The Waterproofing Team Moline, MI Calls When It Matters

We've spent years responding to flooded basements and seeping foundations across Moline, MI. 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

Is Your Moline Home Sending You Water Damage Warnings?

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

1

Efflorescence on Block or Poured Walls

White powder on concrete means water has been migrating through your wall. The mineral deposits are left behind when water evaporates after passing through the block or poured wall.

2

Horizontal or Stair-Step Foundation Cracks

Horizontal cracks mean the soil outside is pushing inward against your foundation wall. This indicates active soil movement and needs evaluation immediately.

3

Musty Odor After Rain Events

If your basement smells earthy or musty after every heavy rain, active water intrusion is feeding organic growth — likely behind the drywall or under the slab.

4

Visible Seepage at Wall-Floor Joint

The cove joint — where the floor slab meets the foundation wall — is the most common water entry point in basement systems. Staining or pooling there means hydrostatic pressure is actively pushing in.

5

Peeling Paint or Bubbling Drywall

Paint and drywall absorb moisture vapor before you can see liquid water. Bubbling or peeling in a below-grade space is almost always a moisture problem, not a paint adhesion failure.

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

Iron in your concrete doesn't rust unless water penetration has reached it. Rust staining is a reliable indicator that your foundation waterproofing envelope has been breached.

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 Moline, MI

Arrow Tight Waterproofing doesn't sell one-size-fits-all waterproofing packages. We diagnose the entry point, the pressure source, and the existing drainage condition — then we build the solution around what your specific property needs.

💧

Interior French Drain & Perimeter Drainage 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.

Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

🏗️

Full Excavation Exterior Waterproofing Systems

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.

For concrete block foundation walls showing horizontal cracking or inward bowing, we pair crack repair with carbon fiber reinforcement straps anchored at the floor and rim joist.

🌿

Full Crawl Space Waterproofing & Drainage Installation

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 Pump Installation, Replacement & Battery Backup Systems

The sump pit itself matters as much as the pump. We construct 18-inch diameter pits with a gravel bed at the base for proper water collection, sealed lids to prevent vapor and radon entry, and a discharge line that terminates a minimum of 10 feet from the foundation at a positive-grade daylight point.

For finished basements and properties with high groundwater, we recommend a dual-pump system: a primary submersible at normal operating level and a pedestal backup set two inches higher.

Egress Window Waterproofing & Well Cover Systems

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.

Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.

Hear It From Customers Who Hired Us Across Moline, MI

★★★★★

"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.Highly recommend the whole crew."

Michael R. Homeowner in Moline, MI
★★★★★

"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."

S
Sandra T. Foundation Crack Repair Client in Moline, MI
★★★★★

"I bought a house in Moline, MI 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.Highly recommend the whole crew."

L
Lisa M. Window Well Drainage Client in Moline, MI
★★★★★

"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.Highly recommend the whole crew."

J
James W. Emergency Waterproofing Client in Moline, MI
★★★★★

"As a commercial property manager overseeing several buildings in Moline, MI, 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.That kind of result speaks for itself."

What Moline 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.
A professionally waterproofed basement with a transferable warranty is a selling feature, not just a repair. It eliminates a mandatory disclosure item, removes a negotiation point for buyers, and makes finished basement space more credibly usable in appraisals.
Standard homeowner's insurance policies generally exclude damage from groundwater seepage, which is classified as a "maintenance issue." Sudden and accidental water damage from a burst pipe or equipment failure is typically covered.
Waterproofing costs vary significantly based on the solution required, the perimeter footage, and the existing drainage conditions. Interior drain tile systems for a standard residential basement typically run $4,000–$12,000.
Damp-proofing is a coating — typically an asphalt-based spray applied to the exterior of a new foundation during construction. It slows vapor transmission but is not designed to withstand hydrostatic pressure; it cracks, deteriorates, and fails over time.
You generally don't need to leave. Interior drainage work involves concrete cutting (noisy for a portion of the first day) and we use dust barriers and HEPA vacuums at the saw.
Foundation wall cracks typically result from two forces: differential settlement (one part of the foundation moving more than another as soil consolidates beneath it) and hydrostatic pressure (water-saturated soil exerting lateral pressure against the wall).
Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.
A properly installed interior drainage system and sump pump system requires minimal maintenance, but that minimal maintenance matters. Test your sump pump every 6 months by pouring water into the pit.
A dirt floor crawl space — even one with no visible water — maintains near-100% relative humidity at the ground surface, and that moisture migrates upward by diffusion and stack effect air movement. You don't need standing water to have a moisture problem in a crawl space.
