Technical FAQs
Quick answers to common technical questions about Barrier Systems products, installation, specifications, testing and technical documentation.
Aqua Stop combines a large overall format with a high fill capacity and substantial filled mass. Each unit holds 960L of water and weighs 1,020kg when full. At 2,135mm long, 1,060mm high and 600mm wide, it provides a substantial on-site presence for visual delineation and site separation.
- 960L fill capacity per unit
- 1,020kg filled weight
- 2,135mm long, 1,060mm high and 600mm wide
No. Aqua Stop is a heavy-duty water-filled delineator, not a safety or crash barrier. It has demonstrated impact performance in low-speed environments, but it should not be used where tested redirective vehicle containment is required. For those applications, SHIELD I is the appropriate Barrier Systems product.
Aqua Stop is intended as a water-filled delineator for long runs and more exposed sites where greater filled mass is practically useful. Each unit contributes 2,000mm of effective length to the connected run, helping cover the required boundary with fewer individual units and connections. Once filled with 960L of water, each unit weighs 1,020kg, providing substantial on-site mass to help resist unintended movement. Separate drop pins form strong, secure connections between adjoining units.
- 2,000mm effective length per unit
- 1,020kg filled weight per unit
- Strong, secure drop-pin connection along the run
Site conditions, ground surface, layout and intended use should still be considered when confirming suitability.
When full, each unit holds 960L of water and weighs 1,020kg. This substantial filled mass helps the heavy-duty water-filled delineator resist unintended movement and stay put once the run has been correctly positioned and filled. Separate drop pins form strong, secure connections between adjoining units.
- 960L fill capacity per unit
- 1,020kg filled weight per unit
- Strong, secure drop-pin connections
Filled mass should not be treated as a tested movement- or wind-resistance rating. Ground surface, slope, run configuration, site activity and environmental conditions should still be considered when confirming suitability.
Each Aqua Stop unit has two top apertures for compatible mesh fencing, hazard lights or pole signage. These provisions allow additional visibility and site guidance to be incorporated along the connected run where required.
- Mesh fencing for a more continuous visual boundary
- Hazard lights for additional low-light visibility
- Pole signage for site information or directional guidance
Accessory compatibility, fittings and the complete configuration should be confirmed for the intended site use.
Yes. Linked into a continuous run, this water-filled delineator for roadworks can define temporary traffic routes, changed access points and active work-zone boundaries. Each unit contributes 2,000mm of effective length, while orange and white configurations and retroreflective tape help keep the route clearly identifiable.
- Define temporary or changed traffic routes
- Mark access points, work-zone boundaries and planned closures
- Extend visual delineation across larger roadwork areas
It can also be used as a water-filled road-closure delineator where the approved traffic-management plan requires visual guidance rather than tested vehicle containment. This water-filled traffic delineator is not crash-rated or redirective. Where tested containment is required, consider the SHIELD I redirective barrier system.
A water-filled civil works delineator can define active work areas, temporary site access routes, plant and equipment zones, material laydown areas and planned stage boundaries. Connected units form a substantial visual boundary for layouts intended to remain in place once filled.
- Define active civil and construction work areas
- Mark temporary site access routes and planned stage boundaries
- Visually separate plant, equipment and material laydown zones
Used as a water-filled worksite delineator, it provides visual delineation and site separation rather than tested vehicle containment. When selecting a water-filled delineator for civil works or a construction site, consider the ground conditions, run layout, site activity and required separation function.
The right worksite barriers depend on the function required. Where construction site barriers or temporary site barriers are needed for visual guidance, this heavy-duty water-filled delineator can define active work areas, access routes, plant and equipment zones and material laydown areas. Connected units form a substantial visual boundary for layouts intended to remain in place once filled.
- Mark temporary work-zone and construction-stage boundaries
- Define site access routes and work-area separation
- Visually separate plant, equipment and material zones
When comparing water-filled worksite barriers or water-filled barriers for construction sites, confirm whether the required function is delineation or containment. A water-filled temporary site separation barrier intended for visual guidance performs a different role from a tested traffic-containment system.
This product is not a water-filled crash barrier or water-filled redirective barrier. Where tested vehicle containment is required, consider the SHIELD I redirective barrier.
This heavy-duty water-filled delineator can form a substantial visual boundary for trenching, underground-services, utility-maintenance and infrastructure work areas. Connected runs can define temporary site routes and planned stage boundaries alongside drainage, sewer, stormwater, pipeline, pipe-laying and water-main works.
- Delineate utility excavations and active trenching areas
- Define temporary site routes and staged work boundaries
- Form longer connected lines along linear infrastructure works
Each unit provides 2,000mm of effective length and connects using separate drop pins, helping longer boundaries be formed with fewer individual units and connections. Once filled to 1,020kg, each unit provides substantial on-site mass where a more stationary delineator run is useful.
Its role is visual delineation and site separation. It is not trench shoring, excavation edge protection or a redirective vehicle barrier. Ground conditions, excavation setbacks, traffic environment, site layout and the required separation function should be considered when confirming suitability.
The displayed price supports straightforward online ordering. Where quantity, run length, timing or freight needs to be planned, Barrier Systems can prepare a project quote for Aqua Stop supply around the actual requirements.
- Required quantity or total run length
- Orange, white or mixed-colour requirements
- Required date and delivery location
- Site application and any suitability questions
Our Australian rotational-moulding capability allows project requirements to be considered alongside stock already on hand, production timing and freight planning. Availability and lead times depend on the order quantity, production schedule, destination and delivery requirements, so they should be confirmed for each project.
For quantity- or delivery-sensitive requirements, contact Barrier Systems with these details so current availability, the project quote and a practical delivery plan can be confirmed.
As a water-filled infrastructure works delineator, it can form connected visual boundaries around active work areas, temporary access routes and changing project-stage limits. Typical applications include:
- Trenching, excavation and underground-service works
- Drainage, sewer, stormwater, pipeline and water-main works
- Electrical and telecommunications installation, repair and maintenance
- Temporary access points and maintenance zones around public infrastructure
Used as a water-filled utility works delineator, it can mark work-zone limits, access points and maintenance areas where substantial visual separation is required. Its connected, high-mass format also suits planned layouts requiring a water-filled utility maintenance delineator or water-filled trenching works delineator.
When selecting a water-filled delineator for infrastructure works or a water-filled delineator for utility works, consider ground conditions, the traffic environment, access requirements, run layout and the required separation function. It provides visual delineation and site separation, but not excavation edge protection, fall prevention or tested vehicle containment.
