Arrow Tight Waterproofing doesn't sell one-size-fits-all 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, anywhere in Tennessee, TN.
💧
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, capturing water before it can rise above slab level, and route it to a sump pit 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.

Exterior Foundation Waterproofing & Membrane Application
Exterior waterproofing is the most comprehensive solution available — 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.
We use commercial-grade membrane systems — not the paint-on damp-proofing that deteriorates within a few years.

Structural Crack Repair: Injection & Carbon Fiber Stapling
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.
Block wall repointing involves removing deteriorated mortar joints to a minimum depth and repacking with waterproof hydraulic mortar.

Full Crawl Space Waterproofing & Drainage Installation
Crawl spaces are the most overlooked moisture source in residential structures. An unencapsulated crawl space — even one that never floods — 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.
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.

Sump Pit Construction & Dual-Pump Waterproofing Systems
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.

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