Water tank and reservoir waterproofing are essential to prevent water leaking that can harm the safety and purity of water. Other factors like fungus growth or water pressure can severely affect your potable water tanks if they are not waterproofed correctly.
Sika premium quality products ensure you succeed in your projects, as they comply with the strict regulations of public water authorities.
Some industries like food and beverage rely on high performance of Sika waterproofing systems in their process water tanks.
As global leaders, it's our duty to ensure hygiene, durability and resistance to exposure and stress conditions.
Need technical assistance on waterproofing?
Sika waterproofing products used in potable water reservoirs and tanks comply with the strict regulations of SPAN (Suruhanjaya Perkhidmatan Air Negara / National Water Services Commission). The food and beverage industry relies on the high performance of Sika waterproofing systems in their process water tanks.
The waterproofing of reservoirs and tanks containing potable water must be:
- Watertight over long periods
- Easily maintainable
- Food safe
- Harmless to health
Typical Exposures and Tips for Design
There are many factors that may affect the degradation of water tanks and structures in water treatment plants. By understanding the cause of damage, you can better know how to treat it, repair it and prevent it from long-term deterioration. These are the most common exposures affecting water storage areas.
General Considerations for Design and Specification
- Durability and water-tightness
- Exposures, site conditions and ecology
- Easily maintainable
- Food safe and harmless to health
- Compatibility of systems
- Life cycle costing
1. External Waterproofing
To keep drinking water in below-ground storage tanks clean, it has to be protected from groundwater entering the structure.

2. Concrete Solutions
The Sika Watertight Concrete System offers a comprehensive solution for watertight structures. The system consists of concrete that has been specially modified with Sika admixtures to produce waterproof concrete and carefully selected waterstops for construction and movement joints. Watertight concrete structures can be designed to keep water in or out, or both.
