Ontario’s masonry heritage spans centuries, with older homes laid using lime mortar and modern buildings constructed with N-type mortar. Using the correct mortar is crucial for longevity and structural integrity.
Lime Mortar in Heritage Homes
Lime mortar, made from lime, sand, and water, is flexible and breathable. It allows historic buildings to settle naturally and prevents trapped moisture, which can cause damage. Unlike modern mortars, lime mortar expands and contracts with seasonal changes, reducing the risk of cracks.
N-Type Mortar in Modern Construction
Modern buildings use N-type mortar, a mix of Portland cement, lime, and sand. Stronger than lime mortar, it provides structural stability but lacks flexibility. While ideal for newer homes, it can damage heritage buildings.
Why Using the Right Mortar Matters
Applying N-type mortar to heritage homes can trap moisture and cause masonry to crack due to its rigidity. This mistake can lead to costly repairs and deterioration over time.
