Concrete base vs wet bed for driveways
Outdoor driveway paving often ends up on the more structural side of residential work: you are building a small pavement,
not a thin veneer over whatever was there before.
A well-built crushed-rock bed with compliant sand bedding can serve many residential drives when soils are stable, falls are generous and
product thickness matches wheel loads. Where reactive soils, tight levels to the garage slab or heavier use suggest otherwise, teams
specify a concrete slab with adhesive bedding to stiffen the system.
Site conditions—not internet rules of thumb—should steer the decision. The same street can present different sub-grades front-to-back.
