Cape Seal in QLD

Colas Solutions are working on a Cape Seal project which is the application of a sprayed seal followed by a Microsurfacing layer. Cape seals have been around for many years and as the name suggests they were developed and first used in the Cape Province of South Africa. They are constructed by applying a single/single seal to the pavement followed by a Microsurfacing that can either partially fill the void space between the bitumen and the top of the aggregate, or completely cover the top of the aggregate. This is achieved by either a single or double application of Microsurfacing.
