Why choose a DENIOS Pop-Up Barrier?

  • For Spills...

For enterprises engaged in chemical storage, the constant risk of leaks and spills remains a concern. The implementation of a Pop-Up Spill Barrier presents a viable solution. This barrier can be set up either to segregate incompatible substances within a sizable facility or to effectively confine potential spills and sprinkler discharges at every entrance point around the facility's perimeter.

  • For Floods...

The occurrence of floods can lead to harm, affecting storage spaces, machinery, and merchandise. Surprisingly, more than 80% of flood-related losses arise from water levels under 15 inches. By opting for an FM-Approved Pop-Up Flood Barrier, you can establish a safeguard mechanism for exterior entrances. This measure effectively shields the lower-level entryways of your facility or accommodates adaptations in its design and usage to counter flood threats.

What are the benefits?

  • Requires no electricity or human intervention

  • Activates instantly

  • Provides a seamless, obstruction-free doorway opening

  • Occupies no space as it's recessed inground and flush with the floor

Stay Protected from Floods: Discover the DENIOS Pop-Up Flood Barrier

Traditional methods often fail to protect industrial facilities from floods, exposing businesses to costly damages and operational disruptions. A reliable and efficient flood control solution is crucial for safeguarding assets, ensuring business continuity, and protecting personnel.

Introducing DENIOS's revolutionary Pop-Up Flood Barriers. Designed to provide automatic flood protection, these barriers eliminate the need for manual deployment, conserving valuable time and resources during critical flood events. When rising floodwaters are detected, the barriers deploy rapidly, creating a watertight seal that protects equipment, inventory, and personnel from damage. Please view our video demonstration to see how DENIOS Pop-Up Flood Barriers can transform your flood preparedness strategy.

DENIOS' Pop-Up Flood and Spill control barrier provides an uncomplicated and automated solution for industrial facilities. Let's delve into their functionality:

  • Passive Design: Employing a self-contained and passive design, these barriers are crafted from robust stainless steel. Their weighted base enables them to remain flat when not in use, eliminating the requirement for extra floor space and ensuring unhindered traffic flow.

  • Automatic Deployment: The barrier's integrated mechanism operates on a float system. As liquids, whether floodwater or spills, enter the barrier's collection sump, the float displaces them, activating the automatic deployment of the wall.

  • Swift Action: This automatic process occurs immediately upon contact with liquids, ensuring a rapid response to spills and floods. The barrier wall efficiently prevents liquids from infiltrating your facility, reducing potential damage and downtime.

  • Watertight Seal: When floodwater makes contact, the barrier forms a watertight seal for flood control. This prevents floodwater from infiltrating, thus safeguarding your valuable equipment, inventory, and personnel.

  • Easy Reset: After the flood or spill has receded, resetting the barrier to its original flat position is effortless, readying it for any future potential events.

In summary, DENIOS Pop-Up Flood and Spill Barriers provide a convenient and trustworthy solution for industrial facilities. With their automated design and rapid response time, they mitigate damage and guarantee the safety of both your personnel and property.


Downtime is a significant expense for industrial facilities. That's why DENIOS Pop-Up Flood and Spill Barriers are tailored to fit seamlessly into your daily operations. When inactive, these barriers lay flat in doorways, facilitating unimpeded movement of personnel and vehicles. This eliminates the necessity for ramps or berms, ensuring a streamlined workflow and minimal disruption to your activities.

Compact Design: Effortless Incorporation into Your Facility

Industrial facilities frequently contend with limited floor space. DENIOS Pop-Up Flood and Spill Barriers tackle this challenge with their space-efficient design. When not in use, they seamlessly blend into existing doorways, demanding no extra floor space. This enables you to prioritize critical production or storage areas without sacrificing flood and spill protection.

How a DENIOS Spill Barrier Could Have Prevented Environmental Damage

In 2023, a major fire erupted at a chemical distribution facility in North America, resulting in significant damage and a subsequent chemical spill that contaminated nearby water bodies. The discharge of water from the fire sprinklers, when mixed with flammable chemicals, generated what fire experts term "fire water." This ignited fire water led to the rapid spread of a floating fire, causing extensive destruction to the facility and posing challenges in containment. The specific chemicals involved were not disclosed, but they inflicted substantial harm on wildlife in the affected region. The cleanup operation lasted several months, sparking concerns regarding public health and environmental safety. Additionally, hefty fines loomed over the company, casting doubt on its financial recovery..

How the Implementation of a DENIOS Spill Barrier Could Have Averted Environmental Harm

A DENIOS Pop-Up Spill Barrier installed within a containment room could have greatly mitigated environmental damage in a chemical plant fire scenario similar to the one depicted. Here's how:

  • Automatic Deployment: In contrast to conventional approaches that rely on manual intervention, the DENIOS barrier triggers automatically upon liquid contact, including firewater. This rapid reaction could have confined both the water and burning materials within the containment room.

  • Watertight Seal: The barrier's structure establishes a waterproof seal, halting the spread of contaminated firewater and averting its leakage into adjacent water bodies. This measure would have notably restricted the extent of the area impacted by hazardous chemicals.

  • Reduced Environmental Impact: By confining the firewater and burning materials, the barrier had the potential to avert a significant release of hazardous chemicals into the river. Consequently, this action would have safeguarded the fragile ecosystem from severe damage.

Although DENIOS barriers cannot prevent fires directly, their automated and efficient containment features could have greatly reduced the environmental repercussions of this incident.

Frequently Asked Questions

What are Pop-Up Flood and Spill Barriers?

Pop-up flood and Spill Barriers are automatic flood control and spill containment systems designed for industrial facilities. They deploy instantly upon contact with liquids.
