Case Study: Sump Pump Installation to Prevent Groundwater Seepage in Oshawa

Location: Oshawa, Ontario
Client: The Stewart Family
Issue: Groundwater entering basement during high water table periods
Service: Sump pump installation with sealed pit and discharge system

The Challenge

The Stewart family lives in a two-storey home in north Oshawa, built in the late 1990s. Over the past year, they noticed water pooling along the basement floor’s edges during spring and fall, especially after extended rainfall. Although the home had no visible wall cracks, the moisture was consistent—suggesting groundwater pressure from a high water table.

They had no sump pump or existing interior drainage system in place. Concerned about future water damage and mold risk, they contacted Direct Waterproofing for a long-term solution.

Our Solution

After a moisture mapping inspection, we determined that a sump pump system was the ideal first step to manage water pressure beneath the foundation slab. We proposed a subfloor sump pump installation with sealed components and optional alert monitoring.

Installation Steps:

• Sump Pit Excavation: Identified the lowest point of the basement slab and excavated a sump pit sized for a high-efficiency pump system.
• Pump Installation: Installed a 1/3 HP submersible sump pump, capable of handling high volumes of water with minimal noise.
• Sealed Sump Basin: Installed a durable, sealed sump liner with airtight lid to minimize humidity and debris entry.
• Discharge Line Routing: Ran a discharge pipe out through the foundation wall and away from the house, terminating with a freeze-resistant extension and backflow preventor.
• Optional Add-On: Connected a battery backup alarm system to notify the homeowner in case of pump failure or power outage.

The Result

Since installation, the Stewart family has experienced a completely dry basement—even during multiple storms and the spring thaw. The sump pump activates automatically and quietly, and the family expressed relief that their foundation is now protected from seasonal moisture fluctuations.

Client Testimonial

“Our basement used to smell damp and feel humid every spring. Since the sump pump was installed, it’s been bone dry. Direct Waterproofing was quick, professional, and explained every step. We couldn’t be happier.”

Frequently Asked Questions

1. Does every home in Oshawa need a sump pump?
Not necessarily. But homes in areas with high water tables, poor exterior drainage, or recurring basement dampness benefit greatly from having one installed.

2. Where is the sump pump installed?
We install the pump below your basement floor in a sealed pit. It automatically activates when water levels rise and pumps the water safely outside.

3. How long does installation take?
Most sump pump installations are completed in one day, including pit excavation, pump setup, and discharge pipe installation.

4. Will I need a battery backup?
We recommend it—especially if your area is prone to power outages. Battery backup systems ensure your pump continues working when you need it most.

5. Is sump pump installation noisy or messy?
The process is controlled and contained. After digging and installing the pit, we restore the concrete floor neatly. The pumps themselves are quiet and unobtrusive during operation.
