Introduction: Securing the Pivot Points of Navigation Gates

Miter gate hinges—pintles and quoin blocks—are the pivot points that allow massive gates to swing open and closed. Their embedments must transfer enormous concentrated loads to the lock chamber structure. Traditional cementitious fills develop cracks and gaps under cyclic loading, compromising gate alignment and operation. FLD’s epoxy resin filling material for miter gate hinge embedments provides a proven, long-lasting solution.

Core Benefits

Concentrated Load Capacity

Compressive strength exceeding 80 MPa handles the extreme point loads at hinge locations without crushing or creep.

Gap-Free Interface

Shrinkage-compensated formulation maintains intimate contact with embedment surfaces, preventing the gaps that cause gate misalignment.

Steel Protection

Impermeable to water, protecting embedment steel from corrosion that weakens hinge capacity over time.

Cyclic Loading Endurance

Maintains properties through decades of gate opening and closing cycles, ensuring consistent performance.

Key Features

High Bond Strength

Bonds permanently to steel embedments and concrete, creating a unified load-transfer system.

Flowable Placement

Self-leveling consistency fills complex embedment geometries completely, without voids.

Temperature Tolerance

Performs from -20°C to 60°C, accommodating seasonal temperature variations in lock structures.

Fast Construction Schedule

Reaches design strength in 24-48 hours, supporting efficient project timelines.
