Toronto’s constant freezing and thawing causes soil movement that shifts interlock, cracks concrete, and weakens retaining walls. Proper base prep and drainage prevent these issues.
We recommend:
Compacting base gravel in layers.
Maintaining a 2% slope away from foundations.
Using high-quality polymeric sand to block water infiltration.
Whether you’re in Forest Hill, North Toronto, Midtown Toronto, or Rosedale, freeze–thaw protection keeps your investment stable year-round.
