Royal Decree 140/2003 establishes the sanitary criteria for the quality of water for human consumption. In relation to the membranes used in tanks and pipes, this decree requires that they must be certifi ed for contact with water intended for human consumption. Therefore, the use of membranes certifi ed in accordance with RD140/2003 is a guarantee that safe materials suitable for contact with drinking water are being used in the repair of leaks and tanks.
At Tecnopol we have two certifi ed solutions for the repair of water tanks and pipes. The first is DESMOPOL DW, a manually applied two-component polyurethane membrane, which is characterised by its ease of application and excellent mechanical properties.
The second option is TECNOCOAT P-2049, a waterproof polyurea membrane that is applied hot by spraying equipment. This membrane dries quickly and has impressive mechanical properties, making it ideal for repairs in highly demanding areas.
Both options are certified for contact with water intended for human consumption and guarantee the safety and quality of the water supplied. The application technique of the liquid membrane is relatively simple and consists of preparing the surface to be repaired, applying the primer and applying the liquid membrane in several layers until the desired thickness is reached.
The liquid membrane adheres perfectly to the surface, covering any cracks or crevices and forming a durable waterproof layer.
The advantage of the liquid membrane is that it is very flexible, which makes it ideal for use in tanks that are subject to deformation due to changes in temperature or water pressure. In addition, the liquid membrane is highly resistant to chemicals and corrosion, making it suitable for use in water tanks containing corrosive substances.
In conclusion, tank repair with liquid membranes is an effective and durable solution for water leaks in tanks. Liquid membranes are easy to apply, resistant and safe for contact with water intended for human consumption, making them an ideal choice for water tank repair.
