Expansion Joints

The greatest deformation trigger is the temperature. The larger the structure, the more it moves, and the predefined deformation joints allow the cast concrete to expand and shrink according to temperature changes. 

When dealing with buildings with a single concrete plane of more than 40 meters or which must withstand movement from the ground, we need to use a deformation joint. Deformation joints provide mobility for the structure, but up to 40 meters of concrete can also be poured without deformation.

Several ways and materials make deformation joints watertight, such as acrylic resins, PVC joint profiles, suitable joint mastic sealants, glue joints, and polyurethane resins.

For an excellent performance, it is also necessary to cover the filling materials of the joints with polyurethane mastics or polysulphide mastics or with a sealant suitable for the situation.

When the joint is waterproofed with acrylic resin, the work is finished with the joint sealant. The resin material is not mechanically durable or beautiful. Sealants make the deformation joint look nice and mechanically durable.
