Signs a Basement Needs Waterproofing
Most basements give warnings long before a serious leak. Watch for damp patches that grow after rain, a white chalky crust on concrete or block walls, peeling paint near the floor, or a tide line on stored boxes.
Spring is often when problems show. As snow melts and the ground thaws, water collects against the foundation and finds the easiest way in. In Brockville and along the St. Lawrence River, cold winters bring repeated freezing and thawing, which puts steady pressure on foundation walls, joints and old drainage.
A musty smell matters too. It usually means moisture is lingering somewhere, and moisture left in place can lead to mould growth on drywall, framing and stored items.
What Our Waterproofing Work Covers
Basement waterproofing is a group of methods, not a single product. The right mix depends on the wall type, the water source and how the space is used.
- Interior perimeter drainage that collects water at the base of the wall and carries it to a sump pit.
- Dimpled wall membranes that let seepage run down behind them into the drainage channel.
- Sealing of pipe penetrations, tie holes and the joint where the wall meets the floor.
- Repair of individual leaking cracks through foundation crack injection.
- Sump pit and pump work through our sump pump installation service.
- Outside work, such as exterior foundation waterproofing, when digging is the better answer.
Interior or Exterior Waterproofing
Interior systems
Interior systems manage water that reaches the wall. They are usually less disruptive to landscaping, driveways and decks, and the work can go ahead in most weather. They suit many poured concrete and block foundations where the main issue is seepage at the floor joint.
Exterior systems
Exterior waterproofing stops water before it touches the wall. It involves excavation, so it takes more planning, but it addresses the outside face of the foundation directly and allows new weeping tile to be installed. We explain the tradeoffs for your home so you can choose with clear information.
How a Waterproofing Project Runs
- Assessment. We look at the walls, floor, grading, downspouts and any existing drainage, and we ask when and where water appears.
- Plan. You receive a clear description of the recommended work and the reasons behind it.
- Preparation. The work area is cleared and protected, and stored items are moved away from the walls.
- Installation. Drainage, membranes, sealing and pump work are completed in a logical order.
- Review. We walk through what was done and how to look after the system.
Helpful Habits After Waterproofing
Keep downspouts extended well away from the house and make sure soil slopes away from the foundation. Test the sump pump each spring and fall by pouring water into the pit. Run a dehumidifier during humid summer months, and keep stored items off the floor on shelving.
If water has already reached the floor, start with our wet basement repair page, which explains how we trace the source before recommending a fix.
