The house I bought on the third floor has an outdoor balcony, but every time it rains, there will be water. What should I do?

First, check the position of the window frame slot drain hole. If there is nothing wrong with the drain hole of the tank, seal the original hole and drill it again. Or let the property help solve the problem of stagnant water first, and then find the reason from the inside. You can also choose to add a ceiling above the open-air balcony or something.

In this case, you need to find someone who specializes in repairing balcony waterproofing. Use white iron plate to make the water edge, and then make waterproof layer along the top (cold asphalt waterproof coating can be used). The only way to avoid leakage is to make a glass cover wide enough. The glass awning can be made according to the white steel structure customized by the manufacturer.

Outdoor balconies often encounter wind and rain. In terms of design and material selection, I think it is best to be moisture-proof and waterproof, and the floor must be painted with waterproof paint. Use special waterproof coating and choose Yuhong brand waterproof coating. After a 24-hour waterproof test, plants can be planted on it. One. Clean up the grassroots. Cement mortar leveling, floor drain down slope 2/100; After brushing a layer of JS waterproof coating, immediately spread a layer of non-woven fabric, and then spread a layer of JS waterproof coating (note: the wall should also be turned 300 mm); After the waterproof layer is completely dried, conduct a 24-hour water retention test. Floor tiles shall be laid directly after drainage (it is best to leave a seam with a width of 5mm, and then treat it with structural adhesive).

How to seal the open-air balcony

Before the balcony on the roof is closed, it is necessary to negotiate with the property company before construction. Sometimes violations are found, including coordination between neighbors. In general, please ask the construction team to carry out the construction, using different materials and fire-resistant color steel plates. Plastic steel materials, on the premise of choosing light materials, reduce the load, but also need to be careful not to damage the waterproof layer. For small areas that only need to be covered, color steel plates can be used and all sides can be welded with angle steel. The interface is sealed with glass glue, which is convenient to use. Don't underestimate this building, be sure to invite professional engineering to do it.
