Fix Water Problems at the Source
Drainage & Grading in Southern Maryland
We design and build drainage and grading solutions that control runoff, protect structures, and restore how your property functions. From yard drainage corrections to full stormwater management, our team addresses water issues the right way, starting with the land itself.
Standing water, erosion, and runoff problems rarely fix themselves. You need a clear plan for where the water is coming from and where it should go. Our crews identify water issues and how to move it effectively to ensure your yard drains properly and stays usable after heavy rain.
When Water Stops Working Against Your Property
SERIOUS WORK, DONE RIGHT
Drainage Solutions We Build
Practical systems designed for Southern Maryland properties and soil conditions.
-
French Drain Systems
Subsurface drainage that captures and redirects water away from problem areas. Installed with proper slope, stone, and fabric so water moves efficiently underground.
-
Channel Drains
Surface-level drainage installed along patios, driveways, pool decks, or walkways. Designed to intercept water before it spreads or pools.
-
Swales & Surface Flow Control
Shallow, graded channels that guide water across the property in a controlled way. Often used for larger yards and natural drainage paths.
-
Grading & Yard Reshaping
Reworking slopes to correct standing water, runoff toward structures, and uneven areas. Proper grading is often the first step before any drainage system performs correctly.
-
Erosion Control
Solutions that stabilize soil, protect slopes, and prevent washouts during heavy rain events. Often paired with grading and drainage work for long-term results.
Built to Move Water the Right Way
Drainage is not about adding a pipe and hoping for the best. Water follows gravity, soil conditions, and pressure. That means slope, compaction, outlet locations, and sequencing all matter.
Our crews focus on the parts you do not see. Proper excavation. Correct elevations. Reliable discharge points. The result is a system that works during light rain and holds up during heavy storms.

WHAT TO EXPECT
What to Know Before Fixing Drainage Issues
-
Standing water, erosion, and soggy areas often point to slope issues. We evaluate the entire property before recommending a solution.
-
In many cases, we can add drainage to your existing patio or backyard. We assess access, elevations, and existing surfaces to determine what can be corrected without full reconstruction.
-
Some stormwater-related work requires permits, depending on scope and location. We handle permitting and approvals when required.
-
Drainage is frequently completed before patios, retaining walls, or outdoor living construction to protect the investment.
-
Smaller corrections may take a few days. Larger grading and drainage projects take longer. You receive clear scheduling and updates throughout.
