Lavafer | Rebar Corrosion Protection Slurry | MATEX

Lavafer is a high-performance, two-component cementitious slurry specifically engineered to protect steel reinforcement bars (rebar) from corrosion in concrete repair and maintenance projects. By applying a thick, alkaline coating directly to the steel surface, Lavafer restores the protective environment necessary for passive steel, effectively blocking the ingress of corrosive agents such as chlorides and carbon dioxide.

Key Features

• Corrosion Inhibition: Creates a robust physical and chemical barrier that prevents chloride penetration and carbonation, significantly extending the service life of the structure.
• Cementitious Composition: Based on cement and inert fillers, ensuring excellent adhesion to concrete substrates and compatibility with existing repair mortars.
• Easy Application: Designed for straightforward mixing and application using brushes or trowels, allowing for efficient on-site work without specialized equipment.
• Structural Integrity: Maintains the structural capacity of the reinforcement by preventing cross-sectional loss due to rusting.

Applications

Lavafer is ideal for use in the rehabilitation of aged concrete structures, bridge decks, marine environments, and industrial facilities exposed to harsh weather or chemical attacks. It is recommended as a pre-treatment layer before applying concrete repair mortars or protective coatings to ensure long-term durability.
