We install French drains across Battle, East Sussex and the wider South East to intercept, collect and redirect surface water away from properties, fields, driveways and boundaries.

French drains are one of the most effective and versatile drainage solutions for the clay and chalk soils of Kent and East Sussex — they prevent waterlogging, protect foundations, stop gardens from flooding and keep driveways and access routes passable through wet winters.

French Drains FAQs

Frequently Asked Questions

What is a French drain?

A French drain is a gravel-filled trench containing a perforated pipe that intercepts and collects surface water and groundwater, directing it away from the area to a soakaway, watercourse or drainage outfall. The gravel allows water to flow freely into the pipe, while a geotextile membrane prevents silt from clogging the system. We install French drains across Battle, East Sussex, Kent and Surrey.

How deep should a French drain be?

French drains are typically installed between 300mm and 600mm deep for surface water management, and up to 900mm or deeper where groundwater interception is needed. The depth depends on the soil type, the volume of water to be managed and whether the drain is intercepting surface water or groundwater. We specify the correct depth during our free site survey.

Do French drains work in clay soil?

Yes, French drains are particularly effective in the heavy clay soils found across Kent and East Sussex. In clay ground, surface water drains slowly and tends to pool. A French drain with perforated pipe and clean gravel backfill provides a path for water to flow away, and the geotextile membrane prevents clay particles from silting up the system.

Can you install a French drain in my garden?

Yes. We install garden French drains for lawns, borders and boundaries suffering from waterlogging and surface water flooding across the South East. For restricted-access gardens, we use mini and micro excavators that can work through narrow gateways and tight spaces.

How long do French drains last?

A properly installed French drain with geotextile membrane, clean drainage stone and perforated pipe can last 25-30 years or more. The key to longevity is preventing silt ingress, which is why we wrap the pipe in geotextile and use clean, washed gravel rather than recycled material.
