As we all know, swimming pools, underground water tanks are generally one of the essential items in daily life. If used for a long time, there will be a possibility of water leakage, water loss or reverse osmosis from underground water streams. With exposure to huge amounts of water 24/24 hours, water absorption is inevitable.

With many years of experience in the field of waterproofing, Hung Thinh waterproof please share your readers the best pool waterproofing reviews and solutions as follows:
Swimming pool waterproofing has 2 common cases:
- Apply sika pool waterproofing from the start of new construction.
- Waterproofing and troubleshooting when using.
In two cases we will have different approaches, but both require certain issues to be considered.

1. Determining exactly the cause of water leakage:
There are two core causes of leaks:
- Water from drainage tank (underground tank, terrace tank).
- The water from the groundwater seeps into the underground (underground tank).
For the first case, we apply the waterproofing method that is processed inside the pool or pool.
1.2 In the second case, the remedy is to waterproof the opposite direction of water inflow.

2. The materials of construction waterproofing the pool thoroughly:
- Grout self-leveling grout without shrinkage, to fill pipe neck, before expansion, it is necessary to swell swell rubber. The neck is very easy to absorb the position should be careful to do this part carefully.
- Special waterproof sealant that can withstand high pressure to crack treatment if any.
- Thorough waterproofing membrane, The selection as well as the application of the norm of waterproofing membrane used for swimming pools should pay attention to the height of the water level to give an idea of what materials to use.
- Two-component polymer cement elastic membrane, Sika topseal 109, Master Seal 540 (Basf) ...
- Specialized waterproofing admixture: Sika latex th.

Construction process:
- For a new construction swimming pool:
+ Remove the water book in the tank (if any), sanding the surface of the tank with a grinding machine
+ Technical treatment of cracks with specialized waterproof glue.
+ Blowing away dirt, chisel to erase convex and concave positions. Clean the surface, remove excess mortar, impurities by using high pressure hose.
After the surface of the surface has been dry, level and free of impurities
+ First we waterproof the floor drain: Use a chisel to chisel the neck from the mouth of the pipe from 2-3 cm in a V-shape and clean. Fill the neck of the tube to pour grout into another area, then wrap it around the neck with an expanded rubber bar, also known as an expansion gasket. Mix Grout non-shrink grout and pour into pre-filled floor drain tube.
+ Apply Sika latexTH waterproofing additive to increase adhesion to the surface of the tank.
+ Cover two layers of cement-based waterproofing membrane (Sika topseal 109; Master Seal ...) on the entire surface of the tank, between layers using reinforced mesh to prevent water from getting out the best.

For waterproofing of underground water tanks:
As for the cause of water in the tank, we follow the waterproofing solution mentioned above.
If the cause is due to groundwater, we offer the following remedy:
- Clean the entire surface of the tank.
- Wet the surface of the tank, next we apply Sika Latex waterproofing additive. Apply the two-component waterproofing mixture (Mater Seal) after the additive dries, it must be scanned at least 2 times, each time an average of 3-4 hours and depending on the weather. can be 4-5 (h) and hot weather can be 2-3 hours.
- If we do not do the above way, we can use the way of sticking the membrane with gas lamp, to fuse them to adhere to the surface of the tank with overlapping amplitude each time adjacent to 100mm.
- Finally, we reinforced with a layer of concrete to prevent water pressure of groundwater. And should combine with the waterproofing process of the pool to ensure long-term stability.
