What We Do

Comprehensive Basement Waterproofing Solutions in Somerville, NJ

Every Somerville, NJ Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Basement

Interior Drain Tile

The core fix for most Somerville, NJ basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

FAQ

Basement Waterproofing Questions We Hear Every Week

How much does interior drain tile installation cost?▼

Every Somerville, NJ quote is itemized in writing so you can see exactly what drives the total.

Will you cut into my basement floor?▼

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.
