New Drain Installation — Drainage System Installation in East Sussex & Kent
If you need a new drainage system installed — for a new build, a development site, a waterlogged field, or a flooding property — we're the drainage contractors to call. As new drain installation contractors based in Battle, East Sussex, we design and install new drainage systems for homes, farms, estates and development sites across Kent and East Sussex. We own all our own excavators and drainage plant, so we handle the full installation from excavation through to pipe laying, connection and reinstatement.
A new drainage system is an investment that protects your property, your land, and your development. Whether you need land drainage for a waterlogged field, a French drain for a flooding garden, surface water drainage for a new driveway, or a full drainage system for a development site, we design and install drainage that works for your ground and your needs — built for the chalk, clay and sandstone soils of Kent and East Sussex.
When You Need New Drainage
Waterlogging and flooding are the most common reasons for new drainage installation. If your field floods after rain, your garden is a bog, your driveway turns into a river, or water is pooling around your property, a new drainage system is the solution. The right system — perforated pipe land drainage, French drains, soakaways, or a combination — depends on the source of the water and the ground conditions.
New builds and extensions often need new drainage installed as part of the construction. Foundation drainage, surface water drainage, foul drainage, and SuDS (Sustainable Drainage Systems) may all be required. We install drainage systems for new builds, extensions, and development sites across Kent and East Sussex, working with builders and developers to deliver drainage that meets planning and building control requirements.
Failing or inadequate drainage is another reason. If your old drains have collapsed, silted up, or are no longer coping with the water, a new drainage system may be more cost-effective than repeated repairs. We can assess your existing drainage and recommend whether to repair, upgrade, or replace.
Our New Drain Installation Services
We install perforated pipe land drainage — the backbone of field and garden drainage. Pipes are laid in gravel-filled trenches, wrapped in geotextile membrane, at the correct depth and gradient to collect and carry water to a ditch, soakaway, or watercourse. We install drainage in herringbone, grid, or single-pipe patterns depending on the site and the water problem.
We install French drains — gravel-filled trenches with perforated pipes — for surface water drainage around properties, driveways, and gardens. We also install soakaways and attenuation systems for surface water management, and surface water drainage channels for driveways and paths. For development sites, we install full drainage systems including SuDS components.
All new drain installation is carried out with our own excavators — we handle the full process from excavation through to pipe installation, gravel backfill, connection, and reinstatement. We're based in Battle, East Sussex and cover all of Kent and East Sussex. Call us on 07376 622637 for a free new drain installation quote.

Frequently Asked Questions
How much does new drain installation cost?
The cost depends on the type of drainage system, the length of drains, the depth, the ground conditions, and the outfall arrangements. Land drainage costs less per metre than French drains; full development drainage systems cost more. We provide free, no-obligation quotes after a site visit.
How deep should new drains be installed?
The depth depends on the type of drain and the ground. Land drainage is typically 600–900mm; French drains 300–900mm; surface water drainage 150–450mm. The gradient is also critical — drains need to fall to the outfall at the right rate (typically 1:80 to 1:100).
Can you install drainage for a new build or extension?
Yes. We install foundation drainage, surface water drainage, foul drainage, and SuDS for new builds, extensions, and development sites across Kent and East Sussex. We work with builders and developers to deliver drainage that meets planning and building control requirements.
Do you install soakaways and attenuation systems?
Yes. We install gravel soakaways, modular crate soakaway systems, and attenuation tanks for surface water management. We size them correctly for the drainage area and the soil's infiltration rate. On heavy clay, we can install attenuation tanks that release water slowly to a watercourse or sewer.
