Built for Greenville, PA's Toughest Moisture Problems
Arrow Tight Waterproofing was founded on one principle: a dry basement shouldn't be a luxury. Our crew of certified technicians covers Greenville, PA with industrial waterproofing systems — the same membranes, drainage matting, and injection resins used in commercial construction, installed in your property at residential pricing.
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.

Don't Wait — These Signs Mean Water Is Already Winning in Greenville
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Greenville property, schedule a free inspection before the damage compounds.
1
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.
2
Horizontal or Stair-Step Foundation Cracks
Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure — a structural emergency, not just a cosmetic issue.
3
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.
4
Visible Seepage at Wall-Floor Joint
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.
5
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.
6
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.
7
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.
8
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 Greenville, PA
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 French Drain & Perimeter Drainage Systems
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 of your basement — capturing water before it can rise above slab level — and route it to a sump pit equipped with a dual-pump configuration.
These systems don't fight hydrostatic pressure — they redirect it.
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.
Block wall repointing involves removing deteriorated mortar joints to a minimum depth of 3/4 inch and repacking with waterproof hydraulic mortar.
Crawl Space Moisture Control: Encapsulation to Full Waterproofing
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 at the footer line, route it to an appropriate discharge point or sump.
Sump Pump Installation, Replacement & Battery Backup Systems
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.
We excavate and regrade window wells to the proper dimension, install a gravel drain bed with a perforated pipe tied into your perimeter drainage system, and apply waterproof flashing around the window frame — stopping the entry point at the source instead of managing it inside.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.

"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."

"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.Highly recommend the whole crew."

★★★★★
"I bought a house in Greenville, PA 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 Greenville, PA
★★★★★
"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.Highly recommend the whole crew."

"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."

"As a commercial property manager overseeing several buildings in Greenville, PA, 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.That kind of result speaks for itself."

Common Questions
Waterproofing FAQ — Answers From Arrow Tight Waterproofing Technicians
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.
Crack injection: half a day to a full day. Interior perimeter drain system: 1–3 days for most residential basements.
Yes — and the mechanism is twofold. First, a documented, professionally installed waterproofing system with a transferable warranty eliminates a major disclosure item that typically requires negotiation or price reduction during a sale.
Homeowner's policies typically cover sudden water damage — burst pipes, appliance failures — but exclude gradual seepage and groundwater intrusion. That said, we document every job with moisture readings and photographs.
There's no accurate ballpark without an inspection, because waterproofing scope varies drastically. A single crack injection and a full perimeter drainage system are both "waterproofing" — but they're completely different projects.
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.
You generally don't need to leave. Interior drainage work involves concrete cutting (noisy for a portion of the first day) and we use dust barriers and HEPA vacuums at the saw.
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.
Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.
Post-installation maintenance is simple. For interior drainage systems: test your sump pump semi-annually, inspect the discharge line for blockage annually, and keep the pit clear of debris.
A dirt floor crawl space — even one with no visible water — maintains near-100% relative humidity at the ground surface, and that moisture migrates upward by diffusion and stack effect air movement. You don't need standing water to have a moisture problem in a crawl space.
