Sump Pump Installation and Waterproofing in the Basement in Sainte-Thérèse, QC
Challenge
Mr. Melios was facing major issues with his sump pump system, which was noisy, unreliable, and frequently stopping. These malfunctions were causing him significant concerns, particularly during heavy rains or the spring thaw. He wanted a durable and effective solution to protect his basement from water infiltration or flooding.
Resolution
Mr. Melios contacted Sous-Sol Confort for an assessment of the situation and to explore the best available options. After a thorough inspection, our specialists recommended installing our Double Protection sump pump system. This system includes the following elements:
- Installation of an Interior Drainage System:
- Installation of a French drain inside the basement to prevent the accumulation of debris and soil, often responsible for clogging traditional drains. This system ensures easy maintenance and optimal drainage.
- Waterproofing of the Walls:
- Application of the Delta MS membrane on the basement walls, creating a waterproof barrier against moisture and preventing future water infiltration.
- Replacement and Upgrading of the Sump Pump System:
- Installation of a Zoeller cast iron sump pump with ⅓ HP, capable of evacuating up to 8,500 liters of water per hour, even at a height of 8 feet.
- Addition of an integrated basin in the ground to accommodate the pump system, optimizing its efficiency.
- Installation of a battery-powered alarm that automatically triggers when the water level exceeds the normal activation threshold of the pump.
- Installation of a sealed cover to prevent moisture evaporation and ensure better waterproofing.
- Safe Water Evacuation:
- Installation of an independent SafeGard discharge line, allowing water to be reliably and continuously evacuated outside the house, even in the event of freezing or blockage.
Result
Thanks to this comprehensive solution, Mr. Melios now enjoys a basement fully protected against water infiltration and flooding, even during power outages. The Double Protection sump pump system ensures optimal performance and peace of mind in the long term.
