Foundation Drainage Solutionsin Baltimore, MD
Water pressing against your foundation wall is the primary cause of both moisture intrusion and structural damage. Proper drainage systems relieve hydrostatic pressure and protect your foundation from the outside in.

When soil around your foundation becomes saturated — from rain, snowmelt, or a high water table — it exerts hydrostatic pressure against your foundation walls. This pressure is relentless and cumulative. Over years, it forces water through pores and cracks, and drives bowing and lateral displacement of foundation walls.
The most effective long-term protection isn't just sealing walls against water — it's removing the water from the soil before it can build up and press against the foundation. That's what foundation drainage systems do.
Our Foundation Drainage Solutions
Exterior Footing Drains
Perforated pipe buried at the foundation footing collects groundwater at the point where it would otherwise saturate the soil against the wall, routing it away from the building.
Drainage Board Installation
Dimple mat drainage board installed against the exterior foundation wall creates an air gap that channels water downward to the footing drain rather than pressing against the wall.
Window Well Drainage
Gravel-filled or piped window well drainage systems prevent wells from filling with water and pressing against basement windows and the wall surrounding them.
Downspout Extension & Grading
We assess and correct surface grading and downspout discharge to ensure water flows away from the foundation rather than pooling against it.
Interior Perimeter Drainage
Where exterior drainage is not feasible, interior perimeter drainage systems capture water that has already entered the wall assembly and route it to a sump pit.
FAQs
Does exterior drainage require excavating my yard?
Yes — exterior footing drains require excavating along the foundation wall. However, the excavation is targeted and we restore the surface after installation.
Can drainage prevent further bowing of my foundation walls?
Relieving hydrostatic pressure through drainage significantly reduces the force acting on bowing walls and is often recommended alongside stabilization repairs.
How deep are exterior footing drains installed?
Footing drains are installed at the base of the foundation footing — typically 7–9 feet below grade for a full basement in Baltimore.
What if I can't do exterior drainage?
Interior perimeter drainage systems achieve similar results by capturing water after it enters the wall assembly. We recommend the best option for your situation and budget.
