FIELD GUIDE TO CONCRETE REPAIR APPLICATION PROCEDURES
Methacrylate Flood Coat
Flood-coating a concrete slab using methacrylates is used when there is a need to fill and bond small cracks, such as shrinkage cracks, as well as to seal the slab against the penetration of water, salts, or deleterious chemicals. Methacrylates have the added benefit of repairing some cracks and improving resistance to traffic wear. Cracks bonded using methacrylates can usually resist stresses caused by traffic vibration, but not structural stresses. Prior to installation, special care should be taken to ensure the cracks are open, clean, and free of any contaminants or other bond-inhibiting materials such as oil and grease. If structural repair of cracks may be required, consult a qualified structural engineer for evaluation. Ensuring a full-depth structural repair using gravity feed methods can be difficult, and although vacuum injection of methacrylates can be done, pressure injection using epoxies may be a preferred option (see RAP Bulletin 1, “Structural Crack Repair by Epoxy Injection”).
