Standing water, waterlogged lawns and patios that puddle are usually a groundworks problem, not a planting problem. Most of it comes down to falls, sub-base and where the water is meant to go.
We build the drainage in as part of the garden. We are landscape contractors who do drainage, not a drain-clearing or drain-unblocking company. We don't do garden maintenance or mowing.
It's all groundworks: the levels, the excavation and the sub-base set before any surface goes down.
What garden drainage solutions do you install in Surrey?
Drainage work we carry out across Surrey, from a single soakaway to a full garden system:
Land drainage and French drains
Perforated pipe, shingle and geotextile membrane, laid to fall.
Soakaways and crate systems
Sized and sited to take roof and surface water away from the house.
Channel and slot drainage
Aco channels across patios, driveways and thresholds.
Linear drainage and gullies
For driveways and hardstanding.
Patio and paving falls
Correct sub-base, correct fall, water off the slabs instead of sitting on them.
Permeable driveway build-ups
Where surface water has nowhere to go.
Lawn drainage
Regrading, sub-surface drains and rebuilt topsoil profiles before new turf.
Retaining and sleeper wall drainage
Drainage layer, membrane and weep holes behind the wall.
Downpipe and rainwater connections
Into new or existing runs. [CONFIRM: whether Carmen Landscapes connects to mains/foul drainage or only surface water and soakaways].
Pond and pool surround drainage
As part of a wider build.
Anything requiring connection to a public sewer is subject to the relevant approvals: [CONFIRM: how Carmen Landscapes handles Thames Water / building control approvals for sewer connections].

Why is my garden waterlogged?
Common causes, in plain terms:
- •Clay subsoil that holds water.
- •Compacted ground from a build or an extension.
- •Patios and paving laid flat, or laid to fall towards the house.
- •Missing or blocked soakaways.
- •Roof water discharging straight onto the lawn.
- •Ground levels running towards the property.
- •Thin topsoil over rubble left by a previous contractor.
We dig test holes and look at the levels before we quote, so the fix matches the cause.
