Should I reinforce a Vancouver paver driveway under an RV pad?

Yes, absolutely reinforce a paver driveway that will support an RV. Standard residential driveways are designed for passenger vehicles (4,000-6,000 lbs), but RVs typically weigh 10,000-40,000+ lbs with concentrated axle loads that will destroy a standard paver installation within months.

RV pad reinforcement requires significantly deeper base preparation and commercial-grade pavers. Instead of the standard 10-12 inch base for regular driveways, an RV pad needs 18-24 inches of compacted granular base in controlled lifts. The pavers themselves must be upgraded to 80mm commercial-grade units rated for heavy vehicular traffic, or better yet, 100mm pavers designed specifically for truck and RV applications. These thicker pavers distribute the concentrated axle loads over a larger area and resist cracking under point loads.

Metro Vancouver's clay-heavy soils make proper subgrade preparation even more critical for RV pads. Clay soil in Surrey, Richmond, Delta, and Langley becomes unstable when saturated, and the heavy RV loads will punch through inadequate base preparation into the clay subgrade. Geotextile fabric between the clay and the gravel base is mandatory to prevent clay migration. Consider a geogrid reinforcement layer mid-depth in the base for additional load distribution — this is standard practice for commercial parking lots and truck loading areas.

Drainage design becomes critical with RV weight and Vancouver's 1,200mm+ annual rainfall. The deep excavation required for the thicker base must include perforated drain pipe at the base of the excavation, surrounded by clear drain rock, with positive drainage to daylight or the storm drain. Standing water beneath an RV pad will saturate the base and cause catastrophic settling under the concentrated loads. Surface drainage is equally important — RVs create large impervious areas that shed significant runoff during Vancouver's heavy winter rains.

Expect to invest $35-$60 per square foot for a properly engineered RV pad — significantly more than standard driveway paving. A typical RV pad (400-600 sq ft) runs $14,000-$36,000 installed with proper base depth, commercial pavers, drainage, and reinforcement. This is not a DIY project — the excavation depth, precise compaction requirements, and load calculations require professional equipment and experience.

Consider concrete as an alternative for dedicated RV parking. A 6-8 inch reinforced concrete pad with proper vapor barrier and control joints may be more cost-effective than heavy-duty pavers for a dedicated RV parking area. However, if you want the aesthetic appeal of pavers and the ability to replace individual units if damaged, properly engineered paver installation will handle RV loads reliably.
