Best Practices for Floor Level Transitions in Commercial Units
Sudden drops can damage equipment, trip pedestrians or overload machinery. In this guide, we’ll share best practices for specifying and installing level-change solutions, including ramps, threshold seals and specialised profiles. For an in-depth look at threshold-seal benefits, start with Why Every Warehouse Should Install Threshold Seals.
1. Assessing Your Level Change
Measure Height Difference
Use a spirit level or laser tool to record the vertical gap at multiple points — uneven floors require ramped or tapered solutions.
Traffic Type
Consider forklift wheelbase, pallet-truck dimensions and pedestrian flow to determine maximum slope (typically ≤ 1:12 for wheeled traffic).
Load Requirements
Heavy machinery may need gentler transitions; check manufacturer specs for maximum incline.
2. Ramps & Tapers
Portable Dock Ramps
Ideal for flexible loading-bay use; rated by weight capacity and anti-slip surface.
Fixed Concrete/Fibreglass Ramps
Permanent installations can be cast or bonded in place; finish with anti-skid coatings.
Tapered Thresholds
Aluminium transition profiles provide a ramped edge to bridge minor drops (up to 15 mm).
3. Integrating Threshold Seals
Dual-Function Profiles
Some GaraDry® Commercial Threshold Seals offer a tapered leading edge that eases level changes while sealing.
Hybrid Solutions
Pair standard seals with bespoke ramp sections to maintain water defence and facilitate smooth passage.
Installation Tip
When using ramps, ensure the threshold seal is set back 5–10 mm from the ramp face to avoid compression issues.
4. Surface & Material Selection
Anti-Slip Treatments
Apply grit-filled epoxy or PU coatings on ramps and thresholds to maintain traction under wet or oily conditions.
Chemical Resistance
In food or chemical-storage areas, choose EPDM-lined seals and acid-resistant ramp surfaces.
Thermal Stability
For freezer or external doorways, select materials rated from –40 °C to +60 °C.
5. Maintenance & Inspection
Monthly Checks
Inspect ramps and seals for chips, cracks or de-lamination.
Traction Renewal
Replenish anti-slip grit every 12–18 months in high-traffic zones.
Alignment Verification
Confirm no drift or shifting of ramp units — tighten anchors or apply fresh adhesive as needed.

Conclusion
Effective floor-level transitions are a blend of accurate assessment, the right materials and proper installation. By combining well-designed ramps, tapered profiles and GaraDry® threshold seals, you’ll create safe, smooth pathways for forklifts, pallet trucks and staff — boosting productivity and minimising incidents.
