7 Engineered Systems. One Mission.
Every Shield system is designed by civil engineers for DMV soil, water table, and foundation conditions. No off-the-shelf solutions. No subcontractors. Lifetime warranty.
Why Shield?
Because Your Foundation Deserves an Engineered Defense, Not a Product Pitch.
Most waterproofing companies sell you a product: a brand-name pump, a generic membrane, a one-size encapsulation kit. We do not. We are civil engineers who design integrated defense systems for your home’s specific soil, water table, and foundation type.
The Shield Series is our family of seven systems. Each one is engineered to address a specific failure mode in DMV homes. Each one is installed by our own crews, never a subcontractor. Each one is backed by a warranty that travels with the home, not the homeowner.
- Engineered for DMV clay, marine clay, saprolite, and schist soils
- Installed by W-2 employees with engineering oversight on every job
- Lifetime transferable warranty on structural systems
- No franchise fees, no acquisition history, no script-reading sales reps
The Engineering Difference
We diagnose first, then prescribe. A FootingShield™ install is not right for every home, and neither is a WallShield™. The right system depends on soil drainage, foundation age, water table depth, and grade. Our free engineering inspection identifies which Shield, or combination, actually solves your problem.

The Three Foundations of the Shield Series
FootingShield™
Interior drain tile at footing depth, installed up to 16 inches below the slab. Reinforced concrete restoration. Engineered for clay soil and high water tables.
- DepthUp to 16″
- Best ForInterior leaks
- WarrantyLifetime
- Install Time1-2 days
WallShield™
2-layer engineered membrane on the outside of the foundation wall. Installed once. Designed to last. The hardest way to waterproof, done right.
- MethodExcavation
- Best ForPermanent fix
- WarrantyLifetime
- Install Time3-5 days
CrackShield™
Polyurethane pressure injection on concrete walls. We waterproof the crack, then repair it. Most companies do the opposite. 25-year warranty.
- MethodPressure injection
- Best ForSingle cracks
- Warranty25 years
- Install TimeSame day

Four More Shields for Complete Home Protection
Sometimes the water never reaches the foundation because we stop it at the grade, the crawl space, the yard, or the air itself.
GradingShield™
Re-graded perimeter and engineered surface flow that pushes water away from the foundation before it enters.
Perimeter DrainageMoldShield™
Certified remediation that removes existing mold and engineers the conditions to prevent it from coming back.
Mold RemovalCrawlShield™
Full crawl space encapsulation with vapor barrier, dehumidification, and engineered insulation for DMV humidity.
Crawl SpaceYardShield™
French drains, dry wells, and subgrade drainage that handle the water your downspouts and grading miss.
Yard DrainageWhy DMV Is Different
Four Soils. Four Failure Modes. One Engineered Response.
The DMV region sits on four distinct soil types, and each one fails differently under hydrostatic pressure. A FootingShield™ install for Loudoun clay is not the same as one for Kensington schist. We engineer for the soil under your home.
Triassic Clay
High plasticity. Seasonal swell and shrink. Hydrostatic pressure on foundations climbs after every freeze-thaw cycle.
Saprolite + High Water Table
Decomposed bedrock with poor drainage and shallow water table. Interior drainage solutions are often required.
Marine Clay
Bull Run basin clay. Holds water like a bowl. Foundations need engineered exterior drainage, not just sump pumps.
Wissahickon Schist
Historic homes on schist substrate. Foundation age and soil type demand careful CrackShield™ and WallShield™ integration.
Decision Guide
Which Shield Is Right for Your Home?
| If You Are Seeing | Likely Cause | Engineered Solution | Why It Works |
|---|---|---|---|
| Wet floor at wall-floor joint | Hydrostatic pressure under slab | FootingShield™ | Captures water at footing level, before it reaches the slab. |
| Water seeping through wall | Failed exterior membrane or grading | WallShield™ + GradingShield™ | Replaces the broken first line of defense, then redirects surface water. |
| Single vertical crack | Concrete shrinkage or settlement | CrackShield™ | Pressure injection waterproofs, then closes the crack. |
| Musty smell · humid air | Crawl space vapor or hidden mold | CrawlShield™ + MoldShield™ | Encapsulation stops the moisture, remediation removes what already grew. |
| Pooling water in yard | Poor grading or subsurface flow | GradingShield™ + YardShield™ | Surface and subsurface drainage push water away before it threatens the home. |
