Why GeoBrix for Waterproofing & Drains?

Water in the basement is usually more than one problem. GeoBrix walks the outside grading, the drainage, and the foundation together — then gives you a real fix, not a coat of paint.

Every job comes with a written scope, a fixed price, and a real project manager — not a runaround. We handle permits, inspections, warranties, and the clean-up.

How It Works

A simple four-step process.

Basement water is usually more than one problem. GeoBrix walks the outside grading, the drainage, and the foundation together.

01

Full Water Assessment

We walk your basement, grade, gutters, and downspouts to find the actual water source — plumbing leak, hydrostatic pressure, poor grading, or all three.

02

Written Diagnosis & Quote

You get a written scope with photos of the problem areas and a fixed price for the fix. No estimates that balloon after we start.

03

Waterproofing Install

Interior perimeter drain, sump system with battery backup, exterior grading fix, and/or crack injection — whatever the diagnosis called for.

04

Post-Install Testing

We flood-test the drain, verify the sump activation, and hand over warranty paperwork. Every waterproofing job is backed by a written warranty.

Waterproofing and Drains FAQ

Common questions.

Straight answers about what a GeoBrix Waterproofing and Drains job actually involves.

How much does basement waterproofing cost?
Interior perimeter drain systems for an average NJ basement run $5,000–$12,000. Full exterior waterproofing is $10,000–$25,000. GeoBrix quotes are fixed after we walk the space.
Do you install sump pumps?
Yes — with battery backup as standard. We install and service sumps, and can add water alarms and Wi-Fi monitoring so you know before the basement floods.
What causes a wet basement?
Usually a combination: poor grading, clogged/detached downspouts, hydrostatic pressure from high water table, foundation cracks, or plumbing leaks. GeoBrix diagnoses the actual cause before selling a fix.
Is French drain installation disruptive?
Interior French drains require breaking up the concrete perimeter — one to two feet in from the walls — and repouring after. Most jobs are done in 2–4 days.
Do you fix foundation cracks?
Yes. Structural cracks get carbon fiber straps or steel reinforcement; non-structural cracks are sealed with epoxy or polyurethane injection. Both are done in-house.
What's the warranty on waterproofing work?
GeoBrix backs waterproofing with a written warranty — typically 10 years on interior drainage systems and lifetime on structural repairs. Warranty paperwork delivered at project close.
