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
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 — capturing water before it can rise above slab level — and route it to a sump pit equipped with a dual-pump configuration.
These systems don't fight hydrostatic pressure — they redirect it.

Full Excavation Exterior Waterproofing Systems
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 to redirect surface water away from the structure.
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.
For concrete block foundation walls showing horizontal cracking or inward bowing, we pair crack repair with carbon fiber reinforcement straps anchored at the floor and rim joist.

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.

Primary & Backup Sump Pump Systems for Manchester Homes
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.

Basement Window Well Repair & Drainage Installation
Basement window wells are one of the most underestimated water entry points in residential waterproofing. When the well drain becomes clogged or the well itself is sized incorrectly for your roof drainage load, water pools against the window frame and enters through the sill, the window-to-frame joint, or the block wall directly adjacent.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.
