Slurry Seal is the application of a sealing coat to prolong the life of the existing materials. We use this process on surfaces which are still structurally sound but showing signs of deterioration. It is designed to seal the existing surface to stop water penetration which can lead to failure of the surface which would then require full reconstruction to be needed. It is a …8.1.2 Purpose of a Slurry Seal A slurry seal is a thin surface treatment that is laid in a thickness equal to the largest stone in the grading of its component aggregate. It may include either a conventional or polymer modified emulsion, and the slurry seal may be slow or quick setting. The emulsion is usually cationic in nature, but may be ...
