Hydrocor Corkjoint - Type 3 Self Expanding Cork Filler

Hydrocor Corkjoint Type 3 is a self-expanding cork filler used for forming and filling expansion and static joints. Made from cork granules bound together with insoluble synthetic resin, it expands when exposed to moisture and provides semi-rigid, void-free backing for elastomeric sealants subject to hydrostatic pressures. Ideal for filling joints in concrete roads, bridges, carparks and other internal or external traffic areas.
