Concrete
Precast concrete panels
A more established process, precast concrete systems involve casting entire wall sections in a controlled factory environment before transporting them to the job site for installation. Each panel is poured into a reusable mold, often incorporating steel reinforcement, insulation, electrical conduit, and even architectural finishes like brick texture or stucco patterning, all in one step.
One of the biggest advantages of precast is construction speed. Once the panels arrive, the structure can go up quickly with minimal onsite labor. The precision of factory production also improves quality control and reduces material waste.
Precast concrete delivers exceptional durability. Reinforced with steel and designed to withstand fire, moisture, and high winds, these panels are built to last generations.
However, like any system, it comes with trade-offs:
■ Transportation logistics: large, heavy panels must be trucked in, adding significant cost, particularly for remote or distant projects.
■ Heavy equipment needs: cranes are typically required to lift and set the panels, adding cost and complexity. On tight or hard-to-access sites, this can be a nonstarter.
