    The Best Caulking Material for Vertical Masonry

    To control the expansion and protect the wall structure from cracking under pressure, masons install vertical control joints at specific locations. These joints will absorb the pressure created by the expansion by giving the masonry wall flexible space to expand.

    Masonry Movement Joint Failures

    There are many types of masonry movement joints and movement control strategies, but the two most common are control joints in the concrete masonry unit (CMU) walls and expansion joints in clay stone veneers. In the past when CMU and stone walls were constructed as bonded composite walls, control joints and expansion joints needed to be coordinated and aligned through both the block and brick

    Movement joints are most commonly found between sections of building facades, concrete slabs, bridges, pavements, railway tracks, pipelines, and so on. In road construction,movement joints can be provided in the transverse direction to allow the expansion and contraction of a concrete slab due to temperature and subgrade moisture variation .

    What is the difference between an expansion and

    This usually means slabs, but could also mean cast in place concrete walls. The difference in them is that a construction joint is merely the location where you had to stop the pour. When you make the next pour it abuts directly to the previous one, and that joint is usually tied together buy rebar that extends through the joints. Expansion Joints occur between two separate pours but in this
