Solutions for tomorrow

Effective Flood Risk Mitigation

Flooding is an increasing global challenge, driven by population growth, urbanisation, and climate change. These factors place immense strain on infrastructure, raising the risk of flood events that can devastate properties and communities. Fortunately, with the advancements in technology and flood prevention solutions, we can now mitigate these risks and protect our homes and businesses.

 

Our flood protection solutions are specifically designed for homeowners, engineers, and government bodies in flood-prone areas.

We offer a comprehensive solution that integrates seamlessly with existing infrastructure while complying with regulatory standards.

Understanding Flood Risks

Before diving into our solutions, it’s important to understand the severity of flood risks. Heavy rainfall is one of the main triggers for flooding, but other factors such as inadequate drainage systems, land development in floodplains, and natural disasters like hurricanes can also contribute to floods. As climate change continues to cause extreme

The True Cost of Flood Damage

The impact of flooding goes far beyond the immediate, visible destruction of valuable property like cars, furniture, and electrical systems. There are also severe, long-term effects that are not easily seen but can lead to significant health problems and, in the worst cases, structural failure.

Hidden Damages from Flooding:

  • Structural Overload: The force of floodwater can put buildings under extreme stress, causing fatigue in critical components like beams and foundations, which may eventually lead to collapse.
  • Mould and Health Risks: Lingering dampness creates a breeding ground for mould. The resulting spores can harm the health of people and animals using the property and destroy essential wooden structural elements.
  • Electrical and Fire Hazards: Water ingress causes corrosion in electrical systems, which can result in malfunctions, short circuits, and fires.
  • Component Degradation: Metal components, such as reinforcing bars in concrete, door frames, and beams, can erode when exposed to water, weakening the building’s stability over time

Common Causes of Property Flooding

Flooding can happen anywhere, and the effects are often worsened by local changes like higher road levels or new fencing along waterways.

Key Flood Triggers:

  1. Heavy Rainfall (Flash Floods): Intense downpours can lead to rapid surface water flooding when the ground cannot absorb the water fast enough.
  2. Overrun from Neighbours: Poor drainage on adjacent properties can cause water to flow onto your land.
  3. Backflow from Drainage Systems: Public sewer and drainage systems can become overwhelmed, forcing contaminated water back into properties.
  4. Lack of Drainage: A property without an effective drainage system is highly vulnerable to flooding.
  5. Location Below Waterline: Properties located in low-lying areas face a constant and elevated flood risk.

Urban areas are often under development, which can lead to damaged or insufficient drainage infrastructure. This prevents water from exiting an area quickly, causing flooding to local communities and properties. Basements, underground car parks, utility wells, and ground-level utility installations are particularly high-risk areas.

Basic Flood Prevention Strategies:

Effective flood protection starts by stopping water from getting in. This is typically achieved by building up the ground level or constructing permanent flood walls where possible, which is often the most cost-effective long-term solution.

  • Flood Barriers: Install permanent or temporary barriers to block water.
  • Mechanical Drainage: Use flood pumps to actively remove water from critical areas.
  • Backflow Valves: Fit backflow valves or drain stoppers to prevent sewage and floodwater from entering through the drainage system.
  • Waterproofing: Apply waterproof coatings to walls and floors.
  • Elevate Critical Utilities: Raise electrical installations and other essential equipment above the potential flood risk level.

Recommended materials include waterproof concrete, brick walls, and metals that can withstand water pressure.

For openings needed to access the property, it is best to install floodproof doors and windows. Alternatively, quick-to-install demountable or Passive flood barriers are an excellent option for car and lorry entrances.

The AS FRIIS Approach to Flood Protection

At AS FRIIS LTD., our focus is on creating low-maintenance, reliable flood protection solutions that work when required. Through our partnerships with industry leaders , we develop and provide tailored solutions for flood mitigation that protect lives and assets in private homes, industrial facilities, commercial buildings, and municipalities.

Our collaborative process includes:

  1. On-Site Risk Evaluation: We work with your operational teams to understand current challenges and historical flood problems at your site and in the surrounding area.
  2. Custom Design Development: Using the collected data, we create a basic design for flood protection. We aim to find the most effective long-term solutions, often involving simple changes to the property’s infrastructure that can be implemented.
  3. Feature and Benefit Discussion: This is a crucial part of our process. We cover all aspects, from protection levels and investment costs to daily operational impacts and long-term maintenance needs.
  4. Implementation and Training: We can oversee the installation and provide training if required to ensure your team is prepared.

AS FRIIS also offers regular flood-proofing audits to ensure that all prevention equipment is properly maintained and to inspect the property for any changes that could increase the risk of flooding.

Flood protection solutions we provide

Cold Flood Prevention mobile wide area flood protection barrier

Fast deployable flood protection barrier for versatile use in flood protection and controlling water flow.

Cold Flood Prevention is a unique modular system, which consists of a series of elongated sections that can be attached to each other and thereby the length is easily adaptable to suit the extent of the flood.

The barrier is filled with water, which creates a massive pressure that seals the surface and enables the barrier to withstand and divert floodwater. The barrier’s cellular construction ensures that it remains stable on any surface irrespective of external conditions making the barrier extremely robust and highly effective in preventing flooding. Available in heights from 420 mm up to 1,1170 mm flood protection heights.

Friiva® Gate & Fence Flood protection barrier

Fast and easy deployable aluminum flood protection barrier for fences, gates and doors

Friiva Gate and Fence barriers is a unique modular system made from aluminum. The system is versatile and can be customized to most height and length requirements to protect building or areas as required.

The barrier panels and posts are constructed in durable aluminum alloy. The aluminum barrier panels provide flood protection in vertical increments of 200 mm logs/planks.

The barrier panels stack on top of one another and most applications can be installed by one person.

Dam Easy® Door & Gate Flood protection barrier

Fast and easy deployable composite flood protection barrier for gates and doors

Dam Easy offers an excellent alternative to heavy and messy sandbags, this barrier provides the first line of defense to prevent water from entering doors and windows in your home.

When flooding happens, the ability to act quickly is critical. This flood protection barrier provides you with reliable flood protection at your fingertips as it can be installed in under 5 minutes! The Dam Easy door is 720 mm height and easily offers flood protection up to 600 mm

Drain stoppers & accessories

Easy deployable drain stoppers and back flow valves.

The increasing extreme climate puts an enormous pressure on drainage systems. Heavy rainfall often overwhelms the drainage system that cannot cope with the massive water runoff. This results in flooded and contaminated areas around the systems as well as dangerous situations when manhole covers are opened to cope with the excess water.

AS FRIIS offers a range of products from Drain stoppers, Knife gate valves and back flov valves to mitigate flooding from drains and wells.
