Drainage & French Drains in Marlton, NJ
Evesham Township, Burlington County. Family-owned, licensed and insured, and self-performing every stage of the work since 1979.
We fix soggy yards and basement seepage across Marlton and Evesham Township with French drains, regrading, downspout lines and dry wells where the soil allows. Evesham's sandy ground is crossed by dense silt layers that trap water a foot or two down, and the land is nearly flat. We find the layer, build the pitch and carry water to a proper outlet.

Sand that drains — until it doesn't
Marlton sits on the western edge of the Pinelands transition. Soils shift from silty loam near the Cherry Hill line to sandier ground moving east, and sand has a reputation for draining well. Through much of Evesham, though, dense silt lenses run under that sand and perch water a foot or two below the surface. The lawn looks fine on top and stays saturated underneath for days after a summer storm.
That pattern changes how we build a drain. The trench has to reach the perched layer, not just skim the topsoil, or it collects nothing.
High water near the lakes and ponds
Around Marlton Lakes and the low ground near the Kings Grant ponds, the seasonal high water table comes up close enough that basements take seepage along the footing. A drainage plan there has to accept that the ground itself is wet for part of the year. We focus on keeping surface and roof water away from the foundation and on intercepting water before it reaches the wall, and we're honest about what drainage can and can't do against a high water table.
What we see in each part of town
Evesham grew in waves, and drainage problems differ by area:
- 1970s and 80s subdivisions off Greentree and Elmwood Roads: settled grades, downspouts aimed at the foundation, driveways heaving from tree roots
- Kings Grant and Marlton Lakes: wooded parcels, homes expanded from seasonal cottages, long shallow utility runs and wetter ground
- Newer infill off Route 73: lots built on correctly placed fill, where calls are usually about pools, patios and runoff from neighboring land
French drains built for perched water
Our French drains are fabric-lined trenches of clean stone carrying perforated pipe at a continuous fall. In Evesham's sand, the filter fabric is essential — without it, fine sand migrates into the stone and the drain clogs within a few seasons. Because the land is close to flat, pitch has to be built, not found, so we set the pipe with a laser along the whole run.
Dry wells: sometimes yes, sometimes no
In the sandier eastern parts of the township, a dry well sized to the soil can absorb roof water and drain runoff well. Where a silt lens sits under the sand, or near the lakes where the water table is high, a dry well simply fills up. We check the ground before recommending one. If it won't work, we route water to daylight at a lower point or another outlet the township allows — never onto a neighbor's lot.
Roof water and grading come first
Downspouts emptying beside the foundation are the most common cause of basement seepage we see in Marlton. Carrying roof water away in buried solid pipe and regrading so the soil falls away from the house solves a large share of problems on its own. We compact new fill in lifts so the grade holds.
Working on wooded lots
Kings Grant and Marlton Lakes properties are often heavily wooded. We route trenches around trunks and main roots where the outlet allows, hand-dig through root zones where it doesn't, and protect the access path. Mature trees take up a lot of water, and damaging their roots can make drainage worse over time.
When water is already in the basement
If the basement is taking ground water, the outside fixes above come first. If what's coming up is sewage, the problem is the sewer line, and that's an urgent call.

When we're done, the trench is backfilled in compacted lifts, topsoil is graded to the new fall, and the lawn is ready for seed or sod. Downspout lines end at a clean outlet, dry wells are capped below grade, and concrete we cut is restored. The real test is the next summer storm: the yard should firm up within hours rather than staying soft for days. If it doesn't perform as described, we come back and look at it with you.
Utilities and restoration
The Evesham MUA provides water and sewer to most of the township. We have utilities marked and locate private lines before digging — especially important where runs are long and shallow. When a drainage line crosses a driveway or walk, we self-perform the concrete restoration; driveways heaved by tree roots can be rebuilt on a proper base at the same time.
Marlton questions, answered.
Dense silt layers under the sand trap water a foot or two down. A drain has to reach that layer to collect it.
It can reduce it a lot by keeping roof and surface water away from the foundation. Where the water table itself rises seasonally, we'll explain the limits honestly.
In the sandier eastern areas, often. Over a silt lens or near the lakes, usually not. We test before recommending one.
We route around trunks and main roots and hand-dig in root zones. Mature trees help with drainage, so we work to protect them.
