GradingShield™ · DC, Maryland & Virginia
Exterior French Drain
Manage water beside your home before it becomes a basement problem.
GradingShield™ collects surface and near-surface water along the foundation perimeter and routes it to an agreed outlet.

The right repair for your home
When is a shallow drain the right fit?
Water collecting beside the house may call for shallow perimeter drainage. We check the source first: wall leaks may need exterior waterproofing, water beneath the slab may need interior drainage and a sump system, and pooling farther into the lawn may need a broader yard drainage plan.

Dry-well options depend on soil conditions, available fall, capacity and overflow. The outlet is outside these photos.
A written price for your home
What affects the cost?
After inspecting your home, we give you a written scope and price based on:
- Length & grading: the trench route, ground levels and soil.
- Access: utilities, window wells, paths and planting beds.
- Discharge: the outlet, connection length and overflow provisions.
- Restoration: the agreed surface finish and any related repairs.
Homeowner questions
Before you decide.
Can this be combined with exterior waterproofing?
If both are recommended, we coordinate the wall waterproofing, backfill and shallow perimeter drain in one installation plan.
Does the system need maintenance?
Keep accessible collection and discharge points clear and check them after storms. We explain upkeep for your installation. Review later landscaping or excavation before disturbing the drainage route.
