About CYH 500 SINGLE COMPONENT HYDROPHOBIC PU

91 000 74051 CYH-500 is a single-component hydrophobic polyurethane grout that, upon contact with water, expands into a closed-cell rubber-like foam. It is used to stop water leaks, fill small cracks, joints, honeycombs, and voids in concrete structures. It cures into a constant volume material that neither shrinks nor swells. Ideal for water tanks, tunneling, sewage, basements, and other structures exposed to moisture.
Uses / ApplicationsFilling and sealing cracks, joints, and honeycombs in concrete Pipe intrusions, leak points in pipe penetrations Water tanks, sewage, tunnels, dams, manholes Concrete defects in both dry and wet concrete surfaces
FAQ (Questions & Answers)
Q1. How fast does CYH-500 set / react?Gel time is ~110 seconds (25 C) when resin:water is 2:1 ratio. Induction is ~15 seconds. Q2. Will it shrink after curing?No. It cures to a constant volume, with no shrinkage or swelling after cure. Q3. Can it be used under flowing water / wet concrete?Yes it's hydrophobic and bonds well to wet surfaces. Negative-side application also possible. Q4. What is its expansion capability?When mixed in resin:water ratio ~10:1, expansion up to ~27-30 (2700 %) is possible.
Q5. What conditions are needed (temperature, surface)?Substrate & ambient temperature should be 5 C. Store product in dry, cool place. Apply on clean surfaces. Work in moderate conditions for better performance. Q6. How much will 20 kg cover / fill?Depends entirely on crack size, depth, width, amount of water mixed. Because it expands, a small volume can fill larger voids. As a rough estimate, for very fine cracks maybe few linear metres; for cavities depends on expansion ratio and injection methodology. Better to do a mock-trial.Q7. Approx price?Please visit CIVILIZEMART

Exceptional Waterproofing for Concrete and Masonry

CYH 500 is engineered to handle the toughest waterproofing challenges in both new and existing concrete and masonry substrates. It reacts quickly with water, expanding to fill and seal even intricate cracks and voids. Its robust chemical and hydrostatic resistance ensure protection and durability in demanding industrial environments.

Simple, Ready-to-Use Application

This single-component, hydrophobic polyurethane resin requires no pre-mixing or complicated preparations. Simply inject it using a PU grouting pump or cartridges, making installation straightforward and efficient-even under wet and actively leaking conditions.

FAQ's of CYH 500 SINGLE COMPONENT HYDROPHOBIC PU:

Q: How is CYH 500 polyurethane applied for sealing cracks and voids?

A: CYH 500 is injected directly into cracks, joints, or voids using a PU grouting pump or cartridges. No pre-mixing is required; simply use the ready-to-use liquid resin, which reacts and expands upon contact with water to seal the targeted area.

Q: What are the main benefits of using CYH 500 for waterproofing?

A: CYH 500 offers fast reaction and expansion, strong adhesion to concrete and masonry, superior chemical and hydrostatic resistance, and secure sealing in wet or actively leaking conditions. The cured foam is durable and non-toxic, making it safe for industrial and structural applications.

Q: When does CYH 500 start curing, and how long does it take to fully cure?

A: The curing process begins within minutes once CYH 500 comes into contact with water. It reaches full cure in 24 to 48 hours, depending on environmental conditions and the amount of moisture present.

Q: What storage conditions are recommended for CYH 500?

A: To maintain product integrity, store CYH 500 in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed until ready for use, as the shelf life is 12 months in unopened packaging.

Q: In what situations is CYH 500 most effectively used?

A: CYH 500 is ideal for sealing and waterproofing cracks, joints, and voids in concrete and masonry, especially where water ingress is problematic, such as basements, tunnels, water tanks, and underground structures.

Q: What makes CYH 500 suitable for wet and leaking environments?

A: CYH 500 is hydrophobic and tolerates moisture, reacting rapidly and expanding in the presence of water to effectively seal leaks-even under active water flow conditions.
