Arrow Tight Waterproofing: Plymouth, NC's Most Trusted Waterproofing Contractor
Arrow Tight Waterproofing was founded on one principle: a dry basement shouldn't be a luxury. Our crew of certified technicians covers Plymouth, NC 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 Plymouth
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Plymouth property, schedule a free inspection before the damage compounds.
1
Efflorescence on Block or Poured Walls
That white chalky residue isn't cosmetic — it's mineral salt deposited by water that has already penetrated your foundation 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
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.
4
Visible Seepage at Wall-Floor Joint
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 at the source.
5
Peeling Paint or Bubbling Drywall
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.
6
Sump Pump Running Constantly
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.
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
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.
What We Do
Waterproofing Services We Provide in Plymouth, NC
Arrow Tight Waterproofing doesn't sell one-size-fits-all waterproofing 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.
💧
Sub-Slab Interior Drainage Installation
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 Foundation Coating & Drainage Board Installation
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.
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, accommodating minor future movement. 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 of 3/4 inch and repacking with waterproof hydraulic mortar.
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.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.
Sump Pit Construction & Dual-Pump Waterproofing Systems
The sump pit itself matters as much as the pump. We construct 18-inch diameter pits with a gravel bed at the base for proper water collection, sealed lids to prevent vapor and radon entry, and a discharge line that terminates a minimum of 10 feet from the foundation at a positive-grade daylight point.
For finished basements and properties with high groundwater, we recommend a dual-pump system: a primary submersible at normal operating level and a pedestal backup set two inches higher.
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.

What Plymouth, NC Homeowners Say About Arrow Tight Waterproofing
★★★★★
"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.I'd recommend them to anyone dealing with the same problem."

Michael R.Basement Waterproofing Client
★★★★★
"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."

Sandra T.Foundation Crack Repair Client in Plymouth, NC
★★★★★
"I bought a house in Plymouth, NC 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."
D
David K.Homeowner in Plymouth, NC
★★★★★
"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.I'd recommend them to anyone dealing with the same problem."

Lisa M.Homeowner
★★★★★
"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."

James W.Homeowner
★★★★★
"As a commercial property manager overseeing several buildings in Plymouth, NC, 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.Highly recommend the whole crew."

Common Questions
What Plymouth Homeowners Ask About Waterproofing
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.
A professionally waterproofed basement with a transferable warranty is a selling feature, not just a repair. It eliminates a mandatory disclosure item, removes a negotiation point for buyers, and makes finished basement space more credibly usable in appraisals.
Standard homeowner's insurance policies generally exclude damage from groundwater seepage, which is classified as a "maintenance issue." Sudden and accidental water damage from a burst pipe or equipment failure is typically covered.
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 a coating — typically an asphalt-based spray applied to the exterior of a new foundation during construction. It slows vapor transmission but is not designed to withstand hydrostatic pressure; it cracks, deteriorates, and fails over time.
For interior work, displacement is rarely required. There will be concrete saw noise and dust during the initial saw-cut phase — we use HEPA-equipped dust containment systems — but most homeowners remain in the house throughout an interior drainage installation.
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 waterproofing work — drain tile installation, sump systems, crack injection — can be performed year-round regardless of weather.
A properly installed interior drainage system and sump pump system requires minimal maintenance, but that minimal maintenance matters. Test your sump pump every 6 months by pouring water into the pit.
Yes — and this is one of the most consistent findings in building science research. An unencapsulated crawl space with no standing water still pushes humid ground-sourced air into your living area through the stack effect: warm air rising out of the house pulls cool.
