Expansion Joints
A permanent solution shouldn't be required for a temporary problem.
Concrete structures need to move. Concrete shrinkage, post-tensioning and temperature changes create movement that must be accommodated during construction. Traditionally, an expansion joint provides that freedom by permanently separating portions of the structure.
The Problem
The movement is greatest during the early life of the structure, but the conventional solution leaves a permanent joint in the building. That means sealants, covers, potential leakage and ongoing maintenance for the life of the structure.
A Better Solution
PS=Ø-EJ allows the structure to move during construction. After the building is enclosed and the appropriate initial movement has occurred, the reinforcement is connected to restore structural continuity, eliminating the permanent expansion joint where appropriate.
Eliminating the permanent open joint where appropriate also eliminates the associated sealant line, reducing the potential for leakage and ongoing joint maintenance.
Build Better.
