Drainage in Port Alberni
Perimeter drains, French drains and regrading to move water away from a foundation or a wet yard.
Port Alberni Excavating installs and repairs drainage across Port Alberni, Sproat Lake and Beaver Creek. On a City building permit, the final Engineering inspection checks that on-site grading complies with the regulations, and we grade to pass it.
What drainage work includes
We install and repair perimeter drains around a foundation, French drains across a yard, and we regrade the surface so water sheds away from the house instead of pooling against it.
Why grading matters
On a City building permit, a final Engineering inspection confirms that the driveway and on-site grading comply with the regulations. Poor grading is one of the most common reasons water ends up where it shouldn't.
Digging and disposal
Drainage work means trenching and hauling spoil. We check the City's Soil Removal and Deposit Regulation Bylaw No. 3947 before moving material off a Port Alberni lot, and we call BC 1 Call before we dig.
How a drainage job runs

On-site visit — we look at where water is going, and where it should go instead.

Locate and dig — we call BC 1 Call, then trench and install the drain.

Grade and backfill — we backfill, regrade the surface, and check that water moves the way it should.
What local conditions mean for this job
Drainage problems come from the site itself — the slope, the soil and what's uphill. We check the ground before we design a fix, rather than installing a standard drain everywhere.
What does a typical job look like?
- The problem
- A Beaver Creek property floods along one side of the house every fall.
- What makes it harder
- The yard grades toward the foundation instead of away from it, and there's no drain to catch the water.
- What we do
- We install a perimeter drain and regrade the yard so water runs away from the house.
People also ask
What's the difference between a French drain and a perimeter drain?
A perimeter drain runs along a foundation to keep water away from it; a French drain moves water across open ground, like a yard.
Do you need a permit for drainage work?
It depends on the scope and where the property sits. We confirm before we start.
Can bad grading cause drainage problems?
Yes — grading that slopes toward a house is one of the most common causes, and we check it as part of every drainage job.
Do you dispose of the soil from a drainage dig?
Yes, we haul it off or move it on site and price disposal separately.
