Water doesn't wait for business hours, and neither do we. Arrow Tight Waterproofing brings licensed Waterproofing expertise to North Liberty, IN with same-day dispatch and upfront flat-rate pricing.


We've spent years responding to flooded basements and seeping foundations across North Liberty, IN. What we learned is simple: most water intrusion problems trace back to three root causes β hydrostatic pressure, improper grading, and compromised foundation walls. We fix all three, not just the symptom you can see.
Our process starts with a thermal imaging inspection and a moisture meter reading at multiple wall and floor elevations. That data drives the scope β we don't guess, and we don't sell you a $10,000 system when a $1,200 crack injection solves the problem.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your North Liberty property, schedule a free inspection before the damage compounds.
That white chalky residue isn't cosmetic β it's mineral salt deposited by water that has already penetrated your foundation wall.
Horizontal cracks mean the soil outside is pushing inward against your foundation wall. This indicates active soil movement and needs evaluation immediately.
Mold and mildew require only 24β48 hours of elevated moisture to colonize. A musty smell after rain means your vapor barrier has failed or doesn't exist.
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.
If interior basement paint is peeling or drywall is soft and bubbling, you have elevated relative humidity at the wall surface β a reliable sign of ongoing water vapor migration.
A sump pump that cycles every few minutes β or runs non-stop β 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.
Rust streaks on foundation walls mean moisture is reaching and oxidizing the rebar or metal lath inside your block or poured concrete β water that deep is already compromising structural integrity.
Floor slab cracks that show moisture after heavy rain are almost always driven by sub-slab water pressure. This typically requires sub-slab drainage and sump installation to relieve the pressure permanently.
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 β then we build the solution around what your specific property needs.
When hydrostatic pressure is the primary culprit, the most effective long-term solution is a properly engineered interior drainage system. We install sub-slab perforated drain tile around the perimeter of your basement β capturing water before it can rise above slab level β and route it to a sump pit equipped with a dual-pump configuration.
These systems don't fight hydrostatic pressure β they redirect it.
π Get a Free Drainage Quote βExterior waterproofing is the most comprehensive solution available β stopping water before it contacts your foundation wall. We excavate to the footing, apply a rubberized polymer membrane to the exterior foundation face, install dimple-mat drainage board, and backfill with clean crushed stone to redirect surface water away from the structure.
We use SilkOate, UMARK, and other commercial-grade membrane systems β not the paint-on damp-proofing that deteriorates within a few years.
π Schedule an Exterior Assessment βPoured concrete foundation cracks are repaired from the interior using high-pressure polyurethane or epoxy injection β 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.
π Get a Crack Injection Estimate βWe 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 β then seal all vents, install a conditioned air supply or dedicated crawl space dehumidifier, and spec a sump system if groundwater is present.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.
π Schedule a Crawl Space Inspection βA sump pump is only as reliable as its installation and backup plan. We install primary pumps β typically 1/2 to 3/4 HP cast iron submersibles with a minimum 10-year rating β 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 β a failed pump during a heavy rain event means an immediate flood.
π Get a Sump System Quote βWe 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 β 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.
π Book a Window Well Assessment βWe're not going to tell you we're the cheapest or the biggest. We're going to tell you what we actually do differently β and why it leads to better outcomes for your property and your wallet long-term.

I had water coming in through a crack in my poured wall at the floor joint β 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 β completely dry. Worth every dollar.Highly recommend the whole crew."
"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."
"I bought a house in North Liberty, IN knowing it had a moisture issue in the crawl space β 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."
"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."
"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 β I've had 6 rain events including one significant storm and the basement has stayed dry.That kind of result speaks for itself."
"As a commercial property manager overseeing several buildings in North Liberty, 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."
