Whether water injection and grouting are reliable.

Waterproofing, plugging, grouting and grouting are commonly used waterproof treatment methods. Its principle is to fill holes and cracks by injecting special waterproof materials, so as to achieve waterproof effect. This method can solve some water leakage problems in small areas to a certain extent, but its reliability needs to be evaluated according to specific conditions. First of all, the quality of grouting materials and the technical level of grouting are the key factors affecting the waterproof effect. If the grouting material is of poor quality or the injection process is not in place, it may lead to uneven grouting, missing injection and other problems, thus affecting the waterproof effect. Secondly, grouting can only solve local problems. If there is a serious water leakage problem in the whole building structure, grouting alone may not achieve the expected effect. At this time, comprehensive waterproof treatment is needed, including measures such as improving building structure and strengthening waterproof layer. Therefore, grouting is a reliable waterproof treatment method, but its effect needs to be evaluated according to the specific situation. It is suggested that building structure, water leakage, grouting materials, construction technology and other factors should be comprehensively considered when selecting waterproof treatment methods, and the most suitable waterproof treatment method should be selected.
