Driveway & Patio Drainage Planning in BC

Before pouring concrete or paving, plan slope, runoff, drains, thresholds and base preparation so water moves away from buildings.

Updated 2026-08-27 · Homeowner planning guide

Home-service decisions are easier when you know what information to collect before calling contractors. This guide focuses on practical planning and questions to ask; it is not a substitute for a site-specific professional assessment.

Start with where water should go

Every hard surface sheds water. Decide the safe drainage path before selecting concrete, asphalt or pavers.

Protect building thresholds

Garage doors, exterior doors and low foundation areas need careful elevations. A small grading mistake can direct water toward the building.

Base preparation matters

The finished surface relies on the material underneath. Ask how excavation, compaction and base thickness are handled for the site.

Plan joints and transitions

Concrete needs planned joints, and every surface needs clean transitions to sidewalks, garages and landscaping. These details should be in the layout before installation.

Think beyond appearance

Colour and finish matter, but slope, drainage and base preparation are what determine whether the new surface performs through wet seasons.
