1. Use waterproof coating with better performance
Due to exposure to nature, the waterproof layer of the balcony is exposed to hot sunlight, gusty winds, rain and snow, cold and hot temperatures, no good performance and good protection measures, and it is difficult to achieve the required durability. Therefore, waterproof materials with high tensile strength, high elongation and good aging resistance should be selected.
2. Balcony wall waterproof layer height thickness
In general, the waterproof coating of the balcony should not be lower than 30 cm, and the height of the washing machine is higher. If it is an exposed balcony, it is recommended to be higher in order to enhance the waterproof effect. In terms of thickness, the waterproof coating must be brushed to the national acceptance specification of 1.5 mm thick.
3. Balcony doors and windows ensure sealing
For the enclosed balcony, the first waterproof door is the door and window of the balcony when the wind and rain come. The quality and sealing of the doors and windows should be good, and the inside and outside of the waterproof frame should not be mistaken.
4. The balcony floor needs to have a slope
Unclosed balconies will flood into the water in case of heavy rain. In order to prevent rain from entering the room, the horizontal inclination should be considered when the floor is installed to ensure that the water can flow to the drainage hole and the water cannot flow to the room. The floor of the balcony should be 30-60 mm below the floor of the indoor floor, with a gentle slope to the drainage direction, and a water-blocking rim at the outer edge to introduce water into the rainwater pipe.
5. Install a smooth drain of the floor drain
In heavy rain and typhoon, when the rainfall is greater than the drainage capacity of the floor drain, it is possible to form stagnant water on the balcony floor. When the water volume is too large, it may flow over the waterproof frame of the sliding door to enter the room. Therefore, when choosing a floor drain, it is best to choose a drain that has a large displacement and a smooth drain.
