Ponds containing acidic water often become a serious problem for the surrounding infrastructure. Damage caused by acidic water can deteriorate traditional pond lining materials in a relatively short period of time. However, our project in Sei Tohor, Riau, has proven that Concrete Canvas, an innovative material, can be an effective solution to overcome this issue, even without requiring a complex dewatering process.
What Is Concrete Canvas?
Concrete Canvas is a unique material made of two geosynthetic layers filled with dry cement and supported by a geomembrane layer underneath. This material has been proven to withstand fluids with pH levels ranging from pH1 to pH13, making it an ideal choice for lining pond edges containing highly acidic or alkaline water.
Case Study: Sei Tohor, Riau
The Pond Lining project in Sei Tohor, Riau, is a real case that demonstrates the successful use of Concrete Canvas under challenging conditions. The pond in Sei Tohor contains acidic water, with surrounding soil conditions that were already saturated. To address this issue, Concrete Canvas was selected as a solution to line the pond edges without requiring a dewatering process.
Advantages of Concrete Canvas in the Sei Tohor, Riau Case
Acid Resistant: One of the greatest advantages of Concrete Canvas is its ability to withstand acidic water environments. Concrete Canvas can even be hydrated using the acidic water available in the pond to activate the dry cement inside it without reducing the quality of the Concrete Canvas material itself.
Installation Without Dewatering: The dewatering process, which involves removing water from the pond, is often complicated and time-consuming. However, Concrete Canvas allows the lining to be installed without carrying out this dewatering process. This saves time, costs, and labor while allowing the pond to remain operational. The pond edge in Sei Tohor, with a water depth of 1.5 meters, was installed without dewatering and was able to harden perfectly. This Concrete Canvas installation has remained in good condition for up to six years after installation.
Adaptability: Concrete Canvas can be installed according to the desired pond design and dimensions, providing flexibility for project customization. Saturated soil along the pond edge, which previously could not be stepped on, can be shaped using formwork and lined with Concrete Canvas to create a uniform and neat pond profile.
Concrete Canvas Application in Sei Tohor, Riau
The application process of Concrete Canvas in Sei Tohor, Riau, involved the following steps:
Pond Preparation: Forming the pond edge profile using wooden formwork.
Concrete Canvas Installation: Concrete Canvas was installed along the pond edge according to the desired design.
Securing: Ensuring that the Concrete Canvas was properly and neatly installed along the pond edge. The upper section that was not exposed to water was secured using 30 mm screws spaced at 100 mm intervals. Meanwhile, for the section of Concrete Canvas submerged in water, it was secured using pegs at the bottom to hold the Concrete Canvas in position before it hardened.
Hydration: Concrete Canvas was hydrated using water from the pond. Although the water was acidic, Concrete Canvas could still be hydrated and hardened optimally.
Conclusion
The Pond Lining Project Case Study in Sei Tohor, Riau, is a real example of how Concrete Canvas can be an innovative solution for lining ponds containing acidic water without the need for expensive and complicated dewatering. The advantages of Concrete Canvas in terms of acid resistance, fast installation, and adaptability make it a wise option for projects facing similar challenges. With Concrete Canvas, ponds containing acidic water can be effectively protected, saving time and costs in the long term while also supporting environmental sustainability.hanan terhadap air asam, pemasangan yang cepat, dan kemampuan penyesuaian menjadikannya pilihan yang bijak bagi proyek-proyek yang menghadapi tantangan serupa. Dengan Concrete Canvas, kolam dengan air asam dapat dilindungi dengan efektif, menghemat waktu dan biaya dalam jangka panjang, serta menjaga keberlanjutan lingkungan.
