Slurry Seal is very similar to micro-surfacing. Slurry seal is an extremely versatile pavement tool used for preventive maintenance and preservation. This asphalt surface provides a very durable, skid resistant finish. A popular method of placing slurry seal is with a process known as cape seal. Cape seals are a combination of AST underlayment overlaid with a slurry seal. With this process we are able to address a broader range of distressed (cracked) pavements.
