The Arrow Tight Waterproofing Story β Built by Waterproofing Specialists, Not Salespeople
We started Arrow Tight Waterproofing after years of watching homeowners get sold vague 'waterproofing packages' that never named the actual problem. Every technician we send in Urbana is licensed, background-checked, and trained to diagnose before quoting β not the other way around.
We've built our reputation in Urbana on jobs that don't need a second visit. That means slower quoting sometimes, since we're inspecting properly instead of estimating from a driveway conversation, but it also means fewer callbacks.
Every technician completes ongoing training as materials and methods evolve β the polyurethane injection resin we use today isn't the same formulation the industry relied on ten years ago, and neither is our crew's training.
IICRC-certified technicians on every job, no exceptions
licensed in IL 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 Urbana.
01
Efflorescence on Basement Walls
That chalky white residue on concrete or block isn't dirt β it's mineral salt left behind after water has already migrated through the wall.
02
A Musty Smell That Won't Go Away
If a dehumidifier only masks the smell instead of fixing it, there's an active moisture source somewhere in the structure.
03
Cracks Along the Wall-Floor Joint
The cove joint is the single most common water entry point in basements β staining or gaps there usually mean hydrostatic pressure is pushing water in.
04
A Sump Pump That Never Stops Running
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
05
Bowing or Leaning Foundation Walls
Measuring wall deflection with a level is one of the first things we do on any inspection where bowing is suspected, since the degree of lean changes the recommended fix.
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
If the bottom foot of drywall in a below-grade room feels soft or the paint is bubbling, that's usually vapor transmission through the wall, not a plumbing leak.
08
Cold, Damp Floors Above a Crawl Space
Homeowners often replace or service their HVAC system first, only to find the actual cause was ground moisture migrating up through an unsealed crawl space.
Core Services
Our Core Waterproofing Services in Urbana
We don't sell a single fixed package β every property in Urbana gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
When water is actively entering a property in Urbana, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
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 Urbana 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.
For property managers in Urbana, we coordinate around occupied units and business hours, minimizing disruption while still delivering a full waterproofing scope.
We provide the same written, itemized proposals for commercial clients as residential ones, with the added documentation many property managers need for ownership or insurance records.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Urbana showing signs of settlement or lateral pressure.
We're upfront when a problem needs structural engineering input beyond what waterproofing alone can fix, rather than selling a repair that won't hold.
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.
Battery backup and monitored alarm options are available on every pump we install, so a power outage during a storm doesn't leave the system unprotected.
Why Property Owners in Urbana 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
We quote a fixed price after a real inspection, not a phone estimate, and we get written sign-off before any change to that scope.
Fast Local Dispatch
Crews are staged regionally in Urbana specifically to keep response times short β most inspections are scheduled within days, and emergencies get same-day priority.
Satisfaction Backed in Writing
Every completed system comes with a written, transferable warranty β not a verbal promise that's hard to enforce two years later.
Commercial-Grade Materials, Every Time
Material selection isn't where we compete on price β we'd rather lose a bid than install something we know will fail in a few years.
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.
Our Process
How a Waterproofing Job Works With Us
01
Call or Request an Inspection
Call +1-866-476-1348 and describe the issue. We route the right technician for your specific situation rather than a generalist.
02
On-Site Diagnosis
We document every visible entry point and pressure indicator during the visit β this is what the eventual proposal is built around.
03
Written, Fixed-Price Proposal
Review the proposal at your own pace; we don't pressure same-visit sign-off, though we can often start within days once approved.
04
Installation & Warranty Documentation
We also walk you through basic maintenance for whatever was installed, so you know what to check twice a year to keep the system performing as designed.

"Had a cove joint leak that two other companies just patched without explaining why it kept happening. Arrow Tight Waterproofing's technician showed me the moisture readings and traced it to hydrostatic pressure, then installed drain tile that's held through every storm since.That's the kind of fix that actually holds up."

"We manage a small multi-unit building and needed the work scheduled around tenants. They coordinated everything cleanly and the commercial-grade membrane they used has zero callbacks two years later.That's the kind of fix that actually holds up."

"Appreciated that they didn't just sell us a package. The inspection actually found the real problem β a bowing block wall β and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.Exactly the level of service we expected."

"Sump pump had been cycling nonstop for weeks before we called. They correctly diagnosed it as undersized for our actual water table and upgraded it β no more constant cycling, and it's kept up with two heavy storms since.Would recommend them without hesitation."

FAQ
Waterproofing Frequently Asked Questions
Standard inspections are typically scheduled within a few days of your call; active emergencies get same-day priority dispatch in most of our coverage area.
Yes β every job gets a written, itemized proposal after a real on-site inspection, and that number is what you're invoiced, not an estimate that grows once work starts.
Our emergency line is answered live 24/7, and crews carry equipment for immediate water extraction, temporary sump deployment, and active crack sealing on the first visit.
If interior fixes haven't held or the wall shows active exterior deterioration, exterior waterproofing is usually the better long-term answer β we'll tell you honestly which applies.
Gradual groundwater seepage is typically treated as a maintenance issue and excluded, while sudden events like burst pipes are often covered β check your specific policy language.
Crack injection is usually a few hours; interior drain tile runs 1 to 3 days depending on perimeter footage; full exterior excavation can run 2 to 5 days depending on depth.
Always an in-person inspection β we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Yes β every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
Coverage extends across Urbana β call +1-866-476-1348 to confirm your specific address, though it's almost certainly within our service area.
For the actual repair, it depends on scope β interior work often doesn't require you to be present for the full job, while we'll coordinate access details with you directly for anything involving excavation.
A patch treats the visible symptom β a caulked crack, a coat of sealant β without addressing why water found that path in the first place, so the same issue often resurfaces nearby.
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.
Service Area
Waterproofing Coverage in Urbana
We built our coverage in Urbana around regional crew staging rather than one central office, which keeps dispatch times shorter across the footprint we serve.
Call +1-866-476-1348 to confirm coverage for your specific address β given our regional staging in Urbana, it's very likely within our service area.
Whether your property in Urbana has a finished basement, an unfinished crawl space, or a slab foundation, our crews carry the equipment and training to assess and quote all three foundation types on the same visit.
New service areas are added as we expand our regional crew staging, so if you were told we didn't cover your address in the past, it's worth checking again.
