Population boom and worldwide space shortages have driven death-care industry entrepreneurs to become economical and efficient. The material of choice for the pyramids was limestone, but for present-day internment buildings, such as mausoleums, the staple product is precast concrete.
Modern, modularised precast crypts (vaults) are streamlined, efficient, durable and economical. They can be designed to support loads above (such as headstones and mausoleums). The elimination of formwork reduces the environmental impact to the surrounding area and helps protect workers from the dangers of cave-in.
