Westchester County, NY · Our Services
Correcting yard slopes so surface water flows away from your foundation — not toward it. Proper grading is the first line of defense against basement moisture and one of the most cost-effective drainage improvements available.
Improper grading is one of the most common — and most overlooked — causes of basement moisture problems in Westchester County. When the ground slopes toward your foundation rather than away from it, every rainfall event directs surface water directly against your basement walls. Over time, this saturates the soil adjacent to the foundation, increases hydrostatic pressure, and forces water through even small cracks and porous concrete.
Correcting the grade around your home — establishing a positive slope of at least 6 inches over the first 10 feet from the foundation — can dramatically reduce basement moisture without any interior work. For many Westchester homeowners, grading correction is the first step we recommend before evaluating whether additional waterproofing systems are needed.
Land grading is also a standard component of exterior waterproofing projects, where backfill after excavation must be properly graded to prevent water from pooling against the newly waterproofed wall.
What this service includes:
Directs surface water away from the foundation and toward proper drainage outlets
Eliminates low spots that collect standing water after rainfall
Reduces hydrostatic pressure against basement and crawl space walls
Prevents soil erosion on sloped Westchester County properties
Improves yard usability and protects landscaping investments
Often required as part of exterior waterproofing and French drain projects
Site Survey & Drainage Analysis
We survey your property's existing grades, identify low spots and problem drainage patterns, and determine the target slope needed to direct water away from the foundation.
Excavation & Material Removal
Excess soil is excavated from high areas and removed or redistributed to fill low spots, establishing the foundation for the corrected grade.
Grading & Compaction
Fill material is placed and compacted in lifts to achieve the target grade. We establish a minimum 6-inch drop over the first 10 feet from the foundation — the standard for positive drainage away from the structure.
Drainage Integration
Where grading alone cannot resolve drainage issues, we integrate French drains, swales, or catch basins into the graded surface to handle concentrated runoff.
Seeding or Sod Installation
Disturbed areas are seeded or sodded to stabilize the new grade and prevent erosion while the soil settles and vegetation establishes.
