Basement Waterproofing
Basement waterproofing is the process of preventing water from entering your basement — protecting your foundation, your finished space, and the structural value of your home.
Our system, FootingShield™, installs drain tile up to 16″ below your slab — where water actually enters.
Every FootingShield™ includes
4″ Perforated Drain Tile
At footer depth — up to 16″ below slab
Sump + Battery Backup
Works during power outages
Slab Seat™ Preservation
Structural sections kept intact
Reinforced Concrete Restore
Rebar + epoxy + smooth finish
Lifetime Written Warranty
Transferable to next owner
The Problem
Why Water Gets Into Your Basement
Most basement leaks come from one of four causes. We diagnose which one is happening in your home — and we fix the real cause, not just the symptom.
Hydrostatic Pressure
Groundwater builds up against foundation walls and pushes water through the floor-wall joint and small cracks.
Cold Joint Leaks
The seam between footer and wall is the most common entry point. Water seeps through whenever the water table rises.
Foundation Cracks
Cracks from settling, shrinkage, or freeze-thaw cycles. We use polyurethane injection — never epoxy.
Pipe Penetrations
Old or improperly sealed pipes, conduits, and tie-rod holes create direct paths for water entry.
The Solution
FootingShield™ — Our Engineered Interior Drainage System
Not a shallow plastic gutter installed above the slab. 4" perforated drain tile at footing depth, geotextile filter fabric, washed gravel, drainboard, sump pump with battery backup. Done right, once.
Footer-Depth Drain Tile
Up to 16" below the slab — not above it. Captures water where it actually enters, before it reaches the floor.
Sump + Battery Backup
Primary pump plus battery backup that activates during power outages — exactly when storms cause flooding.
Lifetime Warranty
Written warranty for as long as your home stands. Transferable to subsequent owners. Backed by our in-house crews.

FAQ
Common Questions, Answered Straight
How long does the installation take?
Most basement waterproofing projects take 3 to 5 days depending on linear footage, basement size, and complexity. Day one is excavation, day two is drain tile and sump install, day three is slab restoration. You're home throughout — we don't displace you.
Is the lifetime warranty actually for life?
Yes. Our interior waterproofing systems carry a written lifetime warranty for as long as your home stands. It's transferable to subsequent owners and covers sump function, drain tile performance, and slab restoration.
Do I need to move out during work?
No. The work is contained to the basement perimeter. We protect floors and isolate the work area. There's some dust and noise during slab cutting (day one), but you can stay in the home throughout.
Why interior drainage instead of exterior?
Interior drainage (FootingShield™) is far less invasive than digging up your landscaping, driveway, deck, or AC units. Same lifetime protection, no exterior disruption. We do offer exterior (WallShield™) when site conditions require it.
What happens when the power goes out?
The battery backup activates automatically. Power outages and basement floods happen together — that's why every FootingShield™ install includes a battery backup at no extra charge.
Can I finance this?
Yes. We partner with Wisetack for 0% APR financing on qualifying applicants. Projects $500–$25,000. Apply in 60 seconds from your phone after your estimate. No credit impact for pre-qualification.
Do you use subcontractors?
Never. Every worker on your home — inspector, excavator, concrete finisher — is a full-time DMV Waterproofing employee. This rule has been in place since 2005 and has never been bent.
What if I just have a small leak in one corner?
We do partial installs. If the leak is isolated to a single wall or corner, we can install a partial FootingShield™ just in that zone — typically $3K–$8K range. Same lifetime warranty on the area we treat.
