Should I run conduits under my Ottawa paver driveway for future use?

Absolutely yes — installing conduits under your paver driveway during construction is one of the smartest long-term investments you can make. Once the base is compacted and pavers are laid, adding electrical or other utilities requires tearing up sections of your driveway, which is expensive and disruptive.

What conduits to consider: Run 2-inch PVC electrical conduit from your house electrical panel area to key locations like the street (for future EV charging or gate operators), garage area, and any spots where you might want lighting, outlets, or security cameras. Include a separate conduit for low-voltage applications like landscape lighting, security systems, or internet cables. Many Ottawa homeowners also run a larger 4-inch conduit for future heated driveway cables — even if you're not installing the system now, having the conduit in place makes future installation dramatically cheaper.

Ottawa-specific considerations: Our deep frost line (1.2 to 1.5 metres) means conduits must be buried below the frost line to prevent heaving and damage. This is actually easier during driveway construction because you're already excavating to that depth for proper base preparation. The conduits get installed after subgrade preparation but before placing the granular base layers. Clay soils common in Ottawa (Barrhaven, Orleans, Gloucester) can shift and pinch conduits, so use continuous rigid PVC rather than flexible conduit, and ensure proper bedding with sand or fine gravel around the pipes.

Installation timing and process: Conduits must go in after excavation and subgrade preparation but before any granular base material. Mark the conduit locations clearly and take photos before covering — you'll thank yourself years later when trying to locate them. Install pull-strings or pull-tape in every conduit to make future wire installation easier. Bring conduits up through the granular base to just below the bedding sand level, then cap them securely to prevent sand infiltration during paver installation.

Cost considerations: Adding conduits during initial construction typically costs $15 to $30 per linear foot installed, depending on depth and number of conduits. Compare this to retrofitting later, which requires excavating through your finished driveway, removing and replacing pavers, and re-compacting disturbed base — easily $100+ per linear foot. For a typical Ottawa driveway, installing comprehensive conduits during construction might add $800 to $2,000 to your project cost but saves $3,000 to $8,000 if you need to add them later.

When to hire a professional: While the excavation and conduit installation can be coordinated with your paving contractor, any electrical connections must be done by an ESA-licensed electrician. Plan the conduit layout carefully — consider future EV charging needs, security lighting, gate automation, and even heated driveway systems. Many Ottawa homeowners wish they had installed more conduits rather than fewer.
