Drainage
Drainage and Base Prep for BC Rain
Good surfaces start below grade. Learn what to check before paving, pavers, walls, patios, walkways, and concrete flatwork.
Why drainage, gravel base depth, compaction, and grading matter for asphalt, pavers, concrete, retaining walls, and exterior renovations in wet BC weather.
When this topic matters
Good surfaces start below grade. Learn what to check before paving, pavers, walls, patios, walkways, and concrete flatwork. For Seven Stones, the practical question is how surface work, building repair, access, drainage, renovation, winter service, and qualified trade-partner coordination connect before work starts.
What to review before requesting a quote
- Photos from several angles, including access routes, drainage points, slope, and problem areas.
- Measurements, material preferences, timing constraints, and whether the property is residential, strata, commercial, or building-managed.
- Related work that may need coordination, such as Drainage & Site Prep, Grading & Earthworks, Excavation, Paving Stones.
- City, strata, tenant, or building-management requirements that affect access, notices, parking, or scheduling.
How Seven Stones approaches the scope
Canadian locally owned and operated, with 15 years of construction experience in and outside Canada. The team reviews mixed scopes honestly: crew work is separated from work that requires qualified specialists or trade partners, and surrounding construction tasks are planned around the full property context.
- Drainage & Site Prep: Drainage correction, gravel base, compaction, swales, grading, and prep for asphalt, pavers, walls, concrete, and renovations.
- Grading & Earthworks: Grade correction, slope shaping, base preparation, compaction, soil movement, and access preparation.
- Excavation: Site excavation for paving, retaining walls, drainage, concrete, renovation prep, trenching, and material removal.
- Paving Stones: Interlocking paver driveways, patios, walkways, garden paths, borders, steps, and hardscape upgrades.
Local service area notes
This topic appears often in North Vancouver, West Vancouver, Port Moody, Maple Ridge and nearby Lower Mainland communities because local properties combine rain exposure, slope, strata access, aging surfaces, dense parking, and seasonal maintenance needs.
Frequently asked questions
Heavy rain and freeze-thaw cycles can expose weak base, poor compaction, and water flow problems under asphalt, pavers, concrete, and retaining walls.
Yes. Drainage and grade issues should be reviewed before new asphalt, pavers, concrete, or wall work is finished.
