Local basement waterproofing for Newmarket
Newmarket sits at the south end of Lake Simcoe in clay-heavy York Region soil. That soil is where the basement waterproofing story starts. Clay holds water against foundations longer than sand or loam, which means hydrostatic pressure here is meaningfully higher than in regions like Aurora-east or Markham-south. A waterproofing system that overperforms in lighter soil can be undersized for Newmarket.
The town has three rough housing eras that each bring their own basement issues: pre-war stock in the original downtown grid (Old Newmarket between Main, Davis, and Eagle), 1970s-90s subdivisions (Stonehaven, Glenway, Bristol-London), and post-2000 builds in the north and east (Copper Hills, Summerhill Estates, Woodland Hills). The fixes are different for each.
We work in Newmarket constantly, which means tight coverage and short travel times for inspections and follow-up visits.
Newmarket water and soil context
Newmarket's clay soil and proximity to the East Holland River and Lake Simcoe watershed mean groundwater levels stay high for longer after rain or thaw. Areas south of Davis Drive (closer to the river floodplain) and parts of Old Newmarket that were built on filled-in marsh land have some of the highest hydrostatic pressure in York Region.
