Sump Pump & Weeping Tile Services in London, Ontario
Sump pumps and weeping tile are the backbone of below-grade drainage. We handle new installation, pump replacement, backup systems and footing drainage renewal to keep water moving away from your foundation.
How Foundation Drainage Works
Sump pumps and weeping tile work together to move groundwater away from the foundation. Weeping tile collects water at the footing and directs it to the sump pit, where the pump discharges it safely away from the building.
Together, these two components form a complete below-grade drainage system that protects your basement from hydrostatic pressure and water intrusion - even during heavy rainfall and spring snowmelt.
- Weeping tile collects groundwater at the footing
- Water flows to the sump pit by gravity
- The sump pump discharges it safely away from the home
Components of a Sump & Weeping Tile System

System Component
Sump Pump Installation
A properly sized sump pump is installed in a sealed basin to collect groundwater from the weeping tile and discharge it safely away from the foundation.
A properly sized sump pump is installed in a sealed basin to collect groundwater from the weeping tile and discharge it safely away from the foundation.
- Pump sized to your home's drainage load
- Sealed, airtight basin with gasketed lid
- Discharge routed away from the foundation
Failed or clogged weeping tile is replaced with new perforated pipe wrapped in filter cloth and bedded in clean drainage stone along the footing.
- Filter cloth prevents silt and root intrusion
- Clean stone ensures free water flow to the sump
- Restores footing drainage where tile has failed
Power outages often happen during storms - exactly when your sump pump is needed most. Battery backup and secondary pumps keep water moving when the primary pump loses power.
- Secondary pump activates on power loss
- High-water alarm alerts you before flooding
- Battery sized for extended outage protection
A check valve and properly routed discharge line carry pumped water away from the foundation so it doesn't recycle back into the sump pit.
- Check valve prevents backflow into the pit
- Buried line discharges well away from the wall
- Pop-up emitter or safe daylight discharge
Signs of Failed Weeping Tile
Failed weeping tile allows water to build up at the footing instead of draining away. Watch for these warning signs:
Water Seeping at Wall-Floor Joint
Groundwater pooling at the seam where the concrete floor meets foundation wall.
Sump Pit Running Constantly or Not At All
Irregular pump behavior indicates blocked weeping tile or overwhelming pressure.
Persistent Dampness or Humidity
Musty odors and high humidity after rainstorms or spring snowmelt.
Standing Water After Rainfall
Water accumulation in basement areas that previously stayed completely dry.
Sediment or Debris in Sump Pit
Silt washed into the sump pit signals collapsing or disintegrating clay weeping tiles.
Signs Your Sump Pump Needs Replacement
A failing sump pump puts your basement at risk. Common signs include:
- Frequent cycling or running continuously
- Unusual noise or vibration
- Visible rust or corrosion
- Pump not keeping up during heavy rain
- Age beyond its expected service life
- No water discharge despite the pump running
Battery Backup Systems
Power outages often happen during storms - exactly when your sump pump is needed most. Battery backup systems and secondary pumps keep water moving when the primary pump loses power or fails. High-water alarms alert you before water reaches the basement floor.
Interior vs Exterior Weeping Tile
Interior weeping tile is installed inside the foundation perimeter and connects to the sump pit. Exterior weeping tile runs outside the footing and is renewed during exterior waterproofing. We assess which system is present and whether repair or replacement is appropriate.
Installation Process
Assess Existing System
Inspect current sump, pit, and discharge line condition before recommending any work.
Inspect Weeping Tile
Check weeping tile condition where accessible to determine if repair or replacement is needed.
Recommend Solution
Provide clear repair or replacement recommendation based on inspection findings.
Install Pit & Pump
Install or replace the sump pit and pump unit with proper positioning and sealing.
Connect Discharge
Install check valve and route discharge line away from the foundation safely.
Add Backup & Alarm
Install backup pump system and high-water alarm for protection during outages.
Test & Verify
Full system test to confirm proper operation before completing the job.
Maintenance & Care
Regular maintenance keeps your drainage system reliable. We recommend periodic inspection of the sump pit, testing the pump, checking the discharge line, and verifying backup system operation before wet seasons.
