UHPC was utilized for the Capilano View Cemetery Columbaria Roof Panel project in West Vancouver, B.C. The panels were required to span 17 feet in a region with significant snow loads and ice while maintaining a minimal profile. With a compressive strength of up to 25,000 psi and flexural strengths up to 6,000 psi, the system was strong enough to support the long span.
The roof consisted of six precast panels, each weighing 2,200 pounds. The underside of each panel was cast down in a mold made of wood and coated in a special polyurethane enamel, which allowed the UHPC to exhibit a marble-like shine. The top side of the panel was hand-finished.
The cost of the six Ductal panels was nearly half of a stainless steel roof system similar in shape. Another advantage to the UHPC roof panels was their light weight – a conventional concrete roof would have weighed 4,000 to 6,000 pounds more..
