Diagnosis & Assessment

How do you identify the source of a basement leak?

We perform a full moisture inspection: exterior grading, foundation walls, floor-wall joint, window wells, and drain/sump performance, then provide photos and a written report.

Do you use moisture meters or thermal imaging?

Yes—non-invasive meters and thermal cameras help locate hidden moisture paths and cold joints without opening walls unless necessary.

Can you inspect during rainfall or spring melt?

Yes. Wet-weather inspections often reveal active entry points, making diagnosis faster and more accurate in Ottawa’s thaw season.

What if water appears only after heavy storms?

That suggests hydrostatic pressure or overwhelmed drainage. We recommend weeping tile checks, sump sizing, and, if needed, exterior waterproofing.

Do you test for high water table conditions?

We evaluate soil type, nearby water bodies, and sump cycle frequency to confirm groundwater influence and select the right system.

Will you open finished walls to inspect?

Only with permission and when needed. We minimize openings, document findings, and close safely or coordinate with your finisher.

Exterior Basement Waterproofing

What is exterior waterproofing?

Excavate to footing, clean the wall, repair cracks, apply primer + membrane, add drainage board, new weeping tile, and drainage stone to stop water before entry.

When is exterior better than interior waterproofing?

When walls are deteriorated, exterior cracks are visible, or you want a building-envelope fix that prevents water from touching the wall.

How deep do you excavate?

Typically to footing depth (6–8 ft on many Ottawa homes). We shore as needed, protect utilities, and follow safety standards.

Do you waterproof block (CMU) and poured concrete differently?

Yes. We address hollow cores in block walls, parge as needed, and use compatible membranes and terminations for each substrate.

Can exterior waterproofing fix foundation bowing?

It addresses water but not structural bowing. Pair with structural repairs (e.g., carbon fiber, engineer-specified bracing) if needed.

How long does exterior waterproofing last?

With proper prep and materials, 25+ years is typical. Our systems include a written, transferable warranty.

Interior Waterproofing Systems

What is an interior drainage system?

A perimeter channel at the slab edge drains to a sump. It relieves hydrostatic pressure and manages water after it enters the wall/slab joint.

Will interior waterproofing keep my basement dry?

Yes—when correctly installed with a vapor barrier and reliable sump, it keeps basements dry for finishing and storage.

Is interior waterproofing dusty or disruptive?

We use dust control, negative air where needed, and clean daily. Most jobs finish in 1–2 days for standard runs.

Can interior systems work without a sump pump?

They require a drain destination. A sump is standard; gravity drains are possible if the lot allows.

Do interior systems handle minor wall seepage?

Yes. We include wall liners/vapor barriers that direct seepage into the drain channel.

Can I finish walls after interior waterproofing?

Absolutely. We provide finishing guidelines (gap at bottom, moisture-resistant materials, insulated rim joists).

Foundation Crack Repair & Structural

Do you repair foundation cracks from inside?

Yes—polyurethane or epoxy injections seal active leaks and restore structural continuity, depending on crack type.

What’s better: epoxy or polyurethane injection?

Epoxy bonds structural cracks; polyurethane expands to stop active water leaks. We choose based on movement and moisture.

Will crack repair work on block walls?

Block cracks often need exterior membrane + drainage or interior channels; injections are limited on hollow cores.

Do you fix honeycombing and cold joints?

Yes—surface prep, injection ports, and compatible resins seal porous areas and joints.

Can you stabilize settling footings?

We coordinate with engineers for underpinning or helical/piers where settlement is confirmed.

How soon can I paint over a repaired crack?

Usually 24–72 hours after cure, depending on resin and humidity. We’ll advise on finish compatibility.

Sump Pumps & Battery Backups

Which sump pump size do I need in Ottawa?

Most homes use 1/3–1/2 HP primary pumps; high-inflow areas may need 3/4–1 HP. We size based on inflow tests.

Do I need a battery backup?

Yes. Power failures often coincide with storms. A battery backup keeps pumping and protects finished basements.

How loud are sump pumps?

Quality pumps are quiet. We add rubber isolation and proper lids to reduce noise and odors.

How often should my sump run?

Cycle rate depends on groundwater. Short frequent cycles suggest upsizing the basin, adding check valves, or optimizing discharge.

Can you install a water-powered backup?

Where code and water pressure allow, but battery backups are more common and efficient.

Do you replace old basins and check valves?

Yes—new sealed basins, airtight lids, and high-quality check valves improve reliability and reduce smells.

Drainage, Weeping Tile & Grading

What is weeping tile?

A perforated drain pipe at footing level that collects water and directs it to a sump or storm outlet.

How do I know if my weeping tile is clogged?

Basement seepage, slow sump cycling, or camera inspections revealing sediment indicate blockages.

Do you replace clay or collapsed weeping tiles?

Yes—modern PVC/HDPE with filter fabric and drainage stone prevents future clogging.

Should downspouts be extended?

Absolutely—minimum 6–10 feet away from the foundation reduces surface loading on the wall.

Can poor grading cause leaks?

Yes. Negative slope funnels water toward the foundation. We regrade to a positive slope, typically 5% for the first 6–10 feet.

Do you install exterior cleanouts?

Yes—surface cleanouts allow future flushing and maintenance without excavation.

Crawl Spaces & Encapsulation

Do you encapsulate crawl spaces?

Yes—vapor barrier, sealed seams, insulation, and drainage/sump integration to control humidity and odors.

Will encapsulation reduce mold risk?

Lower humidity reduces mold potential and protects framing and insulation.

Do you insulate crawl space walls or floors?

We follow building science best practices—often wall insulation with sealed rim joists for efficiency.

Can you add a dehumidifier to the crawl space?

Yes—sized to the volume and ducted if needed for even distribution.

How long does crawl space work take?

Most projects finish in 1–2 days depending on access and size.

Window Wells & Egress

Do window wells cause leaks?

Improper drains or clogged gravel can flood wells and push water into the basement.

Do you install or replace window well drains?

Yes—tie into weeping tile or a sump with proper filter fabric and stone.

Do you add covers to window wells?

Clear covers keep debris out and reduce water load while allowing light in.

Can you create egress windows?

Yes—where permitted. We handle excavation, well installation, drainage, and coordinate structural lintels.

Will new wells affect grading?

We regrade around wells and add swales if needed to control surface runoff.

Call us. We troubleshoot discharge, check valves, and flow; warranty issues are prioritized.

Ottawa Climate & Seasonal Prep

How does Ottawa’s freeze–thaw affect foundations?

Freeze–thaw cycles stress cracks and joints. Proper membranes, drainage, and grading reduce movement and leaks.

Should I waterproof before finishing a basement?

Yes—waterproof first to protect your investment and meet moisture management best practices.

What spring maintenance do you recommend?

Clear downspouts, verify sump operation, and check window well drains before melt and rain.

Can heavy snow loads cause leaks?

Snowmelt concentrated near walls can overwhelm drainage. Extend downspouts and maintain grading.

Do you handle ice dam-related leaks?

We address foundation water issues and coordinate with roofing partners for ice-dam solutions if needed.

Home Resale, Tenants & Renovations

Will waterproofing increase resale value?

Dry, warrantied basements are a strong selling point and reduce buyer objections.

Can I finish my basement right after waterproofing?

Yes—after cure times. We provide finisher guidelines and moisture-safe details.

Do landlords need special systems for rentals?

We recommend robust pumps, battery backups, and alarms to protect tenant spaces.

Do you provide documentation for buyers?

Yes—warranty certificates, photos, and scope summaries help with real estate transactions.

Can you coordinate with my general contractor?

Absolutely—scope integration, sequencing, and jobsite coordination are standard.

Health, Mold & Indoor Air

Does waterproofing help prevent mold?

Yes—controlling water and humidity is the first step to preventing mold growth.

Do you remove existing mold?

We focus on water control. We can refer certified remediation partners and coordinate sequencing.

Will a dehumidifier be enough?

Dehumidifiers control humidity but won’t stop liquid water. Combine with drainage/waterproofing as needed.

Can musty smells come from the sump?

Yes—sealed lids and proper venting reduce odors.

Is basement condensation a waterproofing issue?

Often it’s humidity/temperature. We diagnose whether the source is infiltration or condensation.

Materials, Standards & Options

What membranes do you use?

We use industry-proven elastomeric membranes with drainage boards, selected for Ottawa’s climate and substrate type.

Do you use dimple board?

Yes—dimpled drainage board protects the membrane and channels water to weeping tile.

What gravel and filter fabric specs do you follow?

Clean 3/4″ drainage stone with geotextile to prevent fines intrusion.

Do you offer carbon fiber reinforcement?

Yes—for minor bowing or cracking per engineer guidance.

Are your products eco-friendly?

We choose low-VOC materials where possible and dispose of soils/debris responsibly.

Discharge, Erosion & Municipal Considerations

Where does my sump discharge?

To an exterior grade location per by-law, a storm connection, or a dedicated dry well—never into sanitary systems where prohibited.

Can discharge lines freeze?

Yes—heat cables, larger diameter, proper slope, and freeze-guard fittings reduce risk.

Will discharge cause yard erosion?

We add splash pads, extensions, or buried lines with pop-ups to spread flow.

Do you separate downspouts from weeping tile?

Yes—downspout disconnection reduces system overload and is often required.

Can you install a dry well?

Yes—sized to soil percolation and municipal guidelines.
