Arrow Tight Waterproofing: Maple Plain, MN's Most Trusted Waterproofing Contractor
We've spent years responding to flooded basements and seeping foundations across Maple Plain, MN.

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 — whether it's a sump system installation, a foundation crack repair, or full exterior waterproofing — is handled by specialists. No subcontracting, no handoffs, no surprises on the invoice.

8 Signs Your Maple Plain Property Needs Waterproofing Right Now
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Maple Plain property, schedule a free inspection before the damage compounds.
1
Efflorescence on Block or Poured Walls
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.
2
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.
3
Musty Odor After Rain Events
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.
4
Visible Seepage at Wall-Floor Joint
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.
5
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.
6
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.
7
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.
8
Cracks in the Floor Slab
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.
What We Do
Waterproofing Services We Provide in Maple Plain, MN
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.
💧
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.
Exterior Foundation Waterproofing & Membrane Application
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.
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.
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.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.
Sump Pit Construction & Dual-Pump Waterproofing Systems
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.
Window Well Drainage & Egress Window Waterproofing
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 — stopping the entry point at the source instead of managing it inside.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.

What Maple Plain, MN Homeowners Say About Arrow Tight Waterproofing
★★★★★
"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.That kind of result speaks for itself."

Michael R.Homeowner in Maple Plain, MN
★★★★★
"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."
S
Sandra T.Property Owner
★★★★★
"I bought a house in Maple Plain, 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. 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."
D
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.Highly recommend the whole crew."
L
Lisa M.Window Well Drainage Client in Maple Plain, MN
★★★★★
"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."
J
James W.Homeowner
★★★★★
"As a commercial property manager overseeing several buildings in Maple Plain, MN, 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
What Maple Plain Homeowners Ask About Waterproofing
The distinction comes down to where the water pressure is coming from — interior drainage handles water at the cove joint and lower wall.
Interior drain tile systems typically take 1–2 days depending on perimeter footage; full exterior excavation runs 2–5 days depending on footer depth.
Yes — and the mechanism is twofold. First, a documented, professionally installed waterproofing system with a transferable warranty eliminates a major disclosure item that typically requires negotiation or price reduction during a sale.
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.
Waterproofing costs vary significantly based on the solution required, the perimeter footage, and the existing drainage conditions. Interior drain tile systems for a standard residential basement typically run $4,000–$12,000.
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.
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.
Poured concrete cracks primarily from shrinkage during initial cure, differential settlement as soil compacts beneath the footer, and thermal cycling over seasons. Concrete block cracks most commonly at mortar joints due to differential settlement or from lateral soil pressure.
Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.
A properly installed interior drainage system and sump pump system requires minimal maintenance, but that minimal maintenance matters. Test your sump pump every 6 months by pouring water into the pit.
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.
