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


Arrow Tight Waterproofing was founded on one principle: a dry basement shouldn't be a luxury. Our certified technicians serve every region of Minnesota, MN with industrial waterproofing systems — the same membranes, drainage matting, and injection resins used in commercial construction, installed 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.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Minnesota, MN 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 warrants evaluation immediately.
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.
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.
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.
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 — 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.
Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

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 →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, route it to a sump, and then encapsulate over the drainage system.
📞 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, sealed lids to prevent vapor and radon entry, and a discharge line that terminates 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.
📞 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.
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 →There are waterproofing companies throughout Minnesota, MN. Here's what separates the ones who fix the problem from the ones who fix the symptom — 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.
The waterproofing membrane we apply to your foundation is the same specification used on commercial buildings — a 60-mil rubber barrier.

📞 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.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 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.Highly recommend the whole crew."
"I bought a house in Minnesota, MN 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.That kind of result speaks for itself."
"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 Minnesota, MN, 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.That kind of result speaks for itself."
