The loop is the part you will see for two weeks and never again.
A ground loop is plastic pipe that carries water to the ground and back. It goes down in bores or out in a trench, connects to headers at the house, and is buried once it has been flushed and pressure-tested. After that it is a lawn.
Two ways to lay a loop.
Vertical bores
Holes a few hundred feet deep, a few feet apart in a row or a grid. They need little surface and cost more per foot to drill.
Best for small or sloped lots
Rig works from the drive or lawn
Bore depth depends on soil and rock
Horizontal trench
Pipe laid in a trench a few feet down. It needs more open ground and less drilling.
Needs open lawn or a field
Excavator and trench to restore
Lower cost where the ground allows
What the drilling days are like.
- 01
Step 1: The rig arrives
A truck-mounted rig and a support truck need a path and a place to stand.
- 02
Step 2: Drilling
Noisy and muddy. Cuttings and water come up and are contained on site.
- 03
Step 3: Pipe goes in
The loop is lowered into each bore and grouted.
- 04
Step 4: Connecting and testing
We join the loops, flush the system and test the pressure.
- 05
Step 5: Restoration
Ruts are filled, the trench is closed and seed or sod goes down.
What we agree on before the rig comes.
The path
Where the rig drives, and what is protected along the way.
The restoration
What we repair, what we leave to you and what we do not touch.
Utilities
Locating lines before any digging, and who calls it in.
Walk the lot with us.
