Built for Lancaster, SC's Toughest Moisture Problems

Arrow Tight Waterproofing was built by tradespeople who got tired of seeing homeowners in Lancaster, SC get sold band-aid fixes. We specialize in permanent waterproofing solutions β€” interior drainage systems, exterior membrane applications, crack injection, and crawl space encapsulation β€” using commercial-grade materials that hold up decade after decade.

Our process starts with a thermal imaging inspection and a moisture meter reading at multiple wall and floor elevations. That data drives the scope β€” we don't guess, and we don't sell you a $10,000 system when a $1,200 crack injection solves the problem.

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

Is Your Lancaster 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 Lancaster 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

Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure β€” a structural emergency, not just a cosmetic issue.

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

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.

5

Peeling Paint or Bubbling Drywall

If interior basement paint is peeling or drywall is soft and bubbling, you have elevated relative humidity at the wall surface β€” a reliable sign of ongoing water vapor migration.

6

Sump Pump Running Constantly

A sump pump that cycles every few minutes β€” or runs non-stop β€” 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 β€” water that deep is already compromising structural integrity.

8

Cracks in the Floor Slab

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.

Waterproofing Services We Provide in Lancaster, SC

Every moisture problem has a different source. We identify yours specifically before we quote anything β€” then we deploy the right system, not the most expensive one.

πŸ’§

Interior Drain Tile & Perimeter Channel Systems

When hydrostatic pressure is the primary culprit, the most effective long-term solution is a properly engineered interior drainage system. We install sub-slab perforated drain tile around the perimeter of your basement β€” capturing water before it can rise above slab level β€” and route it to a sump pit equipped with a dual-pump configuration.

Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

Full Excavation Exterior Waterproofing Systems

Exterior waterproofing is the most comprehensive solution available β€” stopping water before it contacts your foundation wall. 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 to redirect surface water away from the structure.

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

πŸ”§

Structural Crack Repair: Injection & Carbon Fiber Stapling

Poured concrete foundation cracks are repaired from the interior using high-pressure polyurethane or epoxy injection β€” the appropriate chemistry depends on whether the crack is actively leaking or dry. Polyurethane foam expands into wet, actively leaking cracks and cures flexible, accommodating minor future movement. Epoxy injection is used in dry cracks where structural bond restoration is the goal.

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

Crawl spaces are the most overlooked moisture source in residential structures. An unencapsulated crawl space β€” even one that "never floods" β€” 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. Full encapsulation seals that air pathway permanently.

Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.

Primary & Backup Sump Pump Systems for Lancaster 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.

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.

Basement Window Well Repair & Drainage Installation

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 β€” stopping the entry point at the source instead of managing it inside.

Window well covers are a maintenance measure, not a waterproofing solution β€” but paired with proper drainage installation.

What Lancaster, SC Homeowners Say About Arrow Tight Waterproofing

β˜…β˜…β˜…β˜…β˜…

"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 β€” 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 β€” 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 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 Lancaster, SC knowing it had a moisture issue in the crawl space β€” 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."

β˜…β˜…β˜…β˜…β˜…

"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."

"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 β€” I've had 6 rain events including one significant storm and the basement has stayed dry.Highly recommend the whole crew."

"As a commercial property manager overseeing several buildings in Lancaster, SC, 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."

Frequently Asked Questions About Waterproofing in Lancaster, SC

The distinction comes down to where the water pressure is coming from β€” 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.
A professionally waterproofed basement with a transferable warranty is a selling feature, not just a repair. It eliminates a mandatory disclosure item, removes a negotiation point for buyers, and makes finished basement space more credibly usable in appraisals.
Homeowner's policies typically cover sudden water damage β€” burst pipes, appliance failures β€” but exclude gradual seepage and groundwater intrusion. That said, we document every job with moisture readings and photographs.
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 β€” 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.
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.
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).
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 β€” 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.
