Expansion Joints play a big role in the integrity of big structures. They're used to keep the expansion and contraction, of two adjoining building materials under control. They safely hold these parts together. They're also supposed to allow movement, while facing seismic activity or underground settlements.

Concrete and Metal structures can contract and expand, due to high and low temperatures. This causes cracks and damage to the asset. This is why there's a multitude of expansion joints. They're used in many different places, as per the need.

Along with the joints themselves, you also need a sturdy yet flexible sealant. These are used to fill the gap between expansion joints, and further reduce the chances of damage, due to expansion or contraction (for instance: compression seal, epoxy expansion seal, neoprene foam seal, etc). Similarly, Expansion Joint Cover Plates are used for covering floor surfaces using expansion joints, where necessary. This can be, for instance, for evening out the floor.

DSM System is a primary seal for deck expansion joints. Neoprene foam is a closed cell foam. It is a highly impenetrable for various materials. Hence, it proves to be a high quality seal. Works against water, air, and other liquids.

Backing rods are used in combination with sealants. Their purpose is to control the sealant's depth during installation. Backing rods ensure that just the right amount of sealant is utilized, for joints. This way we save the material from wastage, while also deterring any possibility of cohesive failure. 

Some examples of their uses, are shown below. You can easily see the various applications we have for these systems:
