Our Excavation Services
Site Preparation & Grading
Every construction project starts with proper site prep. We prepare your land for building by clearing, grading, and compacting soil to create a stable, level foundation.
What we do:
- Clearing and grubbing - remove vegetation, stumps, and debris
- Cut and fill grading - level uneven terrain to spec
- Soil compaction - ensure a stable base (working with geotechnical partners like Ryzuk Geotechnical for testing)
- Earthwork for foundations, slabs, footings, and post holes
- Topsoil stripping and replacement for landscaping
Whether it's a single residential lot in Cobble Hill or a multi-phase development in Duncan, we bring the right equipment and know-how to get your site build-ready on schedule. See examples of our work on our projects page.
Need materials hauled in or out? See our dump truck services.
French Drain & Drainage Installation
Water problems don't fix themselves. We design and install drainage systems that protect your property from water damage, erosion, and flooding - critical work in the Cowichan Valley's wet climate.
Drainage services include:
- French drain installation - perforated pipe systems that redirect groundwater away from foundations, basements, and low-lying areas
- Stormwater management - catch basins, swales, ditches, and culverts
- Surface drainage grading - reshaping land to direct water flow away from structures
- Foundation waterproofing trenches - excavation for waterproof membrane and drainage tile installation
- Agricultural drainage - field drainage to manage water-saturated soil
If your property in Shawnigan Lake, Mill Bay, or Cobble Hill has standing water, soggy ground, or basement moisture issues, a properly installed french drain system is often the most cost-effective long-term solution.
Land Clearing
Turning raw or overgrown land into a usable property starts with professional clearing. We handle everything from light brush clearing to full-scale tree and stump removal.
Land clearing services:
- Tree removal and felling (working with certified arborists when required)
- Stump removal - grinding or full extraction
- Brush and undergrowth clearing
- Debris removal and site cleanup
- Erosion control and slope stabilization
- Vegetation management and environmental compliance
We clear lots for new home construction, driveways, outbuildings, septic fields, and agricultural use across the Cowichan Valley.
Retaining Walls
Sloped properties, hillside lots, and eroding terrain all benefit from a well-built retaining wall. We install structural retaining walls in concrete, stone, and engineered block - with design and engineering support through our professional network.
Common retaining wall projects:
- Hillside stabilization
- Driveway and road retention
- Garden and landscape terracing
- Erosion prevention along slopes and waterways
- Structural walls for new construction on graded lots
Demolition Services
When old structures need to come down before new ones go up, we handle safe, efficient demolition and removal.
Demolition services:
- Building and structure demolition (residential and small commercial)
- Concrete removal - driveways, slabs, foundations, sidewalks
- Asphalt removal
- Interior demolition and strip-outs
- Debris hauling and disposal (or bin rental for self-loading)
All demolition work follows safety standards and regulatory requirements. We separate recyclable materials where possible.
Utility Trenching
Installing or upgrading utilities requires precise trenching to protect existing infrastructure and meet code requirements.
Trenching services:
- Water line trenching - new water service connections and replacements
- Sewer line installation and repair trenching
- Gas line trenching
- Telecommunications and electrical conduit trenching
- Irrigation system trenching
We work carefully around existing services and coordinate with utility providers as needed. Whether you're connecting a new build in Chemainus or replacing an aging water line in Lake Cowichan, we have the equipment and experience for clean, accurate trench work.
Hauling & Material Transport
Excavation generates material that needs to go somewhere - and often requires bringing in fill, gravel, or aggregate. Our dump truck services handle:
- Dirt and soil removal from excavation sites
- Gravel, sand, and crushed rock delivery
- Fill material import for grading and leveling
- Construction debris hauling
- Recycling and responsible waste disposal
