Typhoon is coming. Is your home waterproofed properly?
Waterproofing has always been the top priority at all stages of decoration. If waterproofing is not done well, water leakage will easily occur in the walls and floors, and then mold will occur, which will not only damage the walls and floors, but also affect the neighbors, which will inevitably affect daily life! You must know that water seepage, water leakage, moisture return and other phenomena have their own reasons. , before the arrival of the typhoon season, take precautions first!
The key to treating illness is diagnosis
There are also intermittent showers in summer, coupled with the typhoons that love to join in the fun, It’s a test for many homeowners’ houses. It ranges from a puddle of water stains on the top of the wall to serious cases where the upstairs and downstairs have turned into water curtain holes. The reasons are also quite complex. When there is water in the house, you must first investigate the cause before you can solve the problem!
The enclosure structure is not tight enough
Usually, this is the first thing to consider The reason is that if there are gaps on the top of the wall that can seep water, the water will come down directly. This kind of water seepage is due to poor quality of civil construction. If there are built structures in the house, it may be that each waterproof node has not been properly handled.
Determine the water seepage of the building envelope
This type of water seepage needs to be wrapped with waterproof materials on the outer surface where water enters. For this construction, you can also find a professional waterproofing service provider. Because all internal sealing and grouting methods are not as reliable as surface treatment, that is, wrapping on the water surface.
Seasonal backflow of tide
This phenomenon is often seen in old villas. During typhoons every year, once the water overflows the roads in the community, it will pour into the basement and garage. If it overflows the external outlet of the floor drain, it will flow back indoors along the floor drain, which makes the owners very depressed.
There are almost no measures to prevent backflow: usually, the only effective way is to block the drain. Since this type of problem is related to municipal administration and cannot be involved in interior decoration, backflow is obviously disastrous.
There was no water seepage, just dampness: the basement floor tiles were as damp as if they had been soaked in water, and there was a musty smell in the air. If there are no other obvious symptoms of water intrusion, this is a normal phenomenon of moisture, that is, when moist air encounters a low-temperature environment or object, the water changes from gaseous to liquid.
There are also solutions to control moisture return: generally speaking, it is either ventilation or buying a dehumidifier. Turn on the dehumidifier. If there is a sewer pipe in the basement, plug the outlet pipe of the dehumidifier into it and it will work for a long time.
Pipes are passages: For decoration, all pipes are passages, especially those that communicate indoor and outdoor solar energy, security, garden lighting, air conditioning outdoor units and many other equipment. There will be a wire tube passing through the wall. body. When it rains and is windy, rainwater may be blown into the pipes and extend all the way in.
Treatment of pipe seepage
It took a long time to accurately locate and solve this kind of problem. You can check that all pipes extending out of the room must be bent downward at the end and extended by 3 to 5 centimeters so that there is no risk of water being blown in by the wind.
Correct pipe laying method: keep the parallel distance at least 10cm, the crossing distance at 5cm or more, and the minimum distance between hot and cold water pipes is 3cm. The distance between gas pipelines and water and electricity pipes should be at least 15cm to ensure that there are leaks and other problems in the pipelines. Since it is exposed to the external environment, it must be waterproofed to prevent rain, snow, etc. from penetrating indoors or downstairs.
Waterproofing should start from the source: the use of non-woven fabrics and scrapers is common in waterproofing projects. Apply the waterproofing treatment to the base layer once, wait for 2 to 4 hours to dry, and then repeat The waterproofing treatment is not complete until you apply it once. The paint should be applied evenly without any leakage, bulging or falling off, otherwise it will affect the waterproofing effect.
Construction acceptance and final inspection: inspection must be carried out carefully and carefully. Waterproof inspection requires a 24-hour closed water test. Light walls, corner joints and other places need to be sprayed with water to test for water seepage. The phenomenon of many water pipes bursting one after another is directly related to the narrow spacing between pipes. The hot and cold water pipes and the gas pipes are closely together, without leaving an appropriate distance according to the construction regulations, which obviously creates potential safety hazards.
Other factors leading to water seepage
In addition to the above-mentioned phenomena, there are also many factors that have nothing to do with the exterior wall, such as water seepage at the interface of sewer pipes, water intrusion into the dry pavement, and internal thread screws. Problems caused by leaving it too short.
