Sub-surface drainage

Sub-surface drainage carries water away from where it causes problems. Standing water on lawns, patios and around buildings often points to a drainage issue that is worth addressing.

  • Sub-surface drainage systems
  • Drainage solutions to help prevent water pooling
  • Ground preparation for drainage runs

The correct solution depends on the property and site conditions, which is why we assess the site first.

Water pooling

Dealing with water pooling

Pooling can come from compacted ground, poor levels, blocked or missing drainage, or run-off from nearby surfaces. We look at the cause rather than applying the same fix everywhere.

  • Look for standing water after rain
  • Notice damp or soft ground near buildings
  • Check whether levels slope towards the house or patio

Reshaping levels may also be part of the answer. See groundworks.
