Drainage & Trenching in Ladysmith

We dig trenches, lay perimeter drains, install French drains and set culverts to keep water moving away from your foundation in the Cowichan Valley.

Ladysmith Excavating installs perimeter drains, French drains, culverts and utility trenches across Ladysmith, Saltair, Chemainus and Cedar. We dig every trench to proper slope and lay drain rock so water moves cleanly away from your building. We always run BC 1 Call locates before we dig and make sure your water has a clear outfall.

What drainage and trenching includes

We install perimeter drains, French drains, swales, culverts, ditches, and utility trenches for water, power and septic lines. We dig trenches to the required depth and fall, bed and backfill them, and wrap drain lines in filter fabric and drain rock so they keep flowing.

Foundation and perimeter drainage

We lay perimeter drains around footings to divert groundwater away from your basement or crawl space. We set perforated pipe in drain rock at the base of the foundation, slope it to a positive outfall or sump, and cover it so silt does not clog it. We use perimeter drainage to protect your foundation against heavy winter rain and clay soil.

Culverts, ditching and water management

Surface water needs somewhere to go before it undermines a driveway or floods a low corner. We set driveway culverts, dig swales, and grade ditches so water runs to a clear outfall. We shape each drainage plan to the lot's slope, soil and where the water actually collects.

People also ask

Why is foundation drainage important on the Island?

The Island's heavy winter rain and clay soils push groundwater against foundations, so we run perforated pipe in drain rock along the footing to carry water away from the basement or crawlspace.

What is a French drain?

We dig gravel-filled French drains with perforated pipe to carry groundwater away from wet areas on your lot.

How deep do utility trenches need to be?

Depth depends on the service and code — water, hydro and septic lines each have minimum cover requirements, which we confirm for your specific job before trenching.

Can drainage fix a wet yard?

Often yes. Swales, French drains and culverts can redirect surface water to a safe outfall once we assess the low spots and slope on site.
