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


Arrow Tight Waterproofing was built by tradespeople who got tired of seeing homeowners in Waterford, WI get 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.
Every technician on our team is IICRC-certified and carries full liability coverage. We pull permits where required, provide moisture readings before and after every job, and stand behind our work with a written warranty that transfers with the property.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Waterford 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.
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.
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.
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.
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 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.
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.
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.
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.

We use SilkOate, UMARK, and other commercial-grade membrane systems — not the paint-on damp-proofing that deteriorates within a few years.
📞 Schedule an Exterior Assessment →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.
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.
📞 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 at the footer line, route it to an appropriate discharge point or sump.
📞 Schedule a Crawl Space Inspection →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.
📞 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, the window-to-frame joint, or the block wall directly adjacent.
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 →We're not going to tell you we're the cheapest or the biggest. We're going to tell you what we actually do differently — and why it leads to better outcomes for your property and your wallet long-term.
Every estimate begins with a physical inspection of every visible moisture entry point.

📞 Call Now: +1-866-476-1348"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."
"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 Waterford, WI 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.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 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.I'd recommend them to anyone dealing with the same problem."
"As a commercial property manager overseeing several buildings in Waterford, WI, 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."
