Frequently Asked Questions

How often should a trench drain be replaced?

Trench drain lifespan varies based on material and usage. A well-maintained, high-quality system can last for decades, but frequent blockages or visible damage are signs that a replacement is necessary.

What are the signs of a failing trench drain?

Common signs include slow water drainage, pooling water around the drain, visible cracks or damage to the drain or surrounding concrete, and unpleasant odors from decomposing debris.

Do I need a permit for trench drain replacement in Coquitlam?

Minor repairs or like-for-like replacements on private property typically do not require a permit. However, any work that connects to the municipal storm sewer system or involves significant excavation may require a permit from the City of Coquitlam.

What is the best material for a trench drain in Coquitlam's climate?

Given Coquitlam's heavy rainfall, a durable and corrosion-resistant material like polymer concrete or stainless steel is recommended. These materials can withstand the constant moisture and temperature fluctuations common in the region.

Can I replace a trench drain myself?

While a simple drop-in replacement may be a DIY project for some, proper trench drain installation requires expertise in excavation, grading, and concrete work. For a long-lasting and effective solution, it's best to hire a professional drainage contractor.
