Stormwater Pits, Subsoil Drainage and Ag Line Installation
We are on hand to install subsoil drainage solutions to stop surface water sitting in your yard
The drainage work that actually fixes the problem
Surface drains move water that is already on the surface. When the ground itself stays wet, when water sits under the slab, or when the stormwater has nowhere to go, the fix is below ground and it needs to be engineered rather than guessed.
We install stormwater pits, subsoil drainage, ag lines and charged systems across the Hills District, north west Sydney and the Hawkesbury, with our own machinery.
The Drainage Solutions we install For Homes and Properties
Stormwater pits and grated pits
Pits installed at the right levels, connected properly, with grates suited to the traffic going over them. A pit at the wrong level moves nothing.
Subsoil drainage
Where the problem is water in the ground rather than on top of it. Subsoil lines intercept it and take it somewhere useful instead of letting it sit under a slab, a driveway or a lawn.
Ag line and agi pipe installation
Slotted pipe in aggregate, wrapped and laid to fall, which is the part most DIY installs get wrong. Laid flat or unwrapped it silts up and stops working within a season.
Charged stormwater systems
Where the stormwater has to run below the outlet and rise to discharge, a charged system does it without a pump. They have to be sealed, laid and vented correctly, and they need a way to be cleaned out.
Stormwater connections and re-routing
Connecting to the legal point of discharge, or re-routing a system that was never right.
Retaining wall and behind-wall drainage
The right drainage is crucial behind retaining walls. If water has no where to go, the force of wet ground behind the wall is what causes it to fail and create a landslide.
Detention and retention tanks
Where a development approval requires on-site detention, we install and plumb the tank to the approved design. The tank itself comes from the manufacturer, and we handle the excavation, the install and the connection.
Pump wells and stormwater pumps
Where gravity cannot do it.
Excavation and trenching
Our own machinery, so the dig is not a separate booking and a separate delay.

What Sydney Locals Say About Us
How we work out what the property needs
- We look at where the water actually goes. Not where the plan says it goes. On most problem properties those are different.
- We find the legal point of discharge. Everything downstream of that is decided by it.
- We check the fall. Most failed drainage is a fall problem, and no amount of extra pipe fixes it.
- We work out whether it is surface or subsoil. Those are completely different jobs. Putting a surface drain on a subsoil problem is the most common wasted spend we see.
- We tell you what it will and will not fix. If the answer is bigger than you were hoping, we would rather say it before the machine arrives.
