Why crack expansion joints?

    If you have a business that has concrete floors, you might have areas that have expansion joints. Expansion joints are used to help take the pressure off of building materials, such as large concrete areas.  It provides flexibility to the surface to allow for movement when temperatures change, or from surface load use.  

Concrete is subjected to shrinkage due to loss of moisture in it at the time of drying, which results in the formation of cracks in the structure. To avoid these cracks, contraction joints are sometimes  cut cracks with a walk-behind concrete cutting saw machine on concrete.

Expansion Joints can also be used in many other places, not just on floors.

They are used in or on:

· Bridges

· Buildings (exterior & interior)

· Parking Garages
