Sarooj

This project is an effort to recreate, document and test Sarouj using traditional methods. Sarouj is a type of lime-based mortar with very low water penetration that has been used across Iran in constructing buildings in direct contact with water, such as bridges, water reservoirs, ice houses, dams, and baths, for many centuries. It has also been employed due to its smooth and shiny surface for decorations (known as Sarouj Bori) and insulation. Furthermore, until the early 1990s, it was used as the main mortar for stone masonry structures in many regions of Iran, especially along the Zagros fringe, for building homes and interior spaces.

Crafting Sarouj entails a deliberate and intricate process, setting it apart from the swift and uncomplicated production of Portland cement. Because of the convenience associated with the latter, the knowledge of Sarouj making and application is fading fast, despite its notable durability, surpassing that of cement by a considerable margin. In this effort, we have been interviewing local builders in Qeshm Island, Iran, to document and recreate the making process of Sarouj .
