How to Prepare a Substrate Before Pouring Concrete for Long-Term Performance
Preparing the substrate (the “subgrade”) is the most critical factor in preventing premature slab failure. Long-term performance—avoiding cracking, settling, or heaving—relies on a foundation that provides uniform support and moisture control. In the Canadian climate, where freeze-thaw cycles and groundwater movement exert significant stress on concrete, adhering to proper subgrade…
