How much does a concrete garage pad cost compared to an asphalt pad in NB?

A concrete garage pad in New Brunswick typically costs $8-$12 per square foot installed, while an asphalt pad runs $4-$7 per square foot — making concrete roughly 50-75% more expensive upfront but significantly more durable in NB's harsh freeze-thaw climate.

For a standard two-car garage pad (24x24 feet, 576 square feet), you're looking at $4,600-$6,900 for concrete versus $2,300-$4,000 for asphalt. However, these cost differences tell only part of the story when you consider New Brunswick's climate realities and long-term performance.

Concrete performs dramatically better in NB's freeze-thaw cycles. Our winters regularly swing from -20°C to above freezing, sometimes multiple times per week during shoulder seasons. This constant expansion and contraction destroys asphalt within 8-12 years in most NB locations, while a properly installed concrete pad lasts 25-40 years. Concrete also handles the weight of modern trucks and SUVs without rutting or deformation, which is increasingly important as vehicles get heavier.

Asphalt's lower upfront cost comes with significant maintenance requirements in our Maritime climate. You'll need to seal-coat every 2-3 years ($300-$600 per application), repair cracks annually, and expect complete replacement within a decade. Factor in these ongoing costs, and concrete becomes the more economical choice over 15+ years. Asphalt also becomes soft and sticky during NB's hot summer days, tracking into the house and garage.

For garage construction specifically, concrete offers crucial advantages. Most garage door systems work better on concrete — the solid, level surface prevents door binding and track misalignment that's common with settling asphalt. If you're planning an attached garage, concrete integrates seamlessly with the foundation system and provides the stable base needed for proper door operation year-round.

Preparation costs are similar for both materials — excavation, grading, and granular base typically run $2-$4 per square foot regardless of surface choice. The difference lies in the surface material and installation. Concrete requires forming, reinforcement (wire mesh or rebar), and skilled finishing, while asphalt needs compaction equipment and hot-mix delivery timing.

Consider your specific situation carefully. If you're building a simple detached garage for basic vehicle storage and plan to move within 10 years, asphalt's lower upfront cost might make sense. But for attached garages, heated garages, workshops, or long-term property ownership, concrete's durability and performance advantages typically justify the higher initial investment.

For the best of both worlds, some NB homeowners choose a concrete apron (the first 8-10 feet from the garage door) with asphalt for the remainder of the driveway. This puts concrete where door operation and heavy traffic matter most, while using asphalt for areas that see lighter use.
