Two-Part Polysulphide can be supplied in pouring and gun grades for sealing horizontal and vertical joints where movement is expected, or where the performance specification is too rigorous for more common mastics and joint sealers. It is ideal for use in expansion joints in reinforced concrete structures such as bridges, reservoirs, water treatment works, sea walls and roads, etc. It can also be used in floors subject to heavy usage where a high resistance to damage is required.
