Ever wonder what those historic houses were built from? It’s not concrete…then what is it? It’s Lime mortar. What in the world is lime mortar? Join us to find out!

The National Trust of Trinidad and Tobago is hosting a workshop entitled “Using Lime Mortar: Historic Restoration Workshop” on May 17th from 8:30am to 4:00pm on lime in historic buildings and restoration. Andrew L. deGruchy, of LimeWorks USA will lead the programme. This workshop targets architects, engineers, and masons, as well as anyone with historic building built with lime mortar who wish to know more about the material and conduct repairs.

Most of Trinidad and Tobago’s historic buildings and heritage sites are built using lime mortar. Lime mortar is a type of mortar composed of lime and an aggregate such as sand, mixed with water. Essentially, lime is calcium oxide or calcium hydroxide. It is one of the oldest known types of mortar, dating back to the 4th century BC and is abundant in Trinidad and Tobago.
