Landslides and slope erosion pose serious challenges in infrastructure development and construction projects. Therefore, advanced technology is required to strengthen and maintain slope stability.

In August 2013 in Barrio El Codito in Colombia, there were problems with the slopes so that slope protection and stabilization were required.

The slope had previously experienced surface erosion caused by weathering and vibrations from vehicles due to its proximity to the road. Therefore, a solution that could be installed quickly to prevent road closures due to construction was required.

The combination of concrete canvas and soil nailing is an innovative solution for slope reinforcement. Concrete canvas acts as erosion control, and soil nailing plays a role in slope reinforcement, providing dual protection for the slope. As illustrated below.

This process begins by placing Concrete Canvas on the surface of the slope to be reinforced. Then, steel soil nail rods are embedded vertically into the slope at the appropriate distance and depth to reach a stable soil zone.

These steel rods have heads at the top that serve to connect the slope wall structure that will be built above them. After the soil nail steel rods are embedded, the Concrete Canvas is wetted with water to trigger a chemical reaction and harden the material.

This will cause Concrete Canvas to become a strong and durable material, forming a layer that covers the slope surface and prevents erosion.

The use of Concrete Canvas combined with soil nailing has several advantages:

1. Work Speed : The quick and easy installation process of Concrete Canvas, as well as the efficient application of soil nailing, allows slope reinforcement work to be completed more quickly.
2. Durability : Concrete Canvas has high resistance to erosion, corrosion, and other environmental damage, thus providing long-term protection for slopes.
3. Shape Adjustment : Concrete Canvas’ flexibility allows adaptation to different slope shapes, including steep or complexly contoured slopes.
4. Better Environment : The use of Concrete Canvas and soil nailing reduces the need for conventional construction materials such as reinforced concrete, which can have a positive impact on the environment.

Conclusion : Concrete Canvas used as slope reinforcement combined with soil nailing is an innovative technology that offers an effective and efficient solution in dealing with slope stability problems.

This combination provides long-term protection and can help prevent erosion and dangerous soil movement.

With the advantages of speed of work, cost effectiveness, and high durability, this technology has great potential for use in various construction projects in the future.

However, as with any construction method, good implementation, proper design selection, and careful supervision remain key to ensuring the success and safety of this slope reinforcement project.
