FIELD APPLICATIONS

What contractors use this accessories for

01

Concrete Pad Grading

Set the laser on tripod at your pad reference point, use the CR700 receiver to confirm rod readings across the pour area, and get consistent height and slope for proper drainage and finish. This workflow cuts layout time and gives your concrete crew confidence in elevation before pouring.

02

Foundation Excavation and Site Prep

Use the horizontal beam to establish grade lines for footing depth and subgrade elevation across multiple stakes and offsets. The vertical capability lets you check wall plumb and pier height, making this laser do double duty on excavation and formwork setup.

03

Landscape Drainage and Grading

Grade slopes for swales, berms, and drainage paths by shooting multiple rod positions and comparing readings to your target slope line. The INCHES rod and single slope laser keep the math simple and the grade accurate on residential and light commercial landscape work.

04

Driveway and Parking Lot Slopes

Establish and verify proper crown and cross-slopes for asphalt or concrete drive work by shooting elevation at key points across the width. The red beam visibility and quick CR700 detection speed up layout on long, narrow projects.

05

Grade Stake Setup and Verification

Set cut and fill stakes on a grading project by establishing your reference datum with the laser, then take rod readings to determine required elevation at each stake. Use the vertical beam for plumb checks on tall stakes or column references.
