Case Study: Sump Pump Installation to Prevent Groundwater Seepage in Richmond Hill

Location: Richmond Hill, Ontario
Client: The Nguyen Family
Service: Sump pump system installation
Problem: Groundwater infiltration through basement slab and cold joints

The Challenge

The Nguyen family contacted Direct Waterproofing after noticing water pooling along the edges of their unfinished basement floor during spring thaw. Their property, located near a water-retaining green space, was experiencing hydrostatic pressure that caused water to seep up through cracks and cold joints in the slab.

Although no visible cracks in the foundation walls were found, moisture meters confirmed elevated humidity and active seepage from below. The home had no existing sump system in place to relieve groundwater pressure.

Our Solution

We recommended installing a complete sump pump system with a sealed basin and discharge line to effectively capture and redirect rising groundwater.

Scope of Work:

• Subfloor Excavation: Broke through the concrete slab in a designated corner to create a pit.
• Sump Pit Installation: Installed a perforated sump basin to collect groundwater from the surrounding gravel bed.
• Pump Installation: Equipped the system with a high-efficiency, automatic submersible pump.
• Discharge Line: Routed a discharge pipe outside the home, complete with a backflow preventer and freeze protection.
• Sealing and Cleanup: Resealed the concrete and ensured all components were flush and unobtrusive.
  

The Result

Following the installation, the family experienced no further water seepage even during heavy spring rain. The sump pump activates reliably during wet conditions, and the sealed basin helps maintain air quality and safety.
