Basement Waterproofing in the Lower Mainland, BC
Stop water from entering your basement permanently. We install proven interior and exterior waterproofing systems for homes and commercial properties across Metro Vancouver — backed by a written warranty.
Your Basement Isn't Leaking by Accident
The Lower Mainland receives over 1,150mm of rain annually. Combined with clay-heavy soils that retain water and aging housing stock built without modern waterproofing, it's no surprise that basement flooding is one of the most common home problems in BC.
Water finds the path of least resistance — and that's usually your foundation. Hydrostatic pressure (the force of water-saturated soil pushing against your walls) can force water through hairline cracks, floor joints, and wall-floor connections. Over time, this causes structural damage, mold growth, and significant loss of usable space.
The solution isn't to wait and see — it's to install a permanent waterproofing system that eliminates the problem at the source.
Basement Waterproofing Solutions We Install
We don't use a one-size-fits-all approach. After assessing your basement, we recommend the right system for your specific situation.
Interior Drainage System
A perimeter drainage channel is installed along the base of your basement walls, collecting water and directing it to a sump pump. Minimally invasive, highly effective.
Exterior Waterproofing Membrane
We excavate around your foundation and apply a waterproof membrane directly to the outside wall — stopping water before it ever enters.
Sump Pump Installation
A properly sized sump pump is the heart of any interior waterproofing system. We install, replace, and service sump pumps with battery backup options.
Vapor Barrier Systems
Heavy-duty vapor barriers on walls and floors prevent moisture migration and dramatically improve basement air quality.
Window Well Drainage
Clogged or improperly installed window wells are a common source of basement flooding. We install proper drainage to keep them clear.
Crack Injection
Polyurethane or epoxy injection seals active cracks in poured concrete walls — permanently stopping water entry at the source.
