Concrete water tanks are a popular choice for storing water in large quantities for drinking, irrigation, and firefighting purposes. Metal and concrete are the main components of tank construction. However, these materials are susceptible to corrosion and cracks. To protect the structure from damage and deterioration, waterproofing is mandatory.
Concrete is a porous material; it has tiny openings and capillaries that allow water to penetrate. The ingress weakens the structural integrity of the tank. Moreover, constant wetting and drying cycles can cause the tank to crack and erode. These crevices develop over time, causing more problems for homeowners and businesses.
Water seepage can contaminate the stored liquid. Soil, bacteria, and chemicals can become a part of the tank, causing deterioration in the quality and use of water. This contamination can render the stored water unfit for consumption, posing health risks to users. To prevent these problems, it is essential to apply the waterproofing process. In case of concrete water tanks, waterproofing is crucial for structural integrity and better aesthetics.
There are several methods of waterproofing concrete water tanks, each with its advantages and considerations:
Surface Concrete Tanks Waterproofing
This method involves the application of waterproof coating or membrane to the exterior surface of the concrete tank. Common materials for surface waterproofing include epoxies, acrylics, and elastomeric coatings. Surface waterproofing is easy to apply and maintain; it is effective in preventing moisture penetration. However, it requires periodic maintenance and recoating.
During integral waterproofing, admixtures are mixed to the concrete during the tank’s construction. These admixtures modify the concrete’s properties to reduce water permeability. Moreover, the concrete slurry is mixed to achieve the desired performance.
Crystalline waterproofing is a process in which chemicals react with water and unhydrated cement particles to form insoluble crystals within the concrete capillaries. These crystals block the passages of water, making the concrete impermeable. Crystalline waterproofing can be applied as a coating or added as an admixture. It is recognized for its effectiveness and self-healing properties (crystals continue to form over time).
For added protection, a geomembrane liner is the best option for the tank’s interior. Geomembranes are synthetic materials that provide an impermeable barrier between the concrete and the stored water. They are effective in preventing water leakage and contamination. However, proper installation is crucial to avoid punctures or damage to the liner.
The choice of waterproofing method depends on various factors, including the tank’s size, location, and intended use. It’s important to consult with a qualified engineer or contractor to determine the most suitable waterproofing solution for your specific needs. In addition to waterproofing, regular maintenance of concrete water tanks is essential for their long-term performance.
What is the Difference Between Waterproofing and Tanking?
Tanking is a process that involves the application of a waterproof membrane on the walls and floors of a structure. On the other hand, waterproofing includes the use of sealants, liquid chemicals, and other materials to protect the surface.
Ending: Concrete Tanks Waterproofing
Concrete water tanks require waterproofing to maintain their structural integrity and the quality of the stored water. The choice of waterproofing method is based on the specific requirements of the tank. With proper waterproofing and maintenance, concrete water tanks serve as a reliable and long-lasting solution for water storage, contributing to water security and sustainability.
