Overview
McDowell Drain & Waterproofing recently completed a critical basement waterproofing and weeping tile replacement project for a Niagara Falls homeowner whose property was suffering recurring water intrusion and surface flooding. With over 45 years of experience and more than 3,500 successful projects across the Niagara region, our team delivered a tailored solution that resolved the issue once and for all—protecting both the interior living space and the exterior landscape.
Client Challenge & Initial Symptoms
The homeowner first noticed persistent dampness along the basement floor and a musty odor after even moderate rainfall. Within weeks, small puddles began to form beneath a concrete walkway leading to the front door—an early sign that the existing perimeter drain (weeping tile) was clogged or failing.
Key symptoms included:
- Surface water pooling on the lawn and sidewalk, threatening sub-slab leaks.
- Efflorescence (white mineral deposits) on the foundation walls, indicating hydrostatic pressure forcing moisture inward.
- Mold spores detected near the crawl-space entry, posing health risks to the family.
Given the home’s location near the Welland River and Niagara Falls’ notoriously high water table, these issues risked structural damage, wood rot, and compromised indoor air quality.
Our Expert Diagnosis
Our senior technician conducted a detailed site assessment, combining visual inspection with moisture-meter readings and a camera survey of the existing drain tile. This confirmed:
Key symptoms included:
- Collapsed weeping tile beneath the concrete walkway had become crushed under settling soil.
- Inadequate slope along the exterior grade was directing runoff toward the foundation rather than away.
- Sump pump capacity was insufficient for the volume of groundwater in that neighbourhood
With these findings, we recommended a multi-phased solution:
- Complete weeping tile replacement under both the lawn and the walkway
- Interior waterproofing by installing a new perimeter trench and high-filtration weeping tile wrapped in geotextile fabric.
- Upgraded sump pump system with battery backup to handle peak runoff.
- Exterior grading adjustments and downspout extensions to divert roof water.
Customized Solution & Installation Process
1. Site Preparation & Protection
To minimize landscape disruption, our crew:
- Laid plywood sheets over garden beds and lawn to protect turf.
- Covered concrete surfaces adjacent to the excavation zone.
- Set up safety barricades around the front walkway.
2. Weeping Tile Excavation & Replacement
- Excavated a continuous trench beneath the old sidewalk, exposing the collapsed drain pipe.
- Removed the damaged tile and replaced it with premium, filter-wrapped weeping tile designed to resist silt and root intrusion.
- Tied new tile into the existing sump pit and interior piping network.
3. Interior Waterproofing Enhancement
- Cut a narrow channel along the interior slab edge—linking it back to the sump pump system.
- Installed a gravel bed and perforated tile, then sealed any visible foundation cracks with polyurethane injection.
4. Sump Pump Upgrade
- Replaced the homeowner’s aging pump with a high-capacity submersible unit featuring a dual-float switch.
- Added a battery-backup pump to ensure 24/7 operation during power outages or heavy rain events.
- Tested the system under simulated high-flow conditions to confirm peak performance.
5. Exterior Grading & Finishing Touches
- Re-sloped soil away from the foundation to achieve a minimum 2% grade.
- Extended downspouts to discharge water at least two metres from the house.
- Re-paved the walkway and restored turf, leaving the property cleaner than when we arrived.
Results & Homeowner Satisfaction
Within hours of completion, the homeowner observed no further water seepage—even during a subsequent heavy thunderstorm. Key outcomes included:
- 100% elimination of surface pooling along the front walkway
- Stable, dry basement environment free from mold, efflorescence, or damp spots.
- Peace of mind thanks to the new sump pump’s battery backup and robust weeping tile system.
- Enhanced curb appeal with the unblemished concrete path and restored lawn.
The homeowner praised our team’s professionalism:
“McDowell’s crew was punctual, respectful, and explained every step. They treated my home like their own and wrapped up faster than I expected—now I can finally relax whenever it rains.”
