Waterproofing and Leak Repair Techniques
Leakage is a real headache, and a typical waterproofing and repair project generally involves four steps. Today, let's introduce them to you.
1. Inspect water leakage, 2. Analyze the cause of leakage, 3. Design a patching plan based on the cause, 4. Perform waterproofing construction.
There are numerous causes of leaks, and it's quite challenging to determine them. Experience in construction is crucial. Here are two examples of leaks. One type of leak is relatively simple—a seepage, where water drips down drop by drop, similar to the situation in the author's home. The reasons for this type of leak can vary greatly, such as the aging of the waterproofing layer in the upper floor bathroom, which may have developed holes, or perhaps the creation of leaks during a second renovation. The water from the bathroom seeps through the holes in the waterproofing layer into the gaps in the floorboard.
This issue is relatively easy to resolve; it's a simple water leakage, and there are two solutions. One is to apply a waterproofing slurry, which requires a slurry machine, typically costing over $2000. While it may not solve the problem completely, applying the slurry acts as a temporary patch for minor leaks, usually resolving common leakage issues (addressing the user's concern). The other solution is to break open the ground of the upper floor bathroom and redo the waterproofing layer, which can be done for about $5000. Regardless of the complexity of the project, the first thing to consider is the relationship between the neighbors on the upper and lower floors.
What materials are best for waterproofing and leak repair?
The Gubite I Type waterproofing mortar has been effectively utilized in waterproofing and leak repair. This material is a waterproofing agent produced from imported architectural specialty polymer latex as raw material, further refined with a variety of additives to form a waterproof latex, thereby enhancing the cement slurry's tensile strength and improving the waterproofing and leak repair performance.
2. Introducing another waterproofing and leakage repair material: the LB-1A solvent-free, environmentally friendly polyurethane waterproof coating rubber. This material is a new type of polymer chemical reaction product, which is mixed with many additives such as polyurethane prepolymer, hardener, and mold inhibitor, resulting in a highly effective overall waterproof rubber membrane.
3. The LB-2 solvent-free, environmentally-friendly colored polyurethane waterproofing rubber is a new type of synthetic high polymer reactive two-component waterproof rubber coating. It is composed of polyurethane prepolymer (Component A) and a mixture containing hardener, filler, plasticizer, fungicide, thixotrope, and pigment, among others (Component B). When mixed in a specific ratio and cured, these two components form a dense, elastic, and multi-colored overall waterproof rubber membrane.
LB-30 Waterproof Insulation Paint utilizes the anti-solar radiation mechanism of aerospace satellite insulation coatings, incorporates nanomaterial stable composite technology, and is an energy-saving and environmentally friendly single-component water-based coating developed independently on the basis of existing high polymer waterproof materials. It also features new functions such as decoration, insulation, heat preservation, waterproofing, and crack resistance, making it an eco-friendly building coating.
