BASEMENT DRAINAGE & WATERPROOFING
IN
OTTAWA AND SURROUNDING AREAS
Water in the basement never fixes itself. We find where it’s coming from and recommend the drainage or waterproofing solution that actually fits your home — with the same no-deposit promise Capital City is known for.
Sound Familiar?
Every wet basement has a source. These are the problems we’re asked about most — and each one points to a different solution.
Water finding its way through the foundation after rain or thaw, pooling on the floor.
Cracks in poured concrete or block walls that let water and moisture migrate inside.
Musty smells, peeling paint and humid air that slowly damage finishes and belongings.
Repeated entry points around windows, floor edges or wall penetrations that keep returning.
Our Services
The right solution depends on the source of the water problem — our assessment identifies it before we recommend anything.
A trench and perforated drain line at the base of the walls captures seepage before it reaches your floor and carries it to the sump. The go-to fix for recurring floor-edge water.
Cracks in poured foundations are often sealed from inside with injection — no digging required. We assess each crack and recommend the repair that suits it.
Where a drainage system needs a discharge point, we install reliable sump pumps and upgrade tired ones so collected water leaves your basement for good.
Not every solution suits every property. Interior drainage, crack injection, sump work and exterior waterproofing each fit different situations — the appropriate fix depends on assessing where the water enters your home.

You get a clear recommendation — interior drainage, crack repair, sump work or exterior waterproofing — matched to the source.
Winter Work
Water problems don’t wait for spring, and neither should you. Homeowners can enquire year-round about:
A note on exterior excavation: digging and exterior waterproofing depend on ground conditions and weather. Frozen ground can make excavation impractical, so we schedule that work honestly — when it can be done right.

FAQ
Usually due to foundation cracks, poor exterior drainage, heavy rain, snowmelt, or high hydrostatic pressure around your foundation walls.
Interior drainage is faster, less invasive, and cost-effective for managing incoming water.
Exterior waterproofing stops water before it ever enters the foundation but requires digging outside.
Yes, non-structural and minor cracks can often be injected and sealed with epoxy or polyurethane foam directly from the inside.
Proper waterproofing drastically reduces moisture and flooding risks, but long-term success requires regular maintenance of sump pumps, gutters, and drainage systems.
