Drainage installation to prevent basement water pooling and flooding issues- Newtown

Basement Flooding Prevention - Stormwater Sydney

Subsoil Drainage

When it pours and the rain doesn’t drain away, water collects because it has nowhere to go. Saturated soil cannot move water in the ground fast enough to make way for surface water to trickle through. Excess water can wreak havoc on your backyard and home, killing plants and damaging masonry and brickwork. areas below ground level such as basements and carparks can also collect water runoff from driveways or seepage through retention walls.

The most common type of subsoil drainage is an underground pipe made from a porous material. The pipe has numerous holes to allow water to seep through, while the permeable material serves as a barrier that prevents soils and debris from entering and causing a blockage. Rocks and pebbles are also sometimes used to filter the water. In some instances, re-levelling the land may be an effective way to channel water away from the property and eliminate moisture build-up underground.

Summary of the Drainage Installation

Our clients were a strata committee in Newtown, Sydney experiencing flooding and water pooling in their basement car park. They desperately needed a drainage installation. A lack of sufficient drainage led to water damage to the building and personal items kept in the basement during rain events. Our team cut out the bordering concrete floor of the basement and dug out a new subsoil drainage path to allow proper drainage of water runoff during heavy rainfall and prevent any water pooling on the basement floor.

Background

The Building was experiencing water ingress and ponding in the basement carpark during heavy rain events. The property already had Sub-soil drainage to one side of the basement but required more at one end.

The Scope of Services:

  1. Concrete saw channel for Sub-soil drainage
  2. Supply and installation of Sub-soil drainage (approx. 18M)
  3. Cut hole in wall
  4. Backfill with blue metal
  5. Remove and dispose of dirt and concrete
  6. CCTV existing Sub-soil drainage line
