From basement flooding to foundation seepage, Arrow Tight Waterproofing has protected properties statewide with industrial-grade waterproofing systems. Crews are standing by 24/7 across Ohio, OH.


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.
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.
Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure — a structural emergency, not just a cosmetic issue.
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.
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.
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.
Constant sump cycling means your drainage system is overwhelmed. This typically signals that your waterproofing perimeter needs an upgrade, not just the pump.
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.
Arrow Tight Waterproofing doesn't sell one-size-fits-all packages. We diagnose the entry point, the pressure source, and the existing drainage condition — then we build the solution around what your specific property needs, anywhere in Ohio, OH.
When hydrostatic pressure is the primary culprit, the most effective long-term solution is a properly engineered interior drainage system. We install sub-slab perforated drain tile around the perimeter, capturing water before it can rise above slab level, and route it to a sump pit with a dual-pump configuration.
Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

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.
We use commercial-grade membrane systems — not the paint-on damp-proofing that deteriorates within a few years.
📞 Schedule an Exterior Assessment →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. Epoxy injection is used in dry cracks where structural bond restoration is the goal.
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.
Sump pump replacement is one of the most time-sensitive repairs in waterproofing — a failed pump during a heavy rain event means an immediate flood.
📞 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.
Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.
📞 Book a Window Well Assessment →There are waterproofing companies throughout Ohio, OH. Here's what separates the ones who fix the problem from the ones who fix the symptom — and why Arrow Tight Waterproofing consistently lands on the right side of that line.
Our process starts with a thermal imaging scan and moisture meter readings at the wall surface, floor, and any visible crack or staining.
The waterproofing membrane we apply to your foundation is the same specification used on commercial buildings — a 60-mil rubber barrier.

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.That kind of result speaks for itself."
"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.Highly recommend the whole crew."
"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.I'd recommend them to anyone dealing with the same problem."
"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.That kind of result speaks for itself."
"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.Highly recommend the whole crew."
"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.That kind of result speaks for itself."
