Who We Are

Built for Forest Lake, MN's Toughest Moisture Problems

Arrow Tight Waterproofing was founded on one principle: a dry basement shouldn't be a luxury. Our crew of certified technicians covers Forest Lake, MN with industrial waterproofing systems — the same membranes, drainage matting, and injection resins used in commercial construction, installed in your property 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.

✓ IICRC-Certified Waterproofing Technicians
✓ Commercial-grade materials on every residential job
✓ Permit-ready crews with full insurance documentation
✓ Transferable written warranty on all installed systems
✓ No-subcontractor policy — your crew is our crew

Know the Warning Signs

Is Your Forest Lake Home Sending You Water Damage Warnings?

Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Forest Lake property, schedule a free inspection before the damage compounds.

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.

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.

Musty Odor After Rain Events

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.

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.

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.

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.

Rust Stains on Concrete or Block

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.

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 Forest Lake, 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.

💧

Interior Drain Tile & Perimeter Channel Systems

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.

This approach solves the problem at the source: water never reaches your interior wall surface.

🔧

Foundation Crack Injection — Polyurethane & Epoxy Systems

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 Encapsulation & Vapor Barrier Systems

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.

⚙️

Primary & Backup Sump Pump Systems for Forest Lake Homes

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.

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.

Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.

Real Customer Reviews

What Forest Lake, 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.I'd recommend them to anyone dealing with the same problem."

Michael R. Homeowner in Forest Lake, 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."

Sandra T. Property Owner

★★★★★

"I bought a house in Forest Lake, 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.Highly recommend the whole crew."

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.I'd recommend them to anyone dealing with the same problem."

Lisa M. Homeowner

★★★★★

"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."

James W. Homeowner

★★★★★

"As a commercial property manager overseeing several buildings in Forest Lake, 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.I'd recommend them to anyone dealing with the same problem."

Common Questions

Frequently Asked Questions About Waterproofing in Forest Lake, MN

How do I know if I need interior or exterior waterproofing?

Interior drainage is the right solution when your water entry is at the floor-wall joint, through the slab, or at the lower portion of the wall due to hydrostatic groundwater pressure. Exterior waterproofing is indicated when the problem originates at the exterior wall face.

How long does a basement waterproofing installation take?

Crack injection: half a day to a full day. Interior perimeter drain system: 1–3 days for most residential basements.

Will basement waterproofing affect my home's resale value?

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.

Does homeowner's insurance cover basement waterproofing?

Homeowner's policies typically cover sudden water damage — burst pipes, appliance failures — but exclude gradual seepage and groundwater intrusion. That said, we document every job with moisture readings and photographs.

How much does basement waterproofing cost in Forest Lake, MN?

There's no accurate ballpark without an inspection, because waterproofing scope varies drastically. A single crack injection and a full perimeter drainage system are both "waterproofing" — but they're completely different projects.

What is the difference between damp-proofing and waterproofing?

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.

Do I need to leave my home during waterproofing installation?

You generally don't need to leave. Interior drainage work involves concrete cutting (noisy for a portion of the first day) and we use dust barriers and HEPA vacuums at the saw.

What causes basement walls to crack?

Foundation wall cracks typically result from two forces: differential settlement (one part of the foundation moving more than another as soil consolidates beneath it) and hydrostatic pressure (water-saturated soil exerting lateral pressure against the wall).

Can waterproofing be done in winter or during rainy weather?

Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.

How do I maintain my waterproofing system after installation?

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.

Is crawl space encapsulation worth it if I don't have standing water?

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.
