Environmental and Flood
Defencell redefines environmental protection and flood defence with a lightweight, deployable cellular system engineered for rapid, sustainable solutions. Our versatile cellular technology stabilize ground, reinforce roads and create robust flood barriers that safeguard infrastructure in changing conditions.
Defencell addresses challenges from erosion control and camp winterisation to emergency flood protection, all while using environmentally neutral materials. The modular design and structural efficiency of Defencell enable engineers and emergency responders to implement resilient, rapidly deployable defences tailored to diverse environmental and operational challenges.
Defencell Ground Stabilisation (GS) is truly versatile and proven in a wide range of civil engineering applications. The strong lightweight cellular panels are ideal for providing surface stabilization or ground reinforcement and yet single panels are man portable and simply deployed by hand or using MHE.
Defencell GS panels are manufactured in various sizes, heights and cell diameters to suit many tasks and ensure that supply routes remain open.
The advanced cellular structure improves load distribution, reducing differential settlement under varying conditions. Its permeability allows for efficient drainage, mitigating the risk of water accumulation and soil erosion.
The process of using a layer of geotextile before laying aggregate when building roads and railways has been proven over many years. Adding a cellular reinforcement to this construction creates roads and paths of enormous durability during seasonal fluctuations in temperature, rainfall and traffic.
Defencell GS is also completely non-metallic and is therefore ideal for use in areas where environmental considerations prevent the use of more permanent or chemically aggressive products including metals or hard plastics.
The interlocking cellular structure distributes loads efficiently, reducing subgrade stress and minimizing rutting. This improves the long-term performance of unpaved roads, particularly in areas with weak or variable soil conditions.
Using Defencell GS to build an elevated and free draining platform gives the reassurance of a year round hardstanding area for cars, trucks and buses despite localised weather conditions.
The addition of advanced cellular system stabilizes the fill material or laying a suitable protective covering provides an easily installed and economic surface. The modular design allows for quick installation and adaptation to specific helicopter operational needs, providing a stable, load-bearing surface for aircraft.
Its robust unique bi-component construction ensures minimal soil displacement and effective drainage, preventing surface degradation during frequent helicopter landings.
Using Defencell GS to provide a stable surface for building camps, siting modular buildings and to cover essential environmental services like drainage adds to effective design. Aid organisations and military commanders often have to build camps in areas where transportation routes converge, in flood plains or wadis and the ability to ensure consistent ground conditions is a significant advantage.
Cellular structure provides reliable support on soft or uneven ground, minimizing settlement of structures. Defencell lightweight, modular panels make it easy to deploy and relocate as required. Moreover, the system’s resilience to harsh weather conditions ensures that camp infrastructure remains stable in fluctuating environments.
Defencell is environmentally neutral and completely non-metallic. Many years of experience in the geotechnical world have proved the versatility of the Defencell cellular structure. The system is proven for erosion and sediment control, river bank reinforcement, silt fencing and various groundwork water management applications.
The durable advanced cellular confinement construction adapts to the terrain while offering excellent structural strength and is well suited to rough ground to reduce erosion and promote vegetation. Mulch or fill from the site can be used. Water filters through while fill material and soil particles are retained by the cell wall. Defencell can be emptied and re-used as necessary and this adaptability allows for long-term performance in challenging environments.
Defencell has been proven in action, and in thorough testing, to be an effective and easily installed Flood Protection barrier. Using Defencell to build new defences, enhance existing protection measures or reinforce weakened levees ensures that communities, towns and farms are protected. Tested by the U.S. Army Corps of Engineers, Defencell Flood Walls significantly outperform sandbags through:
- Faster installation and removal time
- Less water seepage
- Better overall system endurance
A simple one metre high (or just 0.50m) wall will be sufficient to stop all but the most extreme flooding. Adding this to an existing levee or embankment is a quick and easy solution and many times faster than installing the equivalent barrier using sandbags.
Testing has shown Defencell to be many times faster to install than sandbags and also much faster and easier to remove when the threat has passed. Reports on deployments on the Ohio River in the US, Murray River in Austraila and in Ontario, Canada have proved the operational capabilities of Defencell.
