Many historic masonry buildings which are over 100 years old are just receiving their first repointing work. These old buildings were usually built with only lime and sand for mortar. The well built historic buildings are considered sustainable due to the longevity of their service as opposed to the waste caused by rapid cycles of obsolescence in buildings such as the modern strip mall.
The details in how all substantial and beautiful historic masonry buildings were made allows many of these old structures to last for centuries and even for millennia throughout the world. Modern Portland cement mortars have had many known failures as a primary or gauged-in binder to lime mortar used in masonry preservation efforts of these old masonry buildings.
However, the correct lime and sand mortar mix has always been very durable and cost effective by achieving its long service life for the buildings they serve. When new mortars with duplicate properties as that of old materials are used to repair and repoint buildings, or to build new ones, then the final life-cycle assessment of the replacement materials will be as equally impressive as that of the historically time-proven materials. Using materials with an outstanding durability in their service life is a property of Green Building Technology.
Our environment has been saved from approximately 271,256 lbs. of CO2 released into the atmosphere due to the choices our customers made to use our "Eco-friendly" Natural Hydraulic Lime that replaced Portland Cement as a mortar and stucco's binder. Last updated 11-1-2014
