can lead to cracks in buildings. Earthquakes can induce stress on foundations and structural elements, resulting in crack formation.

2. Settlement and displacement: Ground settlement or displacement can cause cracks in buildings. Soil settling or shifting can impact the structural balance and stability of buildings.

3. Structural movements: Structural movements within the building can contribute to crack formation. Expansion, contraction, or changes in height of the structure can lead to crack development.

4. Material inadequacies or improper usage: Insufficiencies in building materials or improper usage can result in crack formation. For example, incorrect concrete mix, poor quality reinforcement materials, or faulty application can be the cause of cracks.

5. Moisture and water damage: Accumulated moisture or water within the structure can contribute to crack formation in building elements. Water leaks, high humidity levels, or improper waterproofing can lead to crack formation.

6. Exceeding load-bearing capacity: Overloading the structure beyond its load-bearing capacity can lead to cracks. Excessive loads, particularly on structural supports or foundation systems, can result in noticeable cracks.

7. Natural deformations: Buildings are subjected to natural deformations over time. These deformations can arise from factors such as normal usage, gravity, or climate changes. Over time, these deformations can lead to crack formation.

It is important to properly assess and identify the source of cracks. A structural engineer or expert can conduct a comprehensive examination to determine the causes of cracks and implement necessary measures. This allows for preventing further damage caused by cracks and ensuring the safety of the building.
