Excavation.
Built Right from the Ground Up.
Every great pavement starts below the surface. PSI's in-house excavation crew handles site preparation, subgrade work, trenching, and earthmoving — giving us full control from raw ground to finished asphalt.
Pavement is only as strong as
what's underneath it.
Whether it's a new parking lot, a residential driveway, or a municipal road, the excavation phase determines the lifespan of everything built on top. Poor subgrade preparation leads to premature cracking, settlement, and costly repairs — often within the first few years.
PSI's excavation crew works with the same precision and care as our paving and grading teams — because we know the work we do below grade directly affects the finished surface. Proper depth, drainage, and compaction at the excavation stage means fewer callbacks and a longer-lasting result.
Because excavation is handled in-house, there's no gap between digging and the next phase of your project. The same team that excavates your site also prepares the base, manages grading, and coordinates paving — keeping the project on schedule and on budget.
We build foundations that last.
From raw ground to
pave-ready surface.
PSI manages every phase of excavation in-house — from the initial site walk to final subgrade compaction. One crew, one schedule, zero gaps between trades.
Dig it once.
Dig it right.
PSI doesn't just show up with a machine. Every excavation project starts with a thorough site review — soil conditions, drainage, utility locations, and engineered plans — so the work is done correctly the first time. Rework is expensive. Getting the subgrade right from day one is the most cost-effective investment you can make in your pavement.
From residential driveways to large-scale commercial parking lots and municipal road projects, PSI's excavation crew has the equipment, experience, and local knowledge to handle any scope across the BC Interior.

Frequently Asked Questions
Common questions about excavation and site preparation in the BC Interior.
PSI provides excavation for parking lots, roads, residential driveways, site preparation, land clearing, and utility trenching. We handle everything from small driveway digs to large commercial and municipal projects across the BC Interior.
Asphalt pavement is only as strong as the base and subgrade beneath it. Improper excavation depth, poor drainage, or inadequate compaction leads to premature cracking, rutting, and settlement — often requiring costly repairs within the first few years. Getting the excavation right is the single most important investment in long-term pavement performance.
Yes. Hauling, stockpiling, disposal, and import of new materials are all part of the scope. PSI coordinates trucking alongside excavation so there are no delays waiting on third-party haulers.
Absolutely — that's one of the biggest advantages of working with PSI. We handle excavation, base preparation, and asphalt paving with one team. There's no gap between trades, no miscommunication, and one point of accountability from start to finish.
Typical commercial parking lot excavation ranges from 300–500mm below finished grade, depending on soil conditions, traffic loads, and the required base thickness. PSI determines the correct depth during the site assessment and confirms it against the engineered design.
If subgrade soils are weak, saturated, or unstable, PSI can coordinate soil stabilization, geotextile fabric installation, or additional base depth to create a stable foundation. We identify these conditions during excavation and address them before paving — not after.
Yes. PSI provides precision trenching for storm drains, water lines, electrical conduit, and other underground utilities. Backfill and compaction are included in the scope to ensure the trench doesn't settle or compromise the finished surface.
Timeline depends on the size and complexity of the project. A residential driveway excavation may take a day, while a large commercial lot or road project could take one to two weeks. PSI provides a clear timeline during the quoting process and keeps you updated throughout.
PSI provides excavation services across the BC Interior, including Kamloops, Salmon Arm, Sun Peaks, Chase, Sorrento, Blind Bay, Enderby, Armstrong, Vernon, Sicamous, Revelstoke, and the North and South Shuswap.
