Basement Waterproofing in Severn, MD
Severn is one of Anne Arundel County's largest communities, a broad suburban area that developed through several waves from the 1960s through the 2000s. Coastal Plain soils, proximity to the Severn River watershed, and a housing stock covering 60 years of construction mean we see the full range of basement conditions here.

About Severn
Why Severn basements need local expertise.
Severn's development spans six decades, so its housing stock represents multiple construction eras: 1960s to 70s CMU block ranches and colonials, 1980s to 90s poured-concrete production homes, and 2000s to 2010s planned development. Each era has different foundation types and different drainage failure modes.
The Severn River and its tributaries define the local drainage basin. Properties near the lower-lying areas south of MD-175 are closer to the river watershed and see faster water table response after heavy rain. The higher elevations toward the BWI corridor have better natural drainage but the same Coastal Plain soil profile.
Most of our Severn work is pump upgrades and interior drainage installation on the mid-century housing, straightforward, one-day installations that give 40 to 60 year old homes a modern drainage system built to manage the pressure these foundations see.

The Ground Beneath Severn
The soil is the problem.
You can't fix what you don't understand. Maryland soil tells you everything about why your basement is wet, and what'll actually fix it.
In Severn, the soil profile under your home looks roughly like this. Hydrostatic pressure builds in the saturated zones, finds the weakest seam in your foundation, and pushes water in. The fix has to address the pressure, not just the symptom.
For Severn homeowners: the perched water table and seasonal soil saturation mean interior perimeter drainage tied to a robust sump system is the most common right answer here.

Local Context
Severn landmarks we know.
Local context shapes what we recommend. Here's what we mean.
1960s to 70s housing core (Severn proper, Arundel Village)
CMU block at 50 to 60 years, peak repair demand cohort.
MD-175 corridor
Separates higher-ground Severn from lower-lying areas closer to the river.
BWI Airport area
Higher-ground northern Severn, better drainage, more modern construction.
Severn FAQ
Questions Severn homeowners ask.
My Severn home is 50 years old and just started leaking. Why now?+
Because CMU block foundations take that long to develop the crack patterns and drainage failures that cause water. The first 20 to 30 years, the original builder drainage handles most of the load. By year 40 to 50, the block has accumulated enough freeze-thaw movement that hairline cracks have opened into active water paths, and the original sump (if any) has failed. It's predictable aging, not a structural failure.
Do you serve all of Severn or just specific areas?+
All of Severn. The community spans a large area with different drainage sub-basins, and we work throughout. We'll assess your specific location's drainage context during the inspection.
My builder installed a sump but never used it in 25 years. Should I test it?+
Immediately, because if it hasn't run in 25 years, it has likely seized. Submersible pumps need periodic operation to stay functional. Test it by dumping 5 gallons of water in the pit; if it doesn't run, replace it before the next spring event.
