Sequential Barrier Engineering
How the 3-Zone Barrier Protects Your Building
Over 80% of interior floor dirt is tracked in on footwear. Selecting a multi-zone barrier systematically strips coarse grit outside, absorbs pedestrian water in the foyer, and neutralises residual moisture before visitors reach internal finishes.
Coarse Grit Scraping
Outside Entry Threshold
Positioned immediately outside the doorway to scrape off heavy gravel, mud clods, and coarse dirt before visitors cross the building threshold.
- Heavy-duty aluminium scraper blades
- Corrosion-resistant anodised finish
- Open drainage channels for water runoff
Recessed Aluminium System
Main Entrance Foyer Well
Installed in a flush recessed mat well. Combines dual-action aluminium scraper extrusions with dense absorbent carpet inserts to capture fine grit and absorb bulk moisture.
- Custom fabricated flush recessed depth profiles
- AS 1428.1 DDA compliant & wheelchair-friendly
- Primary absorption and particle control
Secondary Drying Mat
Inner Lobby & Lift Vestibule
Positioned in high-traffic corridors and lift banks to ensure footwear and wheeled equipment are thoroughly dry, eliminating slip hazards on internal polished stone or timber.
- High-capacity microfibre drying inserts
- Protects interior timber, vinyl & tiles
- Reduces commercial floor cleaning costs
The Engineering of Mat Length: Sizing vs. Soil Containment
Most building dirt and moisture is tracked in on shoe soles. Selecting an optimal walking length directly protects internal floor finishes:
1.8 Metres
Initial Coarse Grit Removal
Basic entry threshold barrier for light commercial traffic.
3.0 to 4.0 Metres
Fine Dirt & Bulk Moisture Trap
Commercial standard for corporate building lobbies.
6.0+ Metres
Complete Slip & Soil Neutralisation
Optimal barrier for high-traffic shopping centres, hotels & hospitals.
Compare TC Series Infill Systems
Select the optimal surface insert, scraper combination, and traffic rating tailored to your building's entryway architecture.
Carpet Insert System
Solution-dyed polyamide carpet ribs designed for high-volume pedestrian moisture absorption and fine dust capture in internal lobbies.
Aluminium + Carpet Ribs
Alternating architectural aluminium scraper bars and carpet inserts. The industry standard for retail, healthcare, and office towers.
Carpet & Brush Infill
Dual-action system combining heavy-duty monofilament brush bristles with moisture-absorbing carpet inserts for aggressive dirt scraping.
Heavy-Duty Brush Infill
Multi-row stiff nylon brush bristles engineered for external air-locks and outdoor covered approaches to remove heavy soil and gravel.
Entrance Mat Dimensioning & Edge Framing Types
Understanding traffic orientation, sizing conventions, and perimeter recess framing ensures 100% AS 1428.1 barrier-free compliance and seamless installation.
1 Sizing Guide: Width (a) vs. Walking Traffic Direction (b)
Key Dimensioning Rules:
- Dimension (a) = Width: Length of aluminium extrusion rails across the doorway opening.
- Dimension (b) = Walking Depth: Distance traveled along the traffic flow from entry to exit.
Architectural Placement:
- Optimal Mat Depth: Minimum 1.8m to 2.4m depth for 3–4 full pedestrian footstrikes.
- Door Clearance: Aligns with automatic sliding or revolving door thresholds.
2 Edge Profiles & Framing Choices (Order Types)
Recessed Well Fit
Fits directly into existing concrete screed recess flush with surrounding floor tiles or timber.
Single Bevel Ramp
Surface mounted with aluminium transition ramp on the entry approach side against a wall or door threshold.
Dual Bevel Ramp
Full surface-mounted application with safety bevel ramps on both entry and exit edges to prevent tripping.
Perimeter Angle Frame
Supplied with pre-mitred aluminium L-angle frame for new screed installation and clean architectural edge finish.
3 3-Zone Clean-Foot Filtration Architecture
Coarse Scraping
Exterior zone removes heavy gravel, soil, and mud before entering the building.
Fine Dirt & Grit Scrubbing
Intermediate zone captures fine dust, sand, and moisture inside revolving doors or air-locks.
Moisture Absorption & Drying
Internal lobby zone eliminates remaining dampness, preventing slip hazards on polished hard floors.
