From emergency extraction to permanent drain tile systems, we diagnose the real problem before recommending a fix.

Arrow Tight Waterproofing has spent years earning a reputation in Indianapolis for showing up when a basement is taking on water and not leaving until it's actually fixed.
Licensing here isn't a formality — every crew member is licensed in IN and specifically trained in the below-grade water intrusion work that Waterproofing actually requires.
We run a dispatch-first model: local crews stocked with diagnostic gear and repair materials, ready to move on active water intrusion the same day it's reported.
Beyond the repair itself, we document every diagnostic finding with photos and moisture readings, so you understand exactly what was found and why a given system was recommended.
Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.
If the basement smell comes back within days of airing it out, that's moisture, not just staleness.
Chalky white streaks on your foundation wall are a visible sign that water has been passing through the concrete itself.
Doors and windows that stick or won't latch properly, especially on the lowest level.
Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.
Standing water or damp carpet after any significant rainfall.
An overworked sump pump is a warning sign in itself — it's compensating for something upstream.
Hold a level against your foundation wall — even a small deviation from plumb is worth having evaluated.
A hygrometer reading that stays above 60% no matter how much you run a dehumidifier usually points to an active intrusion source.
Unexplained rust forming on tools or ductwork is often the first physical evidence of chronically elevated humidity.
We don't push a single product — every job starts with a diagnosis, then a recommendation matched to what's actually happening at your property.
Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.
A perimeter drain tile channel installed below the slab intercepts groundwater before it can reach your floor, routing it to a properly sized sump basin and pump. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.
We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. Injection resin fills the full depth of the crack, not just the visible surface.
This is the most thorough fix available and typically carries the longest service life, though it's not always necessary depending on what the interior diagnostic finds.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Backup systems activate automatically the instant the primary loses power or falls behind.
For walls showing early bowing alongside seepage, carbon fiber straps or steel wall anchors can arrest further movement before it becomes a bigger structural concern. We explain the engineering rationale before recommending any wall reinforcement work.
Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Indianapolis.
A lot of companies claim to offer Waterproofing, but the difference shows up in how the job is actually diagnosed and executed — not in the advertising.
We understand active seepage doesn't wait for a convenient slot, so emergency calls get dispatched immediately with equipment already loaded.
Pricing is based on what our diagnostic actually finds, not a generic per-square-foot estimate pulled out of thin air.
A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.
Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.
Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.
Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.
Describe the issue — a damp wall, standing water, a musty smell — and dispatch routes the right crew with matching equipment.
A technician arrives with moisture meters, a wall camera, and a hydrostatic pressure gauge to identify the actual entry point, not just the visible symptom.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.
What homeowners in Indianapolis, IN are saying after calling us for Waterproofing.
"Had standing water after a spring storm and they had a full drain tile system installed within the week. Completely dry since."
"They showed us the actual crack on camera before recommending anything — nobody had ever bothered to look that closely before."
"Quote matched the final invoice to the dollar. No surprise line items once they opened up the wall."
"Battery backup pump they installed kept us dry through a multi-hour outage last winter. Would've flooded otherwise."
"Appreciated that they told us plainly our crack needed an engineer's eyes before injecting anything — didn't just upsell us."
"Crawl space encapsulation got rid of a musty smell we'd been dealing with for two years. Should've called sooner."
"They walked us through the moisture readings on the spot instead of just telling us to trust them. Made the whole decision easier."
"Sump pump replacement was done same-day after our old one failed during a storm. Genuinely impressed with the response time."
"We got three other quotes before calling them, and theirs was the only one that actually explained why our specific wall was leaking."
"Vapor barrier install in our crawl space was clean, fast, and the humidity reading dropped noticeably within a couple weeks."
