The strength of any asphalt surface begins below the surface. At Valroc Development Ltd., we deliver precision grading and sub-base preparation services across Metro Vancouver, to ensure that every asphalt installation is built on a solid, well-compacted, and properly sloped foundation. Whether you’re paving a residential driveway, strata roadway, or commercial lot, getting the grade and base right is non-negotiable for performance, safety, and surface lifespan.
Improper grading leads to water pooling, surface cracking, and premature failure. Our experienced crew uses elevation mapping, laser levels, and compacting equipment to ensure the site is prepared to industry best practices, and to handle Canadian freeze-thaw cycles, drainage needs, and structural loads.
What Proper Grading and Sub-Base Work Achieves
Grading and sub-base preparation is a critical part of every successful asphalt project. It ensures your asphalt drains properly, stays stable under pressure, and doesn’t shift or break down over time.
– Establishes correct slope for water runoff and drainage direction
– Prevents frost heave, cracking, and settlement by stabilizing the base
– Allows for proper compaction and asphalt thickness distribution
– Supports heavy vehicle traffic without deformation or rutting
– Meets requirements for commercial, strata, or municipal site approvals
How Valroc Prepares Asphalt Sites in Metro Vancouver for Peek Performance
We approach grading and sub-base preparation with the same attention to detail as the asphalt itself. Our prep work includes site-specific planning, slope calculation, and material selection to suit the project’s scope and intended use.
– Existing surface is excavated and cleared of debris or organic matter
– Sub-base material (e.g., 3/4″ crushed gravel) added and spread evenly
– Laser levels used to ensure precise slope and proper runoff flow
– Layers are compacted using vibratory rollers for maximum density
– Final surface graded and prepared for asphalt placement
– Additional geotextile or sub-drainage included as required by site conditions
Whether you’re paving from scratch or rebuilding a failed surface, Valroc’s grading and sub-base prep ensures your asphalt doesn’t just look good, it performs under pressure and holds up over the long term.
