Lime for masonry and rendering

Our architectural heritage is proof that lime is a material which guarantees that our buildings handed down from generation to generation and still visited or lived in will last for decades to come. Let’s continue to provide for the future !

Tradical Hempcrete

These hemp and lime self-insulating products regulate temperatures in summer and winter, control humidity and ensure the indoor air is of a healthy quality to breathe. These characteristics go above and beyond the expectation of current regulations and create an unrivalled system.
