Abstract:
Successful planning, forming, and installation of expansion joints requires coordinated design and construction decisions before concrete forming and placement. This coordination includes: 1) establishing construction tolerances for formwork and concrete placement; 2) reviewing the manufacturer’s printed installation instructions (MPII) for the specified expansion joint; 3) estimating slab movements that will occur after forming and placement but before joint installation; 4) defining the installation timing; and 5) joint protection and repair. Effective coordination of these factors is essential to achieving successful expansion joint construction.
