Underwater epoxy systems are the right choice when the job needs stronger bond, a denser cured body or more controlled structural repair below the waterline. Compared with bulk cementitious placement, epoxy routes are usually selected when the repair zone is smaller, the bond requirement is higher, or the project needs a more compact and chemically resistant repair body.

ZRETE’s underwater epoxy route combines two practical systems. EGM-100S Underwater Epoxy Grout is used for dense submerged filling and jacket-based rehabilitation, while ZRETE Underwater Adhesive is used for wet-surface or underwater bonding, anchoring and structural repair work on concrete, steel and masonry.

When epoxy is the right route

• Submerged structural filling that needs a denser repair body

• Jacket-based pile rehabilitation and encapsulation systems

• Wet-surface or underwater bonding to steel and concrete

• CFRP, steel plate bonding or anchoring in high-humidity zones

• Marine and submerged repair work where chemical resistance matters

Recommended product matrix

Why this route works

• Higher bond and denser cured body than bulk cementitious routes

• Suitable for submerged interfaces where adhesion is critical

• Useful for jacket repair systems, steel bonding and underwater strengthening

• Good fit for marine or wet repair zones needing compact structural repair

Typical applications

• Submerged pile and pile-cap rehabilitation

• Jacket-assisted marine repair and protective filling

• Wet or underwater steel plate bonding

• Underwater CFRP and anchoring-related repair work

• Dense filling of damaged or spalled underwater structural zones
