Water doesn't wait for business hours, and neither do we. Arrow Tight Waterproofing brings licensed Basement Waterproofing expertise to properties throughout Ohio, OH with same-day dispatch and upfront flat-rate pricing.


Arrow Tight Waterproofing was built by tradespeople who got tired of seeing homeowners across Ohio, OH sold band-aid fixes. We specialize in permanent waterproofing solutions — interior drainage systems, exterior membrane applications, crack injection, and crawl space encapsulation — using commercial-grade materials that hold up decade after decade.
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.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Ohio, OH property, schedule a free inspection before the damage compounds.
That white chalky residue isn't cosmetic — 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 warrants evaluation immediately.
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.
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.
Paint and drywall absorb moisture vapor before you can see liquid water. Bubbling or peeling in a below-grade space is almost always a moisture problem, not a paint adhesion failure.
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.
Iron in your concrete doesn't rust unless water penetration has reached it. Rust staining is a reliable indicator that your foundation waterproofing envelope has been breached.
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.
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 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.
These systems redirect hydrostatic pressure along an engineered path straight to your sump pit and out of your property through a properly graded discharge line.

This approach solves the problem at the source: water never reaches your interior wall surface.
📞 Schedule an Exterior Assessment →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, and two-part polyurethane or epoxy is pumped under pressure from the lowest port up — filling the crack through its full depth.
Block wall repointing involves removing deteriorated mortar joints to a minimum depth and repacking with waterproof hydraulic mortar.
📞 Get a Crack Injection Estimate →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, route it to a sump, and then encapsulate over the drainage system.
📞 Schedule a Crawl Space Inspection →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.
📞 Get a Sump System Quote →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 or the adjacent block wall.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.
📞 Book a Window Well Assessment →We're not going to tell you we're the cheapest or the biggest. We're going to tell you what we do differently — and why it leads to better outcomes for your property and your wallet long-term.
Every estimate begins with a physical inspection of every visible moisture entry point.
The waterproofing membrane we apply to your foundation is the same specification used on commercial buildings — a 60-mil rubber barrier.

Your technician inspects the perimeter, scans the walls with thermal imaging, measures moisture content at every crack and stain, and maps the likely water path from grade to interior. This takes 45–90 minutes and is completely free.
We present a written, itemized proposal on-site or within 24 hours of the inspection. Fixed price, fixed scope, no open-ended line items. You review it, ask questions, and authorize in writing before any work begins.
{Our crew completes the installation to the approved scope. On completion, we conduct a post-installation moisture check, walk you through the system, and provide the written warranty documents registered to your property address.|Installation is completed by our direct-employee crew. We clean up the jobsite, verify pump function and discharge routing, take post-install moisture readings, and hand you the warranty documentation before we leave.}
If you've noticed any of the warning signs above, the damage is compounding with every wet event. A free inspection costs you nothing; a delayed repair can cost thousands more.
📞 Call Now: +1-866-476-1348"The crew showed up within 3 hours of my call at 9 PM. 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. Three major rain events since then — completely dry. Worth every dollar.I'd recommend them to anyone dealing with the same problem."
"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 where the water 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 has held for 18 months with zero seepage.I'd recommend them to anyone dealing with the same problem."
"I bought a house in Ohio, OH 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.That kind of result speaks for itself."
"We had a window well that flooded every time we got more than an inch of rain. 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.I'd recommend them to anyone dealing with the same problem."
"Called Arrow Tight Waterproofing after my 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. 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."
"As a property manager overseeing several buildings in Ohio, OH, I've worked with a lot of waterproofing contractors. Arrow Tight Waterproofing is the first that showed up to the initial walk with a written inspection checklist and completed it on-site before quoting. Their exterior membrane on the building we had done 3 years ago is holding perfectly with zero callbacks.Highly recommend the whole crew."
