Trenchless Wire Burial · Nashville & Middle TN
Low-voltage cable run beneath an established lawn with the L2 Line Layer — the only machine of its kind in the Nashville market.
What We Do
Trenchless wire burial is the practice of running low-voltage lighting cable beneath an established lawn without trenching, using a precision blade machine that slices a narrow path and pulls wire through it. Light TN performs trenchless wire burial across Middle Tennessee with the L2 Line Layer — the only machine of its kind in the Nashville market — reaching large, sloped lots without scarring the turf.
Light TN is a family-owned landscape lighting designer in Burns, Tennessee, and the only company in the Nashville market running the L2 Line Layer. The studio uses it on 500+ Middle Tennessee projects since 2020, installing to licensed contractor CE-D: 76580 standards so an established lawn stays whole.
The Craft
The method serves the design, so light goes exactly where the property needs it. Fixture placement isn't limited by how much lawn you'll dig up — cable can reach a back-corner specimen tree without tearing up the grounds in between.
You're left with an intact lawn: no trench scar across turf that took years to fill in. The L2 Line Layer slices a thin path through the soil, the cable is drawn down into it, and the turf closes back over with minimal disturbance.
What's Included
Low-voltage cable burial — 12-volt cable run beneath the lawn with minimal disturbance, no open trench.
The L2 Line Layer — a precision reciprocating-blade machine that slices a thin path and pulls wire down into it.
Reach across the property — cable run to the far, sloped corners of a large lot without tearing up turf.
Clean, concealed runs — wire kept out of sight as part of craftsmanship that disappears.
Standards-based install — performed to licensed contractor CE-D: 76580 standards.
An intact established lawn — turf that took years to fill in is left whole, not cut open and reseeded.
Who It's For
Trenchless wire burial is for established lawns that conventional trenching would scar, and for large or sloped lots where fixtures sit far from the power source. On heavy-clay Middle Tennessee properties, trenches recover slowly — so the method matters most where the turf is finished and mature.
It suits homeowners adding lighting to a finished landscape and designs that need to reach the far corners of a property. Middle Tennessee's heavy clay makes trenching across a finished lawn a scar that takes a season to heal. We bury low-voltage wire with the L2 Line Layer — the only trenchless machine of its kind in the Nashville market — so cable goes in and your established turf and beds stay whole.
Our Process
Cable paths are mapped to the lighting design and fixture layout before any blade touches the soil.
The L2 Line Layer cuts a thin path through the soil — a narrow slit, not a wide strip of removed sod.
Low-voltage cable is drawn down into the path the machine has cut.
The turf closes back over the path with minimal disturbance, leaving the lawn intact.
Cable is connected to the transformer and zones, then verified to licensed contractor CE-D: 76580 standards.
What Sets Light TN Apart
A trenchless capability most installers in the Nashville market can't offer. The only L2 Line Layer in the market.
Reaching a back-corner specimen tree without damaging the grounds. Craftsmanship that disappears — clean, concealed runs alongside shielded fixtures.

FAQ
Light TN defines trenchless wire burial as running low-voltage lighting cable beneath an established lawn without an open trench, using a precision blade machine that slices a narrow path and pulls wire through it. The turf closes back over with minimal disturbance.
Light TN uses the L2 Line Layer, a precision reciprocating-blade machine and the only one of its kind in the Nashville market. It cuts a thin path through the soil and pulls the cable down into it, so there is no open trench or wide strip of removed sod.
Light TN's trenchless method leaves a minimal, quickly-closing path rather than the scar a conventional trench creates. On Middle Tennessee's heavy clay, this keeps an established lawn intact instead of cut open and reseeded.
Light TN uses trenchless burial specifically to reach the far, sloped corners of large lots that trenching would tear up, so fixture placement isn't limited by how much lawn you're willing to dig.
Light TN buries 12-volt low-voltage cable, which is safe to run beneath a lawn, installed to licensed contractor CE-D: 76580 standards. The low voltage and proper burial depth make the system safe around planting and play areas.
Light TN runs the only L2 Line Layer in the Nashville market, so this specific trenchless capability is not something every installer can offer. Many still trench, which is what leaves a visible scar across a lawn.
Light TN can perform trenchless burial year-round in Middle Tennessee, with the method causing minimal disruption regardless of season. The on-site design sets the timing alongside the rest of the installation.
Light TN includes trenchless burial as part of its installation rather than a separate premium, with overall pricing set after the on-site design. Projects over $10,000 carry a 15% deposit, smaller projects require none, and the consultation is free.
