Filling Concrete Expansion Joints
One of the activities of this group is to apply and fill the expansion joints. Choosing the proper materials according to the type of floor is very important because of adherence, strength and durability. In the case of concrete surfaces, proper materials should be used which have elastic properties and have good adherence to the surface. Also, in the case of metal joints such as bridges, in addition to adherence, expansion and contraction of floor and atmospheric conditions should also be considered.
