Job Applications
Residential Foundation & Slab Work: Establish a consistent elevation reference across the full footprint of a residential foundation pour. The LL1505C-X2's working range and self-leveling accuracy keep layout crews efficient from corner stake to corner stake.
Interior Finish & Ceiling Work: Use the rotating laser plane to align suspended ceiling grids, set uniform floor elevations, and transfer benchmark heights between floors — all with one instrument setup.
Commercial Site Prep & Grading: The HL450 receiver and grade rod combination allows a single operator to check cut-and-fill grades across a commercial pad site, reducing the need for a two-person crew on routine grade checks.
Utility & Drainage Layout: Set consistent pipe grades and drainage slopes by using the receiver-assisted range to verify invert elevations and maintain specified fall across longer runs.
