Client/Project Owner: Coal Mining Company in East Kalimantan
Amount of Concrete Canvas Used: 885 m²
Roll Format: Bulk Roll
Type/Thickness: CCX-M
Layup Method: Transversal
Installation Process
Equipment used
- Excavator
- Cutting/Multipurpose Blade
- 25 cm J-Pin
- 30 mm Stainless Steel Screw
Alternatives and Reasons for Choosing Concrete Canvas
Crushed stone was considered as an alternative, but this method requires a relatively long installation time. Rainy season conditions were also a major consideration, as they could potentially slow down work and reduce installation effectiveness. Therefore, Concrete Canvas was chosen for its quick installation process and the enhanced waterproofing protection provided by its integrated LLDPE layer.
Environmental Conditions
The ground in the work area is quite soft due to rain so it needs to be smoothed.
Land Preparation
- Channel profile formation
- Land contour re-leveling
Installation, Bonding, and Sealing Methods
Concrete Canvas CCX-M was installed transversely with overlap joints. Fastening was performed using 30 mm stainless steel screws spaced 10 cm apart at each overlap. Additionally, 25 cm J-Pins were installed at each joint in the anchor trench.
Hydration Method
The hydration process is carried out using a hose connected to a water pump, with the water source coming from a nearby pond around the project site.
Installation Duration
Installation productivity reaches around 400–500 m² of Concrete Canvas per day.
Project Success
The project was deemed successful, due to the rapid installation.
