Outdoor Hotel Roof Top – Water Tank Lining
In fact overtime, GRP water tanks start to deteriorate. This is mainly due to the constant immersion of water. Consequently, the internal walls start to blister, and cavities start to form. It is these small cavities that start to retain stagnate water which will allow the bacteria to grow. For this reason, you can give your GRP water tank the ultimate protection it needs by relining. By using a solvent free polyurethane WRAS approved coating system designed to cure at low temperatures. This is an example of a Hotel cold water storage tanks that are in need of repair and lining.
The Problem: Water Tank In Need of Repair
The hotel have been experiencing issues with the water quality, which was attributed to the deteriorating condition of the two external water storage tanks. During a regular inspection of the cold water tanks, it was discovered that the internal walls had numerous blisters and were contaminated with microbiological growth spores. Some of these blisters had even begun to crack, leading to further problems with leakage in the GRP system.
The Solution: Water Tank Lining
To save costs, the water tanks on the hotel’s roof will be repaired by relining them instead of replacing them. This process will involve applying a protective coating to prevent leaks and minimise the growth of bacteria. The relining will be done in two stages. The first tank will be completed this week to ensure a continuous water supply for hotel guests and staff. While the second tank will be completed the following week to ensure a constant supply of cold water for the hotel’s water services.
The Team’s Step-by-Step Guide to Water Tank Lining:-
Step 1 – In order to ensure the integrity of the tank, it is necessary to drain the tank and thoroughly inspect the internal walls for any signs of blisters or cracks.
Step 2 – And so, this is the best stage of the process to waterproof and seal the tank.
Step 3 – The walls of the tank will undergo a mechanical process to prepare them internally.
Step 4 – In order to apply the solvent free polyurethane coating system, the tank will first undergo a thorough cleaning and vacuuming process. This preparation ensures that the tank is free from any contaminants or debris that could interfere with the effectiveness of the coating.
Step 5 – Apply a heavy stripe coat using brushes, followed by a full coat with rollers.
Step 6 – Once the initial coat is cured, you can apply the second coat using a different color for contrast.
Step 7 – When the tank lining is cured, it is important to conduct checks on the dry film thickness.
Step 8 – Finally, after the tank undergoes the lining process, it will be fully functional once again.
The Benefits of Water Tank Lining
Water tank lining offers several benefits. Firstly, it makes the tank easier to clean, ensuring that maintenance is more efficient and effective. Additionally, tank lining improves the overall water quality, ensuring that the water stored in the tank remains clean and safe for use. Furthermore, by reducing bacterial growth, tank lining provides essential protection for GRP water tanks, prolonging their lifespan and preventing potential damage or contamination.
Last, but not least once the water tank lining process is complete, our team goes the extra mile by providing cleaning and chlorination services for the tanks. We prioritise cleanliness and safety by collecting and analysing microbiological samples at a UKAS accredited laboratory. Furthermore, to give you peace of mind, we will provide you with a detailed completion report. Along with a tank certificate and microbiological test results, to show you that your stored water is both safe and compliant with regulations.
