Know the Warning Signs

Is Your Unionville Home Sending You Water Damage Warnings?

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.

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.

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.

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.

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.

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.

Sump Pump Running Constantly

Constant sump cycling means your drainage system is overwhelmed. This typically signals that your waterproofing perimeter needs to be upgraded, not just the pump.

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.

Cracks in the Floor Slab

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.

What We Do

Waterproofing Services We Provide in Unionville, 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.

💧

Sub-Slab Interior Drainage Installation

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 Waterproofing & Membrane Application

Exterior waterproofing is the most comprehensive solution available — 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 — not the paint-on damp-proofing that deteriorates within a few years.

🔧

Foundation Crack Injection — Polyurethane & Epoxy Systems

We inject poured-wall cracks using a port-and-backer system: surface ports are installed at 8–12 inch intervals along the crack, the surface is sealed with hydraulic cement, and two-part polyurethane or epoxy is pumped under pressure from the lowest port up — filling the crack through its full depth.

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.

🌿

Crawl Space Encapsulation & Vapor Barrier Systems

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.

Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.

⚙️

Sump Pit Construction & Dual-Pump Waterproofing 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

Basement window wells are one of the most underestimated water entry points in residential waterproofing. When the well drain becomes clogged or the well itself is sized incorrectly for your roof drainage load, water pools against the window frame and enters through the sill, the window-to-frame joint, or the block wall directly adjacent.

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

Real Customer Reviews

Hear It From Customers Who Hired Us Across Unionville, 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."

Michael R. Basement Waterproofing Client

★★★★★

"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.That kind of result speaks for itself."

Sandra T. Property Owner

★★★★★

"I bought a house in Unionville, 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.That kind of result speaks for itself."

David K. Homeowner in Unionville, 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 Unionville, 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.That kind of result speaks for itself."

James W. Homeowner

★★★★★

"As a commercial property manager overseeing several buildings in Unionville, 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.I'd recommend them to anyone dealing with the same problem."

Common Questions

Frequently Asked Questions About Waterproofing in Unionville, IN

How do I know if I need interior or exterior 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.

How long does a basement waterproofing installation take?

Crack injection: half a day to a full day. Interior perimeter drain system: 1–3 days for most residential basements.

Will basement waterproofing affect my home's resale value?

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.

Does homeowner's insurance cover basement waterproofing?

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.

How much does basement waterproofing cost in Unionville, IN?

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.

What is the difference between damp-proofing and waterproofing?

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.

Do I need to leave my home during waterproofing installation?

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.

What causes basement walls to crack?

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.

Can waterproofing be done in winter or during rainy weather?

Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.

How do I maintain my waterproofing system after installation?

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.

Is crawl space encapsulation worth it if I don't have standing water?

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.
