A.: You'll need isolation joints (also called expansion joints) where the lot meets any building, light pedestal, or other fixed object. According to Dale Diulus of Phoenix Cement Company, however, you won't need any expansion joints in the 80x200-foot section. Contraction joints at 8- to 10-foot intervals should accommodate any slab movement ...

Concrete expansion joints are primarily utilised to compensate for expansion and shrinkage in concrete due to temperature changes and other factors. After concrete is poured and moulded into shape it will harden and set which naturally causes a reduction in volume. Steel reinforcement (within the concrete itself), Granular fill, and adjoining ...

Attach tear-side-up to the adjacent material before pouring next concrete section. Attachment can be made with construction adhesive, nails or staples. Be sure that the top of the expansion joint is set at the top of the intended concrete pour. Expansion Joint material includes a built-in "tear-off" strip.

Consideration and location of exterior expansion joints are important. Fascia and soffits should be designed with expansion joints in mind, especially in severe climate extremes. Expansion joints can also be the basis of a geometric design. A good example of this would be an expansion joint every 10 feet on stucco soffits.

Just a general question about expansion joints. I just had my driveway and concrete pathway done, and the concreter has saw cut expansion joints into the concrete. Is there a need to fill the expansion joint hole that has just been cut? Currently it just has an open gap left from the saw cutting. Thanks in advance Cheers

Movement joints are also useful when laying concrete within an area bounded by walls or buildings, or when an object such as a manhole cover has to be incorporated within the slab, as they allow the concrete to expand and/or contract without transferring pressure onto the other structures, causing cracks within the concrete slab, or the wall, MH cover, etc.

They all relieve contraction stresses in the concrete. Since contraction joints generally open somewhat as the slab cools and hardens, some space develops at each joint for later pavement expansion. If all foreign material is kept out of these openings, the contraction joints also serve as expansion joints, making regularly spaced expansion joints

Concrete expansion joint. A concrete expansion joint or isolation joint is a gap that allows the concrete to expand and contract when the temperature changes. Expansion joints form a break between the other parts of a structure and concrete to allow movement without causing stress in concrete, leading to cracking.
