Every structure, regardless of size, height and width moves and to accommodate such movements, cushion their effects, maintain their integrity, elastic joints are provided at various strategic locations throughout the exterior of the structure. The dimensions and locations of the joints are directly related to the tolerance, thermal movement charecteristics of various components that make up the structure, potential shrinkage and design aesthetics.

CHEMISTIK sealants are primarily used in joints in order to prevent passage of water or air, to absorb expansion or contraction movements and to prevent intrusion of foreign matter which may impede movements.

CHEMISTIK Sealants are of various types like high performance which can accommodate movements of  25% or more and normal performance types that can accommodate movements upto --12.5%..

The selection o the correct sealant is very important and it's selection will depend on the movement characteristics of the structure.
