I’m Alex, a drainage technician with Vancouver Underground Drainage Experts, serving Vancouver, North Van, West Van, Burnaby, Richmond, Coquitlam, Chilliwack, Surrey and the surrounding Lower Mainland. When I received a call from a busy commercial store in Burnaby about flooding at their back delivery zone, I understood immediately how serious it was. Water pooling in that area halts cleaning operations, disrupts deliveries, and creates a safety hazard. That is exactly why clients throughout Metro Vancouver rely on us for full‑scale drainage solutions.
In this blog I will guide you through each phase of the repair, from the initial camera inspection to a complete trench drain replacement, catch basin installation, and preventative maintenance advice. I will show not only how we fixed the problem, but why we are recognized as a leading water drainage company
1. Emergency Call: Back Door Flooding in Burnaby
It was early Monday morning when I arrived at the loading dock. The store manager said the area was holding several inches of water any time they rinsed the space clean.
I began with a camera inspection inside the drain channel. The footage revealed crushed concrete, packed debris, and gravel lodged deep in a channel that did not match the heavy commercial traffic load.
2. Clearing Debris and Initial Find
Next I removed the grate and manually cleared plastic wrappers, stones, and other foreign objects. I brought in a shop‑vac and a hydro pressure jet to flush the line. The system began draining water again. At that point I turned to inspect the concrete sump and saw extensive structural damage. Cracks in concrete meant the system no longer functioned safely. This was more than a clog; it was a failure that required replacement.
3. Diagnosing the Drain Failure
Here are the key reasons this channel drain failed:
- Original installation did not account for commercial trolley traffic
- It was undersized for the volume of water and debris
- Construction materials were not up to the task
- Repeated loading had caused the concrete to crack, allowing debris to enter
I explained the situation to the client in simple terms. We needed a modern trench drain replacement Burnaby system that would handle high use and harsh weather. Within minutes, the client approved full replacement.
4. Design
We designed a custom system using polymer concrete channel drain sections and reinforced steel grates. I included a new catch basin installation sized to handle peak flow.
5. Demolition and Excavation
In demo day the steps were clear:
- Remove the old, corroded grate
- Jackhammer the old channel and surrounding concrete or asphalt
- Excavate to the correct depth with consistent slope away from the building
Lay a compacted gravel bed for the new system
This step is always noisy, gritty, and messy, but necessary to set a solid foundation for the new drain.
6. Installing the New Trench Drain
The installation steps included:
- Compact the gravel base level
- Assemble polymer‑concrete channel sections with sealant between joints
- Apply rebar reinforcement for structural support
- Check trench grade toward the catch basin
- Pour concrete around the channels using vibration to avoid gaps
Install ADA‑compliant, heel‑proof grates at flush grade
I walked the client through every step, highlighting how this new design would prevent future clogging and structural issues.
7. Catch Basin Installation
We installed a high‑capacity catch basin tied into the site storm system. Debris traps prevent material from entering the municipal sewer.
8. Testing and Commissioning
After the concrete cured, I tested the system thoroughly. Using power hose water, I flushed through the entire channel. The water ran clean and free to the outlet with no sign of leaks or backup.
I reminded the client that this is how a reliable water drainage company guarantees performance.
9. Site Cleanup and Maintenance Plan
After installation I cleaned up the site thoroughly, removing all debris and wiping down surfaces. I then provided the client with maintenance advice:
- Inspect the drain system quarterly
- Schedule a catch basin cleaning service to prevent future issue
- Train staff on keeping the trenches free of trash
These steps protect the investment and keep daily operations smooth.
10. Long‑Term Results
Here is what the client achieved:
- No more water pooling at the loading dock
- Safe and efficient trolley traffic
- A trench drain system built for heavy use and harsh Metro Vancouver weather
- Ongoing support and preventative schedule for years to come
