A, the basement exterior wall, roof, post-cast strip leakage treatment process
1, surface treatment method: surface treatment method: firstly, brush the concrete surface with a steel wire brush to remove the dirt attached to the surface, rinse it with water, after drying, fill the surface defects of concrete with epoxy mastic and latex cement, and finally brush it with selected materials.
2. Grouting method: Grouting method is to use all kinds of resin grout, cement grout or polymer cement grout to pour into the deep part of cracks under a certain pressure, so as to achieve the purpose of restoring structural integrity, durability and waterproofing.
3. Filling method: When there is water, use quick-setting admixture or quick-setting patented cement (inorganic or organic) instead of portland cement. For dry and thin open joints, organic polymer-based caulking and putty materials can be used, and lead fibers are often used together with traditional caulking materials.
4. Grouting method: suitable for local treatment of expansion joints near the water surface; Grouting is generally carried out from low to high. When the grouting is discharged from the front hole, the grouting is completed in the back hole.
Second, the roof leakage treatment
Treatment of roof leakage: drilling and grouting are strictly prohibited. The principle of treatment is to completely solve the leakage. It is suggested to find the leakage point, dismantle the roof and find the reason from the waterproof layer.
Third, the external wall leakage treatment
1. The main types of external wall seepage are: external wall seepage caused by filler wall, external painting construction quality problems, improper repair of reserved holes, joint seepage of external wall windows, etc.
2. Judgment of the severity of the leakage problem
3. Common treatment methods of external wall leakage
Step 4 glue
Four, toilet leakage treatment measures
1, accurately find the leaking part.
2. When there is obvious water accumulation on the ground after the urinal is used, the water leakage at the joint between the urinal and the drain pipe should be considered first. At this point, the ground at the water inlet of the urinal can be gently removed to check whether the rubber bowl is in good condition. If damaged, it must be replaced immediately.
3. Flooding effect of the floor drain with accumulated water is not good. When there is frequent water accumulation, the ground around the floor drain should be chiseled and the slope should be found again to make the floor drain.
4, wear floor riser should be embedded casing, and 20mm higher than the floor, casing external use GK rapid setting plugging agent tightly, the gap between casing and riser with elastic cement waterproof coating.
5. The waterproof layer of toilet and toilet is the key to waterproof and leak-proof.
Waterproofing plays a very important role in the workshop. If there is leakage problem in the factory building, we must find a professional construction team to stop leakage in some important places in the factory building, such as basement, roof, external wall and bathroom. The whole process, including waterproof materials, waterproof process construction links and construction effects, should be strictly controlled and supervised to avoid unnecessary troubles caused by waterproof material quality problems or construction process problems. Bian Xiao has introduced in detail the specific methods to solve the waterproof and plugging of the factory building, so you may wish to refer to it.
