Advanced Waterproofing Solution

PU/Epoxy Injection Grouting delivers a powerful waterproof membrane for both structural repairs and preventive maintenance. Its hydrophobic nature ensures minimal water absorption, making it ideal for use in demanding environments requiring robust moisture protection.

Versatile Applications

Ideal for sealing cracks and joints in concrete, this injection grouting is widely used in infrastructure like tunnels, sewers, and dams. Its liquid form enables deep penetration and effective sealing, protecting your structures from potential water damage.

FAQs of PU / EPOXY Injection Grouting:

Q: How is PU/Epoxy Injection Grouting applied to concrete structures?

A: PU/Epoxy Injection Grouting is injected into cracks or joints using specialized equipment. The liquid chemical fills voids and gaps, then cures to form a waterproof membrane, effectively sealing the targeted area.

Q: What types of projects benefit most from using PU/Epoxy Injection Grouting?

A: This grouting is well-suited for tunnels, dams, sewers, and other concrete structures that require reliable sealing of cracks and joints to prevent water penetration and structural deterioration.

Q: When should PU/Epoxy Injection Grouting be used during construction or repairs?

A: It should be applied whenever cracks or joints are detected, especially before signs of water leakage or after any structural movement that might compromise water tightness.

Q: Where can PU/Epoxy Injection Grouting be sourced?

A: The product is available globally through distributors, exporters, manufacturers, suppliers, and traders, with South Korea being a notable origin for quality variants.

Q: What is the process for injecting this chemical grouting?

A: The process involves cleaning the crack or joint, setting port injectors, and injecting the PU/Epoxy solution under controlled pressure to ensure deep penetration and effective sealing.

Q: What are the key benefits of using hydrophobic PU/Epoxy grouting?

A: Its hydrophobic property offers superior resistance to water ingress, enhances structural durability, and minimizes maintenance needs by preventing water-related damage over time.
