Waterproofing Markham

Markham's rapid development (1990s-2010s) often placed subdivisions on former farmland with naturally high water tables and clay soils. Many builders didn't anticipate the long-term drainage challenges of converting agricultural fields to residential areas. The Rouge River watershed also creates consistently elevated groundwater levels.

Markham's clay soils retain water and create significant hydrostatic pressure against foundations. We use specialized drainage systems including aggressive gravel drainage layers, high-capacity pumping systems, and clay-specific waterproofing membranes designed for these challenging soil conditions.

Yes, we specialize in culturally sensitive restoration for Markham's significant Chinese-Canadian heritage properties, including historic temples, community buildings, and traditional architecture. We work with heritage consultants to ensure appropriate materials and methods are used while meeting modern waterproofing standards.

The Rouge River watershed creates seasonal flooding challenges throughout Markham. We install comprehensive flood protection including backwater valves, emergency pumping systems, and specialized drainage designed for the area's seasonal water level fluctuations and storm water management requirements.

Markham's subdivisions often have complex drainage interdependencies between properties. We assess whole-neighbourhood drainage patterns, coordinate with municipal storm systems, and install solutions that work within the planned community infrastructure while protecting individual properties.
