Who We Are

The Waterproofing Team Denver, NC Calls When It Matters

We've spent years responding to flooded basements and seeping foundations across Denver, NC. What we learned is simple: most water intrusion problems trace back to three root causes — hydrostatic pressure, improper grading, and compromised foundation walls. We fix all three, not just the symptom you can see.

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.

✓ IICRC-Certified Waterproofing Technicians
✓ Commercial-grade materials on every residential job
✓ Permit-ready crews with full insurance documentation
✓ Transferable written warranty on all installed systems
✓ No-subcontractor policy — your crew is our crew

Know the Warning Signs

Is Your Denver Home Sending You Water Damage Warnings?

Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Denver property, schedule a free inspection before the damage compounds.

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.

Horizontal or Stair-Step Foundation Cracks

Horizontal cracks mean the soil outside is pushing inward against your foundation wall. This indicates active soil movement and needs evaluation immediately.

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.

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.

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.

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.

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.

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

Our Full Range of Waterproofing Solutions in Denver, NC

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.

💧

Sub-Slab Interior Drainage Installation

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 — so you stay dry even during power outages.

These systems don't fight hydrostatic pressure — they redirect it.

🏗️

Full Excavation Exterior Waterproofing Systems

Full exterior waterproofing involves exposing your foundation to the footer depth, applying a crystalline or elastomeric waterproofing membrane, installing a geocomposite drainage mat, and placing exterior drain tile at the footing — the same specification used in new commercial construction.

We use SilkOate, UMARK, and other commercial-grade membrane systems — not the paint-on damp-proofing that deteriorates within a few years.

🔧

Poured-Wall Crack Injection & Block Wall Repointing

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.

🌿

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 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.

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.

Window Well Drainage & Egress Window Waterproofing

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, the window-to-frame joint, or the block wall directly adjacent.

Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.

Real Customer Reviews

Arrow Tight Waterproofing Reviews — From Properties Just Like Yours

★★★★★

"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.Highly recommend the whole crew."

Michael R. Homeowner in Denver, NC

★★★★★

"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.I'd recommend them to anyone dealing with the same problem."

Sandra T. Property Owner

★★★★★

"I bought a house in Denver, 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."

David K. Crawl Space Encapsulation Client

★★★★★

"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. Window Well Drainage Client in Denver, NC

★★★★★

"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 Denver, 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.That kind of result speaks for itself."

Common Questions

Frequently Asked Questions About Waterproofing in Denver, NC

How do I know if I need interior or exterior 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.

How long does a basement waterproofing installation take?

Interior drain tile systems typically take 1–2 days depending on perimeter footage; full exterior excavation runs 2–5 days depending on footer depth.

Will basement waterproofing affect my home's resale value?

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.

Does homeowner's insurance cover basement waterproofing?

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.

How much does basement waterproofing cost in Denver, NC?

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.

What is the difference between damp-proofing and waterproofing?

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.

Do I need to leave my home during waterproofing installation?

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.

What causes basement walls to crack?

Foundation wall cracks typically result from two forces: differential settlement (one part of the foundation moving more than another as soil consolidates beneath it) and hydrostatic pressure (water-saturated soil exerting lateral pressure against the wall).

Can waterproofing be done in winter or during rainy weather?

Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.

How do I maintain my waterproofing system after installation?

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.

Is crawl space encapsulation worth it if I don't have standing water?

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.
