The first reason of balcony seepage: the waterproof work was not done well during the decoration, which led to seepage. The first step of waterproofing is to make the balcony floor waterproof, to ensure that the ground has a slope, and the low side is the drain. At the same time, it is necessary to ensure that there is at least a height difference of 2-3 cm between the balcony and the living room, and try to choose marble on the ground, which is both practical and beautiful. But both ends and bottom of the slate should be sealed to prevent leakage.
The second reason of balcony seepage: pipeline damage leads to seepage: Some owners put a lot of flowers and plants on the balcony, so installing faucets on the balcony can facilitate daily watering, but it is best to reserve various jacks and bury the pipeline before installing faucets. Circuit installation is a concealed project, so special attention should be paid to it during construction. If the circuit is tampered with and the correct construction steps are not followed, it is easy to bury potential safety hazards for the later period.
Second, how to deal with the balcony seepage?
1, waterproof layer thickness should be at least 5 mm during construction, and waterproof coating should be brushed for 2-3 times. Waterproof paint is also needed at the joint between the floor and the wall of the balcony and 30 cm upward. In addition, it should be noted that in the decoration and layout of family balconies, not only waterproof materials should be painted well, but also waterproof slopes should be remembered to facilitate water flow to the drain.
2. In order to level the balcony leakage and find the slope, first of all, cement mortar should be used to level the balcony floor and facade, and there must be serious waterproof problems.
3. If the balcony or skirting board leaks due to structural cracks, high-pressure grouting should be adopted. First find out the leaking parts, nail the leaking cracks, and inject waterproof foamed polyurethane at high pressure. After the polyurethane is cured, take out the nail. If the crack is too large, chisel off 200 concrete around the crack, fill the crack with fine stone concrete, and construct a 2mm thick polyurethane waterproof layer on the concrete surface.
Third, methods to prevent balcony seepage
1, the balcony is closed. Now more than 90% of newly-installed owners will choose to close the balcony, and the selected materials are crucial. Good aluminum alloy materials and good installation and decoration generally do not cause water leakage. Car owners should choose brand aluminum alloy materials with guaranteed quality and better after-sales service. The thickness of relatively solid aluminum alloy building materials is about 1.2 mm, and the actual thickness of many building materials declared as 1mm in the market may be only 0.8mm-0.9mm, which can be measured or carefully distinguished by the owner. In addition, a good aluminum alloy window is seamless, and it is not easy to have quality problems such as water leakage and window detachment.
It is necessary to choose a regular company.
Good decoration is also very important. Owners try to choose regular home improvement companies when conditions permit. Take waterproofing as an example. In the practice of decoration in Chen Chuang, the waterproof test will be done after the waterproof layer is done on the balcony floor. Fill the balcony floor with water and keep it submerged for 24 hours, even as long as 1 week. After confirming that there is no water seepage, start laying tiles and so on.
Formal decoration companies will also give a warranty. The warranty period for water seepage and leakage in balconies and bathrooms is generally 5 years. If you were looking for a regular decoration company before, all the expenses will be borne by the decoration company.
