What's Included
Coastal BC gets a lot of rain, and water that sits against a foundation or under a driveway causes most of the damage we see. We excavate, install and grade so water has somewhere to go.
- Perimeter drains for new foundations: perforated pipe, filter fabric and drain rock around the footing
- Perimeter drain replacement on existing homes with failed, crushed or root-blocked drains
- Connections to approved discharge points such as a ditch, rock pit or storm connection
- Culvert installation under driveways and access roads
- Ditching and swales to carry surface water
- Yard and lot grading so the ground slopes away from buildings
- Drainage around septic fields and building pads
We quote after a site visit. Depth to footing, access around the house, soil, and where the water can discharge all affect the price.
Our Process
- Site visit. We look at where water collects, how the house and lot are graded, and where water can discharge
- Written quote. A clear scope and quote with no surprise line items
- Locates. BC 1 Call locates so buried services are marked before we dig
- Excavate and install. Trench to footing depth, install pipe, fabric and drain rock, connect to discharge
- Backfill and grade. Backfill, compact and grade away from the building, then clean up
Permits and Rules to Know
- Building permits: Perimeter drains on a new build are part of your building permit and inspection with the City of Campbell River or Strathcona Regional District.
- Culverts at the road: A culvert in a provincial road ditch is covered by your MoTT access permit. See driveway construction.
- Streams and wetlands: Work near watercourses may need provincial approval. Ask us early.
- BC 1 Call before digging: Before any excavation we request a locate through BC 1 Call so buried hydro, gas, telecom and water lines are marked. The service is free and is the expected first step before any ground disturbance.
Service Areas
Based in Campbell River and Quadra Island, we serve all surrounding areas and regularly barge equipment to Cortes Island, Read Island, Sonora Island, West and East Thurlow Island, and the other Discovery Islands. We also take on work in the Comox Valley. If your property is boat- or barge-access only, ask us. Our fleet is sized and rigged for barge transport.
Why Jagged Mountain
Jagged Mountain Excavating is family-run, with four generations of earthworks experience and more than 15 years operating on Vancouver Island and the Discovery Islands. We are BC Safe Certified, carry certified blasting operators for rock that a machine can't move, and serve 10+ islands with a barge-ready fleet. We also build ponds and water management systems, so we understand how water moves across a whole property, not just along one wall.
Frequently Asked Questions
How do I know my perimeter drain has failed?
Common signs are water in the basement or crawlspace, damp walls, or water pooling against the foundation. Have the system inspected before you excavate.
How much does perimeter drain replacement cost?
It depends on depth, access, soil and discharge point. We quote after a site visit. Call 778-785-7333 or request a quote.
Do you install culverts?
Yes. We install culverts under driveways and access roads, along with ditching and water control.
Can you fix a wet yard or driveway?
Yes. Grading, swales, ditching and culverts can carry surface water away from where it causes problems.
Do you work on the Discovery Islands?
Yes. We are based in Campbell River and Quadra Island and regularly barge equipment to Cortes, Read, Sonora, the Thurlow Islands and other islands.
