Why Newmarket Homes Need Waterproofing
Ontario’s freeze-thaw cycles, spring snowmelt, and summer storms put constant pressure on Newmarket foundations. The sandy clay and silt soils common in the area retain moisture and create hydrostatic pressure against basement walls. Proactive waterproofing protects structural integrity, indoor air quality, and property value.
