Built for Notre Dame, IN's Toughest Moisture Problems

We've spent years responding to flooded basements and seeping foundations across Notre Dame, IN. What we learned is simple: most water intrusion problems trace back to three root causes — hydrostatic pressure, improper grading, and compromised foundation walls. We fix all three, not just the symptom you can see.

We're not a general contractor who does waterproofing on the side. Every job we take — whether it's a sump system installation, a foundation crack repair, or full exterior waterproofing — is handled by specialists. No subcontracting, no handoffs, no surprises on the invoice.

  • IICRC-Certified Waterproofing Technicians
  • Commercial-grade materials on every residential job
  • Permit-ready crews with full insurance documentation
  • Transferable written warranty on all installed systems
  • No-subcontractor policy — your crew is our crew

Don't Wait — These Signs Mean Water Is Already Winning in Notre Dame

Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Notre Dame property, schedule a free inspection before the damage compounds.

1

Efflorescence on Block or Poured Walls

That white chalky residue isn't cosmetic — it's mineral salt deposited by water that has already penetrated your foundation wall.

2

Horizontal or Stair-Step Foundation Cracks

Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure — a structural emergency, not just a cosmetic issue.

3

Musty Odor After Rain Events

Mold and mildew require only 24–48 hours of elevated moisture to colonize. A musty smell after rain means your vapor barrier has failed or doesn't exist.

4

Visible Seepage at Wall-Floor Joint

Water at the wall-floor joint indicates that groundwater pressure is pushing beneath your slab. This entry point worsens with every wet season if not addressed at the source.

5

Peeling Paint or Bubbling Drywall

If interior basement paint is peeling or drywall is soft and bubbling, you have elevated relative humidity at the wall surface — a reliable sign of ongoing water vapor migration.

6

Sump Pump Running Constantly

A sump pump that cycles every few minutes — or runs non-stop — is managing a groundwater situation your current system wasn't designed for. It will burn out, and the next flood won't wait for a replacement.

7

Rust Stains on Concrete or Block

Rust streaks on foundation walls mean moisture is reaching and oxidizing the rebar or metal lath inside your block or poured concrete — water that deep is already compromising structural integrity.

8

Cracks in the Floor Slab

Hairline slab cracks that weep during wet weather indicate hydrostatic pressure building under the slab. Left alone, that pressure will widen the cracks and lift sections of the floor.

Waterproofing Services We Provide in Notre Dame, IN

Every moisture problem has a different source. We identify yours specifically before we quote anything — then we deploy the right system, not the most expensive one.

💧

Interior Drain Tile & Perimeter Channel Systems

Interior drain tile systems collect groundwater at the footing level before it enters your living space. We saw-cut the slab perimeter, excavate to the footing, install gravel-bed perforated pipe, and tie it into a sump system with battery backup — so you stay dry even during power outages.

These systems don't fight hydrostatic pressure — they redirect it.

🏗️

Exterior Foundation Coating & Drainage Board Installation

Full exterior waterproofing involves exposing your foundation to the footer depth, applying a crystalline or elastomeric waterproofing membrane, installing a geocomposite drainage mat, and placing exterior drain tile at the footing — the same specification used in new commercial construction.

We use SilkOate, UMARK, and other commercial-grade membrane systems — not the paint-on damp-proofing that deteriorates within a few years.

🔧

Structural Crack Repair: Injection & Carbon Fiber Stapling

Poured concrete foundation cracks are repaired from the interior using high-pressure polyurethane or epoxy injection — the appropriate chemistry depends on whether the crack is actively leaking or dry. Polyurethane foam expands into wet, actively leaking cracks and cures flexible, accommodating minor future movement. Epoxy injection is used in dry cracks where structural bond restoration is the goal.

Block wall repointing involves removing deteriorated mortar joints to a minimum depth of 3/4 inch and repacking with waterproof hydraulic mortar.

🌿

Crawl Space Moisture Control: Encapsulation to Full Waterproofing

We install a minimum 20-mil reinforced poly vapor barrier over the entire crawl space floor and seal it up the walls to the sill plate — then seal all vents, install a conditioned air supply or dedicated crawl space dehumidifier, and spec a sump system if groundwater is present.

For crawl spaces with active water entry, we install a perimeter drain channel at the footer line, route it to an appropriate discharge point or sump.

📞 Schedule a Crawl Space Inspection →
⚙️

Sump Pit Construction & Dual-Pump Waterproofing Systems

A sump pump is only as reliable as its installation and backup plan. We install primary pumps — typically 1/2 to 3/4 HP cast iron submersibles with a minimum 10-year rating — alongside battery-operated backup systems that activate automatically when your primary pump fails or power goes out.

Sump pump replacement is one of the most time-sensitive repairs in waterproofing — a failed pump during a heavy rain event means an immediate flood.

Basement Window Well Repair & Drainage Installation

We excavate and regrade window wells to the proper dimension, install a gravel drain bed with a perforated pipe tied into your perimeter drainage system, and apply waterproof flashing around the window frame — stopping the entry point at the source instead of managing it inside.

Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.

Hear It From Customers Who Hired Us Across Notre Dame, IN

★★★★★

"The crew showed up within 3 hours of my call at 9 PM on a Tuesday. I had water coming in through a crack in my poured wall at the floor joint — had been watching it for two seasons and finally called when it started spreading. They installed an interior drain system along two walls and a new sump pit. The work took two days. I've had three major rain events since then — completely dry. Worth every dollar.That kind of result speaks for itself."

"I've had two other companies look at my foundation crack before these guys. Both gave me vague proposals and neither one could tell me exactly why I had water or where it was coming in. Arrow Tight Waterproofing came out, brought a thermal camera, and showed me on screen exactly where the moisture was concentrated. The polyurethane injection they did on the crack has held for 18 months now with zero seepage. That's the most competent inspection I've ever gotten from a contractor.I'd recommend them to anyone dealing with the same problem."

Sandra T. Foundation Crack Repair Client in Notre Dame, IN
★★★★★

"I bought a house in Notre Dame, IN knowing it had a moisture issue in the crawl space — previous owners had put down a thin plastic sheet that was doing nothing. Arrow Tight Waterproofing encapsulated the entire crawl space with a 20-mil liner, sealed the vents, and installed a dehumidifier. Within two weeks my downstairs floors stopped feeling cold and damp and the musty smell completely disappeared. The technician walked me through every step before starting. No surprises on the invoice.I'd recommend them to anyone dealing with the same problem."

D
David K. Crawl Space Encapsulation Client
★★★★★

"We had a window well that flooded every time we got more than an inch of rain. The well was filling up and water was coming straight in through the window sill joint. The fix was a regraded well with a perforated pipe tied into our existing interior drain. The whole job took one day. The crew was professional, cleaned up completely, and the well has handled every storm since without an issue.That kind of result speaks for itself."

Lisa M. Window Well Drainage Client in Notre Dame, IN
★★★★★

"Called Arrow Tight Waterproofing after my old sump pump failed during a storm and I had 4 inches of water on my basement floor. They answered at midnight, arrived within an hour, and had a temporary pump running within 20 minutes of showing up. Once the emergency was managed, they walked me through a permanent drainage system upgrade. That was 8 months ago — I've had 6 rain events including one significant storm and the basement has stayed dry.I'd recommend them to anyone dealing with the same problem."

"As a commercial property manager overseeing several buildings in Notre Dame, IN, I've worked with a lot of waterproofing contractors. Arrow Tight Waterproofing is the first one that showed up to the initial walk with a written inspection checklist and completed it on-site before quoting. Every other contractor just eyeballed it and sent a number. Their exterior membrane on the building we had done 3 years ago is holding perfectly with zero callbacks.Highly recommend the whole crew."

What Notre Dame Homeowners Ask About Waterproofing

The distinction comes down to where the water pressure is coming from — interior drainage handles water at the cove joint and lower wall.
Crack injection: half a day to a full day. Interior perimeter drain system: 1–3 days for most residential basements.
Yes — and the mechanism is twofold. First, a documented, professionally installed waterproofing system with a transferable warranty eliminates a major disclosure item that typically requires negotiation or price reduction during a sale.
Homeowner's policies typically cover sudden water damage — burst pipes, appliance failures — but exclude gradual seepage and groundwater intrusion. That said, we document every job with moisture readings and photographs.
There's no accurate ballpark without an inspection, because waterproofing scope varies drastically. A single crack injection and a full perimeter drainage system are both "waterproofing" — but they're completely different projects.
Damp-proofing is the asphalt coating sprayed on new foundations during construction. It costs the builder very little, is not rated for hydrostatic head pressure, and typically fails within 10–20 years.
For interior work, displacement is rarely required. There will be concrete saw noise and dust during the initial saw-cut phase — we use HEPA-equipped dust containment systems — but most homeowners remain in the house throughout an interior drainage installation.
Poured concrete cracks primarily from shrinkage during initial cure, differential settlement as soil compacts beneath the footer, and thermal cycling over seasons. Concrete block cracks most commonly at mortar joints due to differential settlement or from lateral soil pressure.
Interior waterproofing work — drain tile installation, sump systems, crack injection — can be performed year-round regardless of weather.
Post-installation maintenance is simple. For interior drainage systems: test your sump pump semi-annually, inspect the discharge line for blockage annually, and keep the pit clear of debris.
Yes — and this is one of the most consistent findings in building science research. An unencapsulated crawl space with no standing water still pushes humid ground-sourced air into your living area through the stack effect: warm air rising out of the house pulls cool.
