Types of Joints in Concrete Construction – theconstructor.org
Joints in concrete construction are construction, expansion, contraction and isolation joints. These joints are placed in concrete slabs and pavements at regular intervals to prevent development of cracks in concrete.
Wall contraction joints often are made by fastening projecting strips inside forms to create narro w g r ooves in the concrete (Figure 1). P r ojecting strips are made of wood, p r emolded plastic, or metal. When using wood strips, a sawcut on the form side of the strip re d u c e s swelling that might damage concre t e near the joint area.
