Interior Basement Waterproofing
Interior waterproofing manages water after it enters the structure. We install drainage systems along the basement perimeter that collect and channel water to a sump pump basin before it spreads across the floor. For properties with recurring water intrusion through walls or the floor slab, this is the most reliable long-term solution.
Interior waterproofing works best alongside a properly sized sump pump system. We install and size both together when needed so the drainage and removal systems function as a single solution rather than two independent fixes.
Exterior Basement Waterproofing
Exterior waterproofing stops water before it reaches the foundation. We excavate around the foundation perimeter, apply waterproof membrane coating to the exterior walls, install drainage board, and route water away from the structure through a correctly pitched drainage system.
This is the most comprehensive waterproofing solution available. It addresses the source of water intrusion directly rather than managing it once it is already inside. For Baltimore properties with significant hydrostatic pressure or foundations showing active deterioration, exterior waterproofing is often the right call.
Residential and Commercial Waterproofing Across Baltimore
We waterproof single-family homes, Baltimore row homes, multi-unit residential properties, and commercial buildings. Baltimore’s clay-heavy soil and aging housing stock make water intrusion a common problem across the city, and every property presents different conditions.
We scope every job based on what we find on site, not a standard package.

Crawl Space Waterproofing
An unprotected crawl space is one of the most overlooked sources of moisture damage in Baltimore homes. Water intrusion through crawl space walls and floors raises humidity levels throughout the property, accelerates wood rot, and creates conditions for mold growth that spreads well beyond the crawl space itself.
We encapsulate crawl spaces with heavy-duty vapor barrier, seal wall penetrations, and install drainage and ventilation systems where needed. The result is a dry, stable crawl space that stops moisture at the source.
Waterproofing and French Drains
For properties where groundwater volume or soil drainage is the underlying problem, a French drain system working alongside interior waterproofing is often the more complete solution. Rather than managing water after it accumulates, the French drain intercepts and redirects it before it builds pressure against the foundation.
We assess both systems together and recommend the combination that matches your property’s actual conditions.
