What Are Stone Foundations?
Stone Foundations Explained
What Are They?: A stone foundation is made from natural stones stuck together with a mix called mortar. Long ago, before the 1900s, many homes were built on these strong foundations. They last a long time and keep homes warm.
Types of Stones Used: Builders used different kinds of stones like granite, limestone, sandstone, and fieldstone. The mortar that holds them together is a mix of lime, sand, and water.
Where You Find Them in Canada: Stone foundations are common in old homes, especially in places like Ontario, Quebec, and the Maritimes.
How to Tell If Your Stone Foundation Is Damaged
Cracks: Look for cracks between the stones. They can be horizontal, vertical, or shaped like stairs.
Water Problems: Mold, wet spots, or damp patches mean water is getting in and can damage the stones and mortar.
Walls Not Straight: If walls are bowing or leaning, it means the foundation needs fixing right away.
How to Check for Damage
Simple Checks You Can Do
Walk Around: Walk around your home to spot any cracks or water damage inside and outside.
