Understanding Subsurface Barriers
Definition and Importance
Subsurface barriers are structures created below the ground surface to contain or isolate contaminants, stabilize soil, and manage groundwater flow. These barriers play a critical role in environmental protection and construction projects by preventing the spread of pollutants and improving site stability. For instance, in mining operations, subsurface barriers can prevent toxic substances from seeping into the water table, safeguarding nearby ecosystems and communities.
Types of Subsurface Barriers
There are several types of subsurface barriers, each designed to address specific challenges:
- Slurry walls: These are constructed by excavating a trench and filling it with a bentonite slurry to create a barrier that prevents the movement of groundwater.
- Jet grouting: This method involves injecting cementitious grout into the soil under high pressure to improve its strength and stability.
- Deep soil mixing: This technique mixes soil with cementitious materials to form a stable and impermeable barrier.
- Trenchless construction techniques: These methods minimize surface disruption while creating subsurface barriers, making them ideal for urban environments.

Construction Methods for Subsurface Barriers
Slurry Walls
Slurry walls are a popular method for creating subsurface barriers, particularly in environmental remediation and foundation support projects. The process involves excavating a trench and filling it with a bentonite slurry, which acts as a temporary support. Once the trench is filled, concrete panels are placed to form a permanent barrier. Our expertise in this area ensures that the slurry walls are constructed with precision and durability, providing a high level of groundwater containment and soil stabilization.
Jet Grouting
Jet grouting is a technique used to improve soil strength and stability by injecting cementitious grout into the soil under high pressure. This method is highly effective in creating subsurface barriers for ground improvement and tunneling projects. The high-pressure injection allows for precise control over the grouting process, minimizing disruption to the surrounding environment. Our Peristaltic Pumps and Slurry Pumps are specifically designed to handle the rigorous demands of jet grouting, ensuring consistent performance and reliability.
Deep Soil Mixing
Deep soil mixing is a versatile construction method that involves mechanically mixing soil with cementitious materials to form a stable and impermeable barrier. This technique is widely used in foundation support and groundwater containment projects. Our Colloidal Grout Mixers and Hurricane Series Mixers are optimized for deep soil mixing, offering high efficiency and accuracy. The resulting barriers are cost-effective and provide long-lasting protection against contaminants and groundwater issues.
Trenchless Construction Techniques
Trenchless construction techniques are becoming increasingly popular due to their ability to minimize surface disruption. These methods are particularly useful in urban areas where traditional excavation can be challenging and costly. Our Conveyors and Silos, Hoppers & Feed Systems are designed to facilitate trenchless construction, ensuring that the mixing and pumping of grout can be done efficiently and effectively. This approach not only saves time and money but also reduces the environmental impact of construction projects.
