Interior Crawlspace Drainage in British Columbia
Interior crawlspace drainage systems to manage groundwater and moisture in BC crawlspaces.
Professional Interior Crawlspace Drainage Across BC
Interior crawlspace drainage systems collect water that enters the crawlspace through walls or floor and direct it to a sump pit for pumping. This approach is often the most practical solution when exterior drainage is not feasible due to property constraints. Our service includes assessment of crawlspace conditions, installation of interior perimeter drains, sump pump installation with backup power, and vapour barrier installation to prevent soil moisture evaporation into the crawlspace. The combined system keeps the crawlspace dry, protects floor joists and subflooring, and prevents mould growth.
Frequently Asked Questions
Why choose interior drainage over exterior?
Interior drainage is less invasive, doesn't disturb landscaping, and is often more effective when groundwater pressure is the issue. It captures water that enters and pumps it away.
Does interior drainage include a vapour barrier?
A vapour barrier is recommended and often included, as it prevents soil moisture from evaporating into the crawlspace and condensing on the structure.
