DESPITE THE FACT THAT joint sealants are only a very small part of the overall cost of a construction project, they play an absolutely crucial part in keeping a building air and watertight, in order to prevent serious damage and a loss of thermal insulation. The costs of which can obviously be considerable. Therefore the right joint sealant selection is also critical to maintain this function over the whole service life of the structure. This is also becoming increasingly important in the drive towards energy efficiency and sustainability in construction.

Within a construction project there are many different types of joints that require efficient watertight sealing, including all of the isolation, sanitary, construction and movement or expansion joints in the facade and throughout the structure.

Sika’s extensive range of joint sealants includes products and systems for all of these different joints that will ensure optimum performance and durability.
