Tired of standing water, wet basements, and foundation problems?
Excavating New Jersey provides complete yard drainage and stormwater management in New Jersey—from French drains to seepage pits—protecting New Jersey homes from foundation damage, basement flooding, and standing water. We handle engineering, installation, and compliance so your property stays dry year-round.
Northern New Jersey clay soils, high water tables, and heavy rainfall create serious drainage challenges. If you are dealing with any of these issues, your property needs a professionally engineered drainage system:
· Water pooling against your foundation after every storm
· Basement moisture, musty odors, or visible seepage through walls
· Downspouts dumping thousands of gallons within feet of your house
· Negative grading that sends water toward your foundation instead of away
We diagnose the root cause—soil type, slope, hydraulic load—and install the right system the first time.

Complete drainage solutions for New Jersey properties
Our licensed team designs and installs custom drainage systems based on your property soil conditions, topography, and stormwater requirements. Every system is engineered to handle New Jersey 25-year storm events and built to last decades.
French Drain Installation & Repair
We install subsurface French drains 18-36 inches deep to intercept groundwater before it reaches your foundation. Proper installation includes geotextile fabric, clean crushed stone, and rigid PVC pipe—not the corrugated junk that fails in five years. Best for properties with high water tables, hillside runoff, or basement wall seepage.
Seepage Pit & Dry Well Construction
Our seepage pits provide underground storage and gradual percolation for roof runoff and French drain discharge. We conduct perc testing first to confirm your soil can handle infiltration—clay soils require different solutions than sandy loam. Sized correctly (3-6 feet diameter depending on hydraulic load), these systems meet NJ groundwater recharge requirements.
Liter Drain & Downspout Extensions
Your roof sheds 600-1,000 gallons per inch of rainfall. If your downspouts terminate within 5 feet of your foundation, you are creating the problem. We install underground liter drains that carry roof runoff 10-20 feet away, discharging to daylight or seepage pits. Installed below the 42-48 inch frost line so they will not freeze and back up.
Foundation Drainage & Waterproofing
Hydrostatic pressure from saturated soil forces water through foundation cracks and joints. Our exterior drainage systems combine French drains positioned 3-8 feet from foundation walls with proper discharge points. For severe cases, we integrate sump pump systems to lift water above high water tables.
Excavation & Grading Services
Negative grading is the most common drainage problem we see—and the most preventable. We re-establish positive slope (minimum 1-2 percent grade) using laser levels and transit equipment. Proper grading moves water away from structures before it becomes a subsurface problem.
Surface Swales & Catch Basins
For properties with space, vegetated swales convey surface water across yards without erosion. We design gentle side slopes (3:1 ratio) and install catch basins at driveways and low points. These manage sheet flow and protect paved surfaces from undermining.

Why excavating New jersey is the trusted drainage contractor
Serving Northern NJ Since 2006
We have solved drainage problems in Wantage, Vernon, Sparta, Hopatcong, Newton, Andover, and throughout Sussex County for nearly 20 years. We know the local soil conditions, water tables, and municipal requirements that determine which systems work and which fail.
Engineering-Based Solutions, Not Guesswork
We start every project with diagnostic assessment: perc testing to measure soil absorption rates, topographic surveys to identify drainage pathways, and hydraulic load calculations based on your roof size and impervious surfaces. Our systems are sized to handle New Jersey actual storm events—not installed based on visual observation.
The Right Materials, Installed Right
We use rigid PVC Schedule 40 pipe, non-woven geotextile fabric, and clean crushed stone. Our French drains include inspection ports every 50-75 feet for future camera inspection and maintenance. Systems installed correctly function for 25-40 years.
Compliance with N.J.A.C. 7:8 Stormwater Regulations
Many drainage projects trigger permit requirements if they alter existing drainage patterns or connect to municipal storm sewers. We handle engineering plans, municipal review, and compliance so you do not face retroactive correction orders.
Transparent Pricing & Free Site Evaluations
We provide free flat-rate estimates after evaluating your property. No surprise charges. Upfront pricing on every component—trenching, materials, discharge points, and grading work.
