Concrete Crack Repair  
Concrete cracks will get worse if left untreated. It is best to fix the cracks as soon as they appear or damage will increase and concrete may need to be replaced. The three best options for concrete crack repair are epoxies, polyurethanes and concrete slurries. With concrete slurries, the cracks must be widened first to properly anchor the repair and the repair must be kept damp to prevent further cracks. Polyurethanes need a clean dry surface for a solid bond; simply squeeze the cartridge and fill the crack. Epoxies often require a primer. Follow the directions on the package and fill in the cracks.
