French Drains for McLean Homes
A French drain is a gravel-filled trench with a perforated pipe that collects groundwater and surface water and carries it to a safe outlet. In McLean, where basements are common and thin topsoil sits over dense clay, water often moves sideways along the clay and ends up against foundation walls or in low lawn areas. A well placed French drain intercepts that water before it causes damp basements, soggy turf or failing beds.
Local pros start by finding where the water comes from and where it can go. They study slopes, downspouts, wet spots and the path water takes during a storm. The trench is dug to the right depth and pitch, lined with filter fabric, bedded with stone and fitted with pipe that discharges to daylight, a dry well or another suitable outlet. Virginia 811 is called before digging so buried utilities are marked.
Rebuild lots in Salona Village and McLean Hamlet often have compacted fill and new grades that trap water near the house. Older homes in Kent Gardens and Chesterbrook may have downspouts that dump right at the foundation. Near stream valleys, outlets should respect protected stream buffers, so check the county map first.

Tracing surface and subsurface flow, wet spots, downspouts and slopes.

Choosing the Right French Drains Option
The main choices to talk through with your McLean pro.
Surface French drain
A shallow trench with pipe and stone handles lawn wetness at a lower cost per foot.
Curtain drain
A deeper trench uphill of the house intercepts groundwater on slopes; it costs more and protects foundations.
Decorative stone finish
A visible river rock top doubles as a dry creek look; it adds material cost but no lawn repair.
Combined with dry well
Where there is no daylight outlet, a dry well stores and releases water slowly, adding cost and needing good soil.
