Slurry seal forms a long-wearing, rock hard surface that provides years of use for both old and new roadways and parking lots. Slurry seal from asphalt is designed to extend the life of existing pavement by protecting the under-surface from the effects of oxidation, weather and water seepage.
Slurry seal is an asphalt slurry mixture made from closely graded fine aggregate, emulsified asphalt and water, all carefully calibrated and mixed to form a mortar-like compound. This mixture is designed for easy and efficient spreading as a sealer on streets, playgrounds, parking lots and driveways. Slurry seal fills all voids, cracks and eroded areas. This heavy coat serves as a proven sealer and an extremely durable, non-skid surface.
The preparation process
The asphalt area will be thoroughly cleaned using a power sweeper or power blower to remove all dirt and loose particles. All weeds and vegetation are eliminated. Grinding, torching, scarifying or scraping with a shovel will remove the accumulation of oil and grease in car stalls. These may adversely affect the slurry seal bonding. An application of poly-oil seal will be applied to extreme areas and then blotted with sand to ensure the best the best chance of bonding between slurry seal and heavily greased-soaked oil spots.
Slurry seal will then be applied with trucks mounted with continuous mixing machines. These trucks are large and not easily maneuvered in tight areas. Ensure all vehicles are parked well off the work areas. When applying slurry seal to small areas we use hand squeegees and other tools. The drying time for slurry seal is approximately 3-6 hours or longer depending on weather conditions. Ensure everyone stays off the material until the barricades have been removed.
