From basement flooding to foundation seepage, Arrow Tight Waterproofing has protected properties across Taylorsville, NC with industrial-grade waterproofing systems. Call now β crews are standing by 24/7.


We've spent years responding to flooded basements and seeping foundations across Taylorsville, NC. What we learned is simple: most water intrusion problems trace back to three root causes β hydrostatic pressure, improper grading, and compromised foundation walls. We fix all three, not just the symptom you can see.
We're not a general contractor who does waterproofing on the side. Every job we take β whether it's a sump system installation, a foundation crack repair, or full exterior waterproofing β is handled by specialists. No subcontracting, no handoffs, no surprises on the invoice.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Taylorsville 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.
Horizontal cracks mean the soil outside is pushing inward against your foundation wall. This indicates active soil movement and needs evaluation immediately.
If your basement smells earthy or musty after every heavy rain, active water intrusion is feeding organic growth β likely behind the drywall or under the slab.
The cove joint β where the floor slab meets the foundation wall β is the most common water entry point in basement systems. Staining or pooling there means hydrostatic pressure is actively pushing in.
If interior basement paint is peeling or drywall is soft and bubbling, you have elevated relative humidity at the wall surface β a reliable sign of ongoing water vapor migration.
A sump pump that cycles every few minutes β or runs non-stop β 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 β 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 β so you stay dry even during power outages.
These systems don't fight hydrostatic pressure β they redirect it.
π Get a Free Drainage Quote βFull 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 β the same specification used in new commercial construction.
This approach solves the problem at the source: water never reaches your interior wall surface.
π Schedule an Exterior Assessment βWe inject poured-wall cracks using a port-and-backer system: surface ports are installed at 8β12 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 β filling the crack through its full depth.
For concrete block foundation walls showing horizontal cracking or inward bowing, we pair crack repair with carbon fiber reinforcement straps anchored at the floor and rim joist.
π Get a Crack Injection Estimate βCrawl spaces are the most overlooked moisture source in residential structures. An unencapsulated crawl space β even one that "never floods" β pumps humid air into your living area through the stack effect, raising indoor humidity, feeding mold growth in floor joists, and accelerating wood rot in your subfloor structure. Full encapsulation seals that air pathway permanently.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.
π Schedule a Crawl Space Inspection βThe 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 β a failed pump during a heavy rain event means an immediate flood.
π Get a Sump System Quote βBasement 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 β but paired with proper drainage installation.
π Book a Window Well Assessment βThere are a lot of waterproofing companies in NC. Here's what separates the ones who fix the problem from the ones who fix the symptom β 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.

π Call +1-866-476-1348 β Free Estimate"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 β 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 β completely dry. Worth every dollar.Highly recommend the whole crew."
"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 Taylorsville, NC knowing it had a moisture issue in the crawl space β 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.Highly recommend the whole crew."
"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 β I've had 6 rain events including one significant storm and the basement has stayed dry.Highly recommend the whole crew."
"As a commercial property manager overseeing several buildings in Taylorsville, 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."
