The Waterproofing Team Bunker Hill, IN Calls When It Matters
Arrow Tight Waterproofing was founded on one principle: a dry basement shouldn't be a luxury. Our crew of certified technicians covers Bunker Hill, IN with industrial waterproofing systems — the same membranes, drainage matting, and injection resins used in commercial construction, installed in your property at residential pricing.
Our process starts with a thermal imaging inspection and a moisture meter reading at multiple wall and floor elevations. That data drives the scope — we don't guess, and we don't sell you a $10,000 system when a $1,200 crack injection solves the problem.

Don't Wait — These Signs Mean Water Is Already Winning in Bunker Hill
Water damage rarely announces itself dramatically at first. It starts quiet — a damp smell, a hairline crack, a white powder on the concrete. By the time it's obvious, you've lost weeks of containment. Here's what to catch early.
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
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
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
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
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.
What We Do
Our Full Range of Waterproofing Solutions in Bunker Hill, 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.
Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.
Exterior Foundation Waterproofing & Membrane Application
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.
This approach solves the problem at the source: water never reaches your interior wall surface.
Foundation Crack Injection — Polyurethane & Epoxy Systems
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.
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.
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.
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.
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.

What Bunker Hill, IN Homeowners Say About Arrow Tight Waterproofing
★★★★★
"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."
M
Michael R.Homeowner in Bunker Hill, IN
★★★★★
"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.Property Owner
★★★★★
"I bought a house in Bunker Hill, 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.Highly recommend the whole crew."
D
David K.Homeowner in Bunker Hill, IN
★★★★★
"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 Bunker Hill, 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."
J
James W.Emergency Waterproofing Client in Bunker Hill, IN
★★★★★
"As a commercial property manager overseeing several buildings in Bunker Hill, 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."

Common Questions
What Bunker Hill Homeowners Ask About Waterproofing
Interior drainage is the right solution when your water entry is at the floor-wall joint, through the slab, or at the lower portion of the wall due to hydrostatic groundwater pressure. Exterior waterproofing is indicated when the problem originates at the exterior wall face.
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.
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.
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.
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 systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.
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.
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.
