Expansion Joints
Building faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Without expansion joints, these structure would crack under stress.
Royalty Sealants installs expansion joints that are design to hold parts together while safely absorbing temperature induced expansion and contraction of building materials, vibrations, or movement due to ground settlement or seismic activities.
Expansion joints can be installed vertically or horizontally. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
Concrete Control Joints
Control joints are used in concrete masonry to reduce the occurrence of shrinkage-related cracking. A control joint is a continuous vertical joint filled with mortar, but with a bond breaker on one side to reduce tensile stress across the joint.
A concrete masonry wall may crack if control joints are not provided as it shrinks over time. Control joints widen as the concrete masonry shrinks, preventing it from cracking. Control joints should be provided at regular intervals along the wall’s length and near corners, returns and changes in the wall’s height, support or stiffness. Control joints will not relieve masonry expansion.
