Frequently Asked Questions

How often should I have my trench drain inspected?

We recommend a professional camera inspection every 2-3 years, or sooner if you notice signs of slow drainage. This preventative measure helps catch potential issues like root intrusion or sediment buildup before they cause major blockages.

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

Yes, any work that connects to the municipal storm sewer system typically requires a permit from the Township of Langley. A professional contractor will manage this process to ensure your project is fully compliant with all local bylaws and the BC Building Code.

What is the best material for a trench drain in our climate?

For Langley's wet climate and clay soil, we often recommend polymer concrete channels for their high durability and resistance to corrosion and temperature changes. High-density polyethylene (HDPE) is also a good, cost-effective option that offers excellent flow characteristics.

Can a new trench drain be connected to my existing drainage system?

Yes, in most cases, a new trench drain can be connected to your existing perimeter drain tile or storm sewer connection. A professional assessment will determine the best connection point to ensure proper flow and system integrity.

How long does a trench drain replacement take?

A standard residential trench drain replacement typically takes 1 to 3 days to complete. The exact timeline depends on the length of the drain, the complexity of the excavation, and the type of surface restoration required.
