Alternatives and Reasons for Choosing Concrete Canvas
Before learning about Concrete Canvas, shotcrete was an option for this project. Concrete Canvas was the solution because it was easier and faster to install than shotcrete.
Environmental Conditions
The project is being implemented in a crusher area that is still under construction, so many areas are impassable.
Land Preparation
- Vegetation Clearing
- Land Contour Releveling
Installation, Bonding, and Sealing Methods
The Concrete Canvas CCX-M is installed vertically with overlap joints. Fastening is done using 30 mm stainless steel screws spaced 10 cm apart at each overlap. Additionally, 25 cm J-Pins are installed at each joint on the slope to ensure the Concrete Canvas adheres perfectly to the soil substrate.
Hydration Method
The hydration process is carried out using a hose connected to a water truck.
Installation Duration
Installation productivity reaches around 200–300 m² of Concrete Canvas per day.
Project Success
The project was deemed a success. The client was satisfied with the ease of application and will evaluate this success for installations at other locations.
