Asphalt Base Preparation in Saskatoon
The excavation, granular base, and grading that happen before any asphalt is laid, and the reason one Saskatoon driveway lasts while another fails.
Saskatoon Asphalt Co treats base preparation as the real job, because it is. The asphalt surface is what you see, but the excavation, granular base, and grading underneath are what decide whether your driveway lasts twenty years or fails in five. On our prairie ground, no amount of quality asphalt makes up for a base that was skipped.
Why the Ground Here Demands It
Saskatoon sits on heavy clay that swells when wet and shrinks when dry, and every freeze-thaw cycle through the winter moves it. A driveway laid straight onto that clay rides the movement and cracks. A driveway laid on a compacted granular base graded for drainage has a stable, well-drained foundation between the moving clay and the surface, and that is what keeps it intact through the seasons.
What We Build
We excavate to a depth suited to your ground and the traffic the driveway carries, then bring in granular material and compact it in lifts so it is dense and stable. We grade and crown the base so water sheds to the sides instead of collecting underneath, because trapped water is what freeze-thaw turns into damage. The depth, the material, and the grading are matched to your site, not pulled from a single recipe.
The Part You Cannot Redo Later
Every other service we offer can be revisited. A surface can be resurfaced, a crack sealed, a pothole cut out and refilled. The base is the exception. If it is built wrong, the only real correction is to remove the driveway and start again. That is why we spend our care here, and why a proper base is the foundation of every driveway we lay.

Driveway Base Preparation Questions
Why is base preparation so important for a driveway?
Because asphalt is only as good as what it sits on. On Saskatoon clay, a surface laid over a thin or poorly drained base has nothing stable underneath it, and freeze-thaw movement works up through it within a few winters. A properly excavated, compacted, and graded base carries the load and sheds water, and it is the single biggest factor in how long a driveway lasts.
What does proper base prep involve?
We excavate to a depth suited to your ground and how the driveway is used, then bring in granular material and compact it in place. We grade the base so it sheds water to the sides rather than holding it underneath. The depth and material depend on the site, which is why we assess your ground rather than applying one recipe to every driveway.
Can a bad base be fixed without replacing the driveway?
Usually not from the top. If the base was never built or drained properly, the fix is to remove the surface, correct the base, and repave, which is a replacement. This is exactly why the base is worth getting right the first time, since it is the part you cannot repair later without starting over.
