What are the solutions to water seepage on windowsills?

The reasons for water leakage on the window sill: the rainwater cannot be drained from the window frame, especially for sliding windows. All the rainwater accumulates in the groove of the sliding frame. When it is full, it seeps into the house; the installation workers have weak waterproof awareness. Or use non-specific sealing strips, resulting in loose joints and water seepage; improper handling of details, such as leakage caused by loose fixing screws; when installing windows, the proportion of concrete is unscientific, and construction only focuses on aesthetics, honeycomb The phenomenon of lumps is common. The windows and window sills are not connected properly, causing leakage. The original construction was careless and no waterproofing treatment was done, which caused leakage. Leakage material selection and waterproofing and leakage repair treatment methods: We must follow the principles of combining drainage, prevention and plugging, adapting measures to local conditions, and comprehensive management. Generally, leakage control requires professional and experienced construction site investigation to find out the cause of leakage, find out the leakage point, and then make specific Leak plugging implementation.

As for the gap leakage caused by the loose joints of the window frames, if there was colloid in the past, all of them need to be eradicated and cleaned, the cracks should be checked, and high-quality special sealing materials should be used to seal the gaps tightly. If the fixing screws are not sealed with sealing material, they also need to be sealed again; if the brick-concrete structure around the window frame is cracked or loose, it must be completely removed to the structurally stable base layer, and UD006 impermeable repair mortar should be used to fill the facade and upper frame tightly. For quick repair, you can use anti-seepage repair mortar mixed with leak-stopping king. The joints can be tightly caulked with sealing materials. For water leakage from cracks around the windows, find the specific location of the crack, use V-shaped groove processing, and use repair mortar to mix the leaks. Quickly repair, then apply polymer waterproof material, and then restore the decorative layer; for high-altitude operations.
