Waterproofing and Leak Repair Methods & Techniques: Combining waterproofing with a long-lasting, flexible and rigid integrated waterproofing and leak sealing process.
1. Drill joints according to the specified quantity as required by Party A.
2. Clear the leaky areas, chisel the leaky cracks into U-shaped slots.
3. Mill leak seam, pre-bury bamboo joints, clean the leak seam, fill and seal with material, install drainage pipes and bamboo joints (grout nozzle).
4. Redirect water flow, reduce pressure, decrease water volume, control leak points, convert large water flow to small water flow, and allow the small water flow to exit through the installed redirection tubes.
5. Ingredients: Mix several reagents into two batches of liquid slurry. Determine the solidification time of the ingredients based on the amount of leakage.
6. Reverse Pressure Grouting: The pressure of the grout must be greater than the leakage pressure to push the water back and infiltrate into the capillary cracks of the leaking rock. Upon contact with water, it expands and sets quickly, achieving long-term deep-seated water stoppage.
7. Excavate bamboo joints (optional), then fill in with packing material directly.
8. Surface treatment: After self-inspection with no leakage, level the surface with the paste.

Waterproofing and Leak Repair Selection Standards:
1. Adhesion to the base material
2. Permeability
3. Compression and tear strength
4. Weather resistance, aging resistance.
5. Surface Adhesion of Decorative Materials
General Waterproofing and Leak Repair Practices: During the process of residential renovation, areas that generally require waterproofing include bathrooms, kitchens, balconies, etc.

How to tackle the "difficult problem" of selecting waterproofing and leak repair materials for basements?
Although we have established waterproofing specifications for basements, requiring waterproof designs for underground projects, basement issues have always been a major headache. A waterproofing and leak repair specialist discusses the current waterproofing measures used for basements from two aspects.
Yes: Self-sealing concrete
Self-waterproof concrete, also known as self-waterproof reinforced concrete structures, is a crucial defense against water leakage in engineering. It boasts low cost, simple processes, ease of construction, and a wide range of material sources, making it a preferred choice. Design should ensure that the structural thickness is not less than 250mm; thicker wall thicknesses can be selected appropriately under certain conditions, and high-strength concrete should be avoided to enhance the structure's impermeability and reduce hydration heat during construction. The key to quality control for self-waterproof concrete structures lies in careful selection of construction materials and a series of crack prevention measures.
1) Compensating shrinkage self-sealing concrete structure
2) Waterproofing for basement construction should combine rigid and flexible waterproofing measures. The thickness and strength grade of the self-waterproofing concrete structure should be selected according to the structural design, with its impermeability grade not less than P8. It is advisable to add micro-expansion agents, densifiers, water-reducing agents, etc., to the concrete.
Pay attention to the following two points for water resistance:
1. Fills and seals tunnels, dams, basements, bricks, and concrete components, bonding all contact surfaces against both dry and wet cracks.
2. Grouting of cracks in water-pressure ground water flow can be配合 with low dosage catalysts, forming foam within 2 seconds upon contact with water and fully expanding and solidifying within 10 minutes.
2. Rolled Waterproofing:
Synthetic polymer waterproof membrane, polymer-modified asphalt waterproof membrane, or synthetic polymer waterproof coating (suitable only for external waterproofing and external bonding methods).
The waterproof membrane is directly bonded to the main structure's outer surface, in sync with the concrete structure, minimizing the impact of structural settlement and deformation. It's less prone to damage during construction, making it convenient to inspect the concrete structure and the quality of the membrane. Issues can be easily repaired. The drawback is that it requires multiple construction stages, has a complex process, and a longer duration. It demands a large working area, significant soil volume, and a high quantity of formwork, with the membrane joints being difficult to protect, which can affect the quality of the waterproofing work.

Waterproofing and leak repair is an indispensable part of home renovation. By using concrete and waterproof coatings, buildings gain防水performance, thereby ensuring homes are protected from the侵蚀of heavy rains and accumulated water. Nowadays, there are countless options on the Chinese market, each showcasing its strength in various aspects.
The construction quality is reflected in the long-term development of our operations, where we strictly enforce the construction methods of each worker. Additionally, in our daily operations, we provide guidance and training to every worker, ensuring they possess excellent construction skills and service demeanor.
2. To achieve a higher waterproofing effect, rigorous construction procedures are implemented, including leak source detection with equipment and gap filling with coatings. The construction process strictly adheres to the steps and standards for raw materials, ensuring superior construction quality and enhanced durability.
3. It's reflected in enhancing construction capabilities while also improving after-sales service. When防会 offers reliable after-sales support, we conduct systematic inspections and trials post-acquisition to ensure effective control of leakage sources and to eliminate the possibility of recurrence. Therefore, Chinese consumers need to choose institutions with such capabilities to carry out waterproofing and leakage repair work, so that their home's life and property safety can be fundamentally protected and they can enjoy a more worry-free living experience.
