About Foundation Types

Selecting the right foundation type is crucial for the stability and longevity of your structure. Foundations distribute the building's weight to the ground and provide a level surface for construction.

Types of Foundations
  • Concrete Slab: A flat concrete pad that provides a stable base for structures. Common for garages, sheds, and homes in warmer climates.
  • Footings: Typically used to support walls or columns. Made of concrete that extends below the frost line to prevent shifting during freeze/thaw cycles.
  • Stem Wall: A foundation consisting of footings and a short wall that supports the structure. Common in colder climates and for homes with crawl spaces.
  • Pier Foundation: Consists of cylindrical concrete columns that support the structure. Used for decks, elevated homes, and buildings on sloped or unstable ground.
Foundation Materials Considerations
  • Concrete strength should be appropriate for local soil conditions and building loads.
  • Reinforcement prevents cracking and increases tensile strength of the concrete.
  • Vapour barriers prevent moisture from seeping through the concrete, which is important for interior living spaces.
  • Gravel bases provide drainage and a stable foundation for the concrete to be poured on.
  • Always check local building codes for minimum requirements for your specific area and project.
