The villa lighting well was made into a big fish tank. What should I do to never leak water?

The villa lighting well was made into a big fish tank. Waterproofing can be done in the following ways, so as to be permanently watertight and impermeable. It is our best way to put a fish tank in the light well of the villa, because the light well is useless and can be placed and used well, and the fish tank will be beautiful, but there will be water seepage problems. Waterproofing is very important, because there is a basement under the villa, and water leakage will affect the following situation. Without basement waterproofing, some harmful phenomena can be avoided. The bottom and edge of the pool should be paved with 20 cm of concrete, with steel bars as its core. Fill up the pit after watering and use the best waterproof material to make it waterproof. Only in this way can the waterproof pool easily seep around, and it can be waterproof after five times. Because all our villas have bought waterproof pools, we don't care about the money, so we must ensure that there is no water leakage. But for this kind of outdoor engineering, it is better to find professional people, because they have enough experience to install it, which can not only save money, but also their professional materials and workmanship can achieve good results, ensuring that our lighting well can achieve the effect of seepage prevention, and after waterproofing is done, its guiding device should also be done well. In rainy days, if the pool is full of water, it must be dredged to prevent the water from flowing out of the pool. The advantage of the lighting well is that it solves the lighting problem in the house, because if it is a villa in the deep, its light will be affected and will not shine in the room, so it is necessary to strengthen its lighting and ventilation, so the lighting and ventilation effect is good and can be used well. But when we make a fish tank, we should also do it according to our actual situation. If there is not enough money, we can do it ourselves. If the funds are abundant, we can let professional experts do it, because they can make it watertight forever.
