The roof is the top layer of the entire building, and the top layer is a structure made of cement or concrete. When cement roofs are eroded by rainwater for a long time, they are prone to leaks. After leaks occur on the roof, we usually have to waterproof the roof and repair leaks. But how to make waterproofing and leak repair more effective? Let the editor of Sichuan Xingguangda Let me give you the answer!
Once the roof leaks, there are usually two methods: indoor grouting and roof waterproofing renovation. Indoor grouting usually involves grouting here and leaking there. Repeated grouting not only damages the structure but also affects the mood. If the economy is not rich enough, grouting can be a way to solve the problem. Here are several ways to repair roof leaks.
1. Gap filling Most roof leaks are caused by cracks. Therefore, when repairing leaks, you first need to fill the gaps with leak sealing paste. After it dries, apply an additional layer of waterproof coating .
2, waterproof coating Waterproof coating is a material commonly used to repair roof leaks. First, apply water-based waterproof coating on the gap twice, at least 20cm.
3, Pouring concrete
If the roof leaks in a large area, a layer of concrete can be laid on the roof. At the same time, you can also lay concrete after finishing the SBS waterproof membrane. First use steel bars to make a mesh on the roof, and then solidify the top with concrete. However, it needs to be maintained for half a month after construction, such as watering or watering on it. Cover things to protect.
4. When constructing the waterproof layer, it is necessary to clean the base surface first, level the base surface, expose the concrete layer, clean the debris on the base surface, and fully moisten the base surface. Then check for cracks in the base surface and fill them levelly.
