Much of San Diego, California sits near the coast, where salt air and humidity act on outdoor structures over time. An outdoor columbarium in that environment needs materials and construction that resist moisture and weathering, since the structure is expected to stand and protect its niches for decades. Granite and quality precast concrete are chosen partly for this reason.
Drainage and siting also matter for a coastal columbarium, as standing water and exposure accelerate wear. Doric Vaults engineers its columbarium structures for outdoor installation and helps San Diego cemeteries account for the coastal conditions their memorial grounds face.
