The Arrow Tight Waterproofing Story β Built by Waterproofing Specialists, Not Salespeople
Too many contractors in Indianapolis sell a fix before they've actually confirmed what's wrong. Arrow Tight Waterproofing built its process around the opposite order: inspect first, document what we find, and only then put a number on paper.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Indianapolis β no subcontractors, no handoffs, no one new showing up halfway through.
We keep detailed job records for every property in Indianapolis we've serviced, which means if you call back in three years with a question about your system, we can pull the exact specs of what was installed rather than starting from scratch.
IICRC-certified technicians on every job, no exceptions
licensed in IN with full liability and workers' comp coverage
Thermal imaging and calibrated moisture readings before every quote
Written, transferable warranty on all completed systems
Direct-employee crews β never subcontracted out
Warning Signs
Six Warning Signs You Shouldn't Ignore
Most foundation failures don't start as floods β they start small, and they're easy to miss until the damage compounds. Here's what our technicians look for on every inspection in Indianapolis.
01
Efflorescence on Basement Walls
White powdery buildup on a foundation wall means water has been passing through it, even if the surface looks dry today.
02
A Musty Smell That Won't Go Away
Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.
03
Cracks Along the Wall-Floor Joint
Cracking where your floor meets the foundation wall is rarely cosmetic; it's typically the first visible sign of pressure building against the wall.
04
A Sump Pump That Never Stops Running
We treat constant cycling as an early warning, not a normal condition β the pump working overtime today is the pump failing sooner than expected.
05
Bowing or Leaning Foundation Walls
Even a slight inward lean in a block wall signals lateral soil pressure building against the foundation β this needs structural evaluation, not just a sealant.
06
Rust Stains Bleeding Through Concrete
Rust streaks mean water has reached embedded rebar or metal lath and started oxidizing it β a sign moisture has penetrated deeper than the surface.
07
Peeling Paint or Soft Drywall Near the Floor
Paint and drywall absorb moisture vapor before liquid water ever becomes visible, so bubbling or soft spots near the baseboard are an early-stage signal, not a late one.
08
Cold, Damp Floors Above a Crawl Space
Floors that stay cold and slightly damp-feeling even with the heat running usually trace back to an open or failed vapor barrier beneath the house, not an HVAC problem.
Core Services
What Arrow Tight Waterproofing Handles in Indianapolis
We don't sell a single fixed package β every property in Indianapolis gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we β our emergency line in Indianapolis is answered live, 24 hours a day, with crews dispatched to stop the immediate entry point first.
We carry the equipment needed to control an active situation immediately, then scope the permanent fix once the emergency is under control.
Residential waterproofing in Indianapolis covers everything from a single crack injection to a full-perimeter drainage retrofit, scoped after a real inspection.
We size every residential system β pump horsepower, pipe diameter, gravel bed depth β to your specific property rather than a generic template.
Commercial foundations in Indianapolis carry different risk than residential ones β larger footprints, tenant liability, and often tighter access β and our crews scope and schedule around that.
Commercial jobs get the same commercial-grade materials as our residential work β nothing scaled down because the client is a business instead of a homeowner.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Indianapolis showing signs of settlement or lateral pressure.
Every structural repair is documented with before-and-after photos and moisture readings as part of your warranty file.
Failed or undersized sump pumps are one of the most common reasons a previously working system suddenly floods, and we treat pump sizing as its own diagnostic step, not an afterthought to drainage work.
We also correct discharge line routing and grading as part of any pump job, since a poorly graded discharge line often just recirculates water back toward the foundation.
Why Property Owners in Indianapolis Choose Arrow Tight Waterproofing
These aren't marketing lines β they're the specific practices that separate a repair that lasts from one that doesn't.
Upfront, Itemized Pricing
The number on your proposal is the number on your invoice β materials, labor, and scope are itemized before any work begins, with no surprise line items added mid-job.
Fast Local Dispatch
We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Indianapolis isn't driving hours to get there.
Satisfaction Backed in Writing
If something about the completed work doesn't meet the scope we agreed to, we return and correct it under the warranty terms, in writing.
Commercial-Grade Materials, Every Time
We install the same membrane specification, pipe schedule, and pump ratings on residential jobs that commercial contracts require β never a downgraded consumer-grade substitute.
Diagnosis Before Recommendation
We inspect with thermal imaging and moisture meters before quoting anything, because a scope built on a guess is a scope that often needs redoing.
