Water doesn't wait for business hours, and neither do we. Arrow Tight Waterproofing brings licensed Sump Pump Installation expertise to properties throughout Oregon, OR with same-day dispatch and upfront flat-rate pricing.


We've spent years responding to flooded basements and seeping foundations throughout Oregon, OR. What we've 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.
We're not a general contractor who does waterproofing on the side. Every job we take in Oregon, OR — whether it's a sump system installation, a foundation crack repair, or a full exterior waterproofing scope — 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 Oregon, OR property, schedule a free inspection before the damage compounds.
That white chalky residue isn't cosmetic — it's mineral salt deposited by water that has already penetrated your foundation wall.
Horizontal cracks mean the soil outside is pushing inward against your foundation wall. This indicates active soil movement and warrants evaluation immediately.
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.
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.
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.
Constant sump cycling means your drainage system is overwhelmed. This typically signals that your waterproofing perimeter needs an upgrade, not just the pump.
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 — typically requiring sub-slab drainage and sump installation to relieve the pressure permanently.
Arrow Tight Waterproofing doesn't sell one-size-fits-all 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, anywhere in Oregon, OR.
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.
These systems redirect hydrostatic pressure along an engineered path straight to your sump pit and out of your property through a properly graded discharge line.

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.
This approach solves the problem at the source: water never reaches your interior wall surface.
📞 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, 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 →Crawl spaces are the most overlooked moisture source in residential structures. An unencapsulated crawl space — even one that never floods — 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.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.
📞 Schedule a Crawl Space Inspection →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.
📞 Get a Sump System Quote →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.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.

📞 Call Now: +1-866-476-1348"The crew showed up within 3 hours of my call at 9 PM. 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. 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 where the water 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 has held for 18 months with zero seepage.That kind of result speaks for itself."
"I bought a house in Oregon, OR 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.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 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 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. 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 property manager overseeing several buildings in Oregon, OR, I've worked with a lot of waterproofing contractors. Arrow Tight Waterproofing is the first that showed up to the initial walk with a written inspection checklist and completed it on-site before quoting. Their exterior membrane on the building we had done 3 years ago is holding perfectly with zero callbacks.I'd recommend them to anyone dealing with the same problem."
