Rapid Setting Waterproof Plugging Compound is a high-performance inorganic rigid waterproof repair material formulated with high-grade special cement, rapid-setting additives, and active waterproofing agents. It is supplied as a gray dry powder that quickly reacts with water to form a high-strength, impermeable solid structure.
Unlike conventional repair materials, this product can be applied directly under wet conditions and even with active water leakage. After mixing with water, it rapidly sets and hardens to effectively seal leaking cracks, holes, and joints, creating a strong bond with concrete substrates without shrinkage or cracking.
The material is specially designed for emergency waterproof repairs and leakage control in underground structures, water tanks, tunnels, basements, and concrete structures. Its inorganic, non-toxic formulation provides safe application for both civil and industrial waterproofing projects.
Key Features & Benefits
When waterproofing systems face urgent leakage problems, QINGYUAN Fast Setting Waterproof Repair Compound provides a rapid and reliable solution for emergency water stopping, crack repair, and concrete structure protection.
Rapid setting performance allows quick sealing of active leaks, flowing water, and emergency waterproofing points.
Water-reactive hardening technology enables direct application on wet surfaces and areas with active water leakage.
High early strength provides fast reinforcement and prevents further leakage after repair.
Non-shrink formula maintains stable volume after curing and prevents cracking or separation.
Strong bonding performance creates an integrated connection with concrete and cement-based substrates.
Excellent water resistance allows long-term immersion without powdering, erosion, or loss of strength.
Suitable for both positive and negative waterproofing repair applications in wet and underground environments.
Eco-friendly inorganic material contains no harmful substances and is safe for water-related structures.
Easy mixing and application allows quick repair with only clean water, reducing construction time and labor costs.

Standard Construction Process
Professional repair methods ensure rapid water stopping, strong bonding, and long-lasting protection for leakage repair applications.
Leakage Area Preparation
Open leaking cracks or holes into a V-shaped groove. Remove loose concrete, dust, and debris, then clean the area while keeping the substrate moist.
Material Mixing Preparation
Mix the powder with clean water according to leakage conditions. For urgent water stopping, prepare a dry and firm material ball for fast plugging.
Rapid Plugging Application
Immediately place the mixed material into the leakage point. Press firmly by hand or tools until the material fully hardens and stops water flow.
Surface Reinforcement Treatment
After the main leakage point is sealed, apply additional repair material around the area to strengthen waterproof protection.
Curing & Strength Development
Allow the repaired area to cure naturally. Maintain moisture curing when required to improve strength and waterproof performance.
Final Waterproof System Application
After the repair area is fully stabilized, apply waterproof coatings or install waterproof membranes to create a complete waterproof system.
