An expansion joint is used in construction to help deal with the effects of building materials expanding and contracting. They can be purchased through hardware stores like Home Depot.
What else can I help you with?
Does concrete expand?
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
What is the general cost for replacing the sealant and backer rod on expansion joints?
what is the general cost for sealant replacing in expansion joints
Expansion Joints?
Expansion Joints are installed in the piping system to absorb vibration and shock. They also have the Advantage of reducing noise and compensating caused by misalignment.
What happens to a bridge's expansion joints on a hot day?
If there is no expansion joints on a bridge and if it's really hot the molecules of the bridge will be separated slowly and the bridge will collapse
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
Why do roads have expansion joints?
so they can prevent it from breaking
What is the control joints?
Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).
What is the maximum size a concrete slab can be without the need for expansion joints?
The maximum size for a concrete slab without needing expansion joints is typically around 100 to 150 feet in either direction. Beyond this size, expansion joints are usually necessary to prevent cracking due to temperature changes and shrinkage.

Hangers used when thermal horizontal movement is a factor with piping?
Expansion joints are typically used when thermal horizontal movement is a factor with piping. They allow for movement in the horizontal direction to accommodate thermal expansion without putting stress on the piping system. These expansion joints can come in various forms such as bellows or slip joints.
Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
What are the two types of joints in construction?
Expansion joints. Butt,lap,half-housed,mortise/tenon and mitre joints to name some common ones.
