Because Calgary experiences significant temperature fluctuations, moisture changes, and clay soil movement, garage foundations must be carefully designed to prevent shifting and cracking over time.

The correct foundation depends on several factors including the size of the garage, its height, soil conditions, and how the space will be used. In many cases, garages under approximately 600 square feet can be built on a properly prepared slab-on-grade foundation. Larger garages or structures designed to support additional loads may require engineered solutions such as grade beams, frost-protected footings, or screw piles.

At Alta Home, proper base preparation is essential. Every garage foundation we build includes carefully compacted base material, a 10-mil vapour barrier to prevent moisture migration, and 2-inch rigid insulation to help reduce frost movement and improve long-term slab stability.

We evaluate the specific conditions of each property to ensure the foundation is properly designed for durability. The appropriate foundation type is always included and clearly specified in the quote you receive for your project.
