Job Applications
The Topcon RL-HV2S dual-slope capability opens up applications that single-slope systems cannot efficiently handle:
Parking Lot Grading and Paving: Establish precise cross-slopes and longitudinal grades simultaneously for proper drainage. The dual-axis control ensures water flows to designated collection points while maintaining ADA-compliant slopes. Asphalt and concrete paving crews use the system to set screeds and verify grade before material placement, reducing callbacks and ensuring first-time quality.
Building Pad Preparation: Create level pads or controlled drainage planes for commercial and industrial foundations. Set compound slopes to direct water away from building footprints while accommodating site topography. Excavation operators use the LS-100D receiver mounted on buckets to achieve final grade efficiently, minimizing over-excavation and costly fill requirements.
Site Drainage and Storm Water Management: Design and implement precise drainage swales, retention basins, and graded channels that direct runoff according to engineered plans. The dual-slope capability ensures water flows at the correct gradient in the intended direction, preventing erosion and standing water issues that plague improperly graded sites.
Agricultural Land Leveling: Precision land forming for improved irrigation efficiency and crop yields. Set gentle multi-directional slopes for gravity-fed irrigation or create level fields for flood irrigation systems. The extended range and long battery life make the RL-HV2S ideal for large agricultural grading projects where equipment operates across expansive areas.
Concrete Forming and Tilt-Up Construction: Use vertical mode for plumb reference when setting tall wall forms, tilt-up panels, and structural elements. The rotating laser plane provides a continuous reference around the entire work area, allowing multiple crew members to work simultaneously from a single setup. Verify panel alignment and transfer elevation to upper floors efficiently.
Trenching and Underground Utility Installation: Establish grade for sewer lines, storm drains, and other gravity-flow utilities. The laser provides continuous reference for excavation depth and slope, enabling operators to trench to specification without constant surveying. Municipalities and utility contractors reduce installation time while ensuring proper flow characteristics.

Frequently Asked Questions
- What is the range of the Topcon RL-HV2S with the LS-100D receiver?
- The RL-HV2S has a working diameter of up to 2,600 feet (800 meters) when used with the LS-100D receiver. Actual range depends on lighting conditions and environmental factors, with optimal performance in typical outdoor construction environments. In bright sunlight or dusty conditions, effective range may be reduced, though the LS-100D's enhanced sensitivity helps maintain performance where standard receivers struggle.
- Can the RL-HV2S be used for vertical applications like wall forming?
- Yes, the RL-HV2S features both horizontal and vertical operation modes. The vertical mode is ideal for wall forming, panel alignment, tilt-up construction, and vertical reference applications where plumb alignment is required. Simply rotate the laser head 90 degrees and the self-leveling mechanism automatically adjusts to provide a rotating vertical plane for layout and alignment tasks.
- What is dual-slope capability and when do I need it?
- Dual-slope allows you to set gradients on both the X and Y axes simultaneously, creating a multi-directional slope plane. This is essential for parking lot drainage, building pads with specific runoff patterns, and any grading where water must flow in a controlled direction across both dimensions. Single-slope lasers can only tilt in one direction, requiring complex calculations and multiple setups to achieve the same results that dual-slope systems accomplish in a single setup.
- Is the LS-100D receiver compatible with other Topcon laser levels?
- Yes, the LS-100D receiver works with most Topcon rotating lasers and many other brands operating on standard rotating laser frequencies. This makes it a versatile choice if you have multiple laser systems on your jobsite or plan to expand your equipment fleet. The receiver automatically detects the laser signal and provides accurate elevation feedback regardless of which compatible transmitter is in use.
