Introduction: Protecting the Critical Interface Between Gates and Structures

Lock gate bearing pads transfer enormous thrust loads from operating gates to the lock chamber structure. These high-stress interfaces demand grout materials that combine strength, precision, and long-term durability. FLD’s high-performance epoxy grout for lock gate bearing pads provides engineered solutions trusted by hydraulic engineers worldwide.

Core Benefits

Maximum Load Capacity

Compressive strength exceeding 100 MPa ensures bearing pads transfer their full design load without grout crushing or creep.

Precision Thickness Control

Non-shrink formulation maintains designed bearing pad elevations, critical for proper gate alignment and seal effectiveness.

Steel-to-Concrete Bond Excellence

Bond strength to both materials exceeds 15 MPa, creating an integral bearing system that does not separate under cyclic loading.

Fatigue Resistance

Maintains properties through millions of load cycles from gate operations, preventing progressive degradation.

Key Features

Ultra-High Strength

100+ MPa compressive strength exceeds structural concrete, ensuring grout never limits bearing capacity.

Non-Shrink Performance

Expands slightly during cure to compensate for thermal contraction, maintaining full bearing contact.

Rapid Strength Development

Reaches operational strength within 24 hours, minimizing construction delays.

Water and Chemical Resistance

Impermeable barrier protects bearing pad interfaces from corrosion-inducing moisture and chemicals.

Application Areas

• Miter gate bottom pintle bearings
• Top hinge bearing blocks
