3 3.5 Maximum installable height 1.80m 3.6 Design for or behaviour around curves/arcs/corners The standard straight elements can be moved 5 degrees up/down and back/forward. There are also corner elements to accommodate 30, 60 and 90 corners. New corner elements have 45 inner or outer corner. Inner length 1.77 meter Outer length, 1 Meter compare technical drawing Technical drawing is attached 3.7 Number of vertical joints/sealings (per unit / unit width) Two per unit, joining with the next unit or end support fixing. 3.8 Number of horizontal joints/sealings (per unit / unit height) Two per unit. One, which makes a seal with the ground surface and one joining the lower panel with the upright panel. 3.9 Width of structure at base (installed state) Available in 0.75, 1.20 (standard) and 1.8 meters Required storage area per unit (packed dimension) 1 standard unit: 2.10m (l) x 1.20m (w) x 0.15m (h) Recommend to store the elements on special pallets: 1 pallet + 7 standard. elements: 2.15m (l) x 1.27m (w) x 1.10m (h) Weighing a total of: 500kg 4. STRUCTURAL ASPECTS 4.1 Likely modes of failure Overtopping Rolling Sliding Collapse Breach Overturning Seepage

4 This has been tested as part of the certification done at the Technical University of Hamburg 4.2 Maximum design head of water Same as height of each element. Please provide details for each available unit height 4.3 Behaviour subject to seepage and water tightness Some seepage (less than 40 litres per hour per metre) 4.4 Damage/Tear/Puncture. How does the product behave after damage? Almost all parts can be exchanged. Minor damages from impact have no effect on the stability of the system during an operation. 4.5 Does the product progressively worsen following damage/tear/puncture? No 4.6 Can the defence height of the product be increased during service? No 4.7 Resistance to damage (a) Wind Fixation to the ground in the front and extra available "wind-prevent" to the back allows the Aqua Fence to withstand storms of 9 Beaufort or more A Strap attached at a built-in eye-bolt (M10) on the upper end of the elements and down to the back by fixing it to a further eye that is connected to a 12 mm bolt into the ground. One prevent each element is sufficient. It will withstand wind like Beaufort 9 from behind, and it is possible to add this function when needed even after installation.

5 (b) Waves Aqua Fence behaves very well in inland-water, even in wild-water and can withstand waves. This has been confirmed in the certification process - TU Hamburg-Harburg, can withstand waves up to 0.5m. (c) Inertia forces None, water stabilizes the system and 0.2m of flood water makes the additional fixation obsolete. (d) Overtopping (including maximum depth without failure if known) System is fixed, so overtopping is not a problem (e) Floating debris A front fixing shield can be added to prevent impact from debris, e.g. logs of greater than 1 ton (f) Water pressure As the elements are filled with water and have a rigid frame they are resistant pressure water pressure. 4.8 Repair during service conditions Yes. For bigger damage, a board plate with gaskets or very thick soft cell rubber material for sliding in should be used at the waterside inside the elements. The water will in this case squeeze the patch towards the

6 element, holding it in place and seal the leakage. They will further be supp0rted with wood screws from outside. Furthermore it is possible to build bypass-solutions:

7 5. OPERATIONAL ASPECTS 5.1 Time required for installation (100 m long х 1 m high) We recommend a team of 10 persons (or less) to assembly 100 m, and 8 to 10 persons will assemble 100 meter in 1 hour. 5.2 Method of installation (including site preparation) Manual Installation is by man-power, however battery drills are preferable. 5.3 Likelihood of incorrect installation The design is prepared to prevent incorrect assembly. It is self-explaining and the "Step-by-Step" guide will easily instruct the workers how to install this properly. 5.4 Storage requirements We recommend storing the elements on pallets within container or warehouse. The elements can stand both very high and low temperature. The main material is wood, thus it should be not stored for too long in direct sunlight. It does not need to be absolutely dry, but animals (mice and rats) and vermin might be a threat. 5.5 Are storage solutions supplied with/available for the product e.g. containers/ racking systems/ trailers. One 40 ft container can transport /store 18 pallets. 2 pallets can be placed on top of each other during transport or storage.

8 5.6 Transportation requirements (including mobilisation) Can be transported on pallets in containers, trucks, boats or planes. 5.7 Access requirements Each element can be transported by hand, but also by front-loader, lorry, quad or else. AquaFence has developed carrier handles. 5.8 Adaptability to terrain conditions (Surface type) Any Surface Flat Soil Grassed Surface Sloping Surface 2.5m Wide Banktop 4.0m Wide Banktop Wall Concrete Other (*) (*) A mobile solution with an extra gasket is available to put up AquaFence on limited sloping surface, or e.g. cobblestones. 5.9 Provision of fixings / Susceptibility to damage or vandalism Relatively secure; although most parts that can be stolen or disconnected are located in or under water. Canvas can be easily repaired even under operation if it is damaged by vandalism Possible locations of use Banks - Fluvial watercourse flood bank/levee Banks - Up to 400mm waves Banks - Reservoir banks Banks - Up to 400mm waves As second line defences (away from watercourse) Enclosures (around property/properties) Access locations (permanent breaks in defences (not breaches)) Other 6. FINANCIAL ASPECTS 6.1 Installation resource requirements For 1000 m. we recommend 3-4 teams of 6-8 persons. All installation can be done by man power after the system has been delivered to site (by e.g. truck, ATV or lorry etc) It is recommended to use battery powered drills for faster tightening of the wheels and bolts. 6.2 Installation costs (100 m long х 1 m high excluding resources) 475/m ( 550/m prices) with all elements included. If foundation is required, pre-fabricated concrete elements with fastening rails are available for 8/m. 6.3 Additional installation and removal costs (training/supervision) Yes, if requested. 6.4 Maintenance requirements Elements must be rinsed and checked for any damage. Replace any damaged components or repair the plywood if damages to the wood. Inspection should be around once a year. 6.5 Ease of cleaning (often use in muddy conditions) Rinse with clean water after use. 6.6 Reuse of the products Yes, when properly maintained and stored, Aqua Fence can be re-used for approx years.

9 6.7 Product covered by manufacturer s warranty. (Length, type and limitation of warranty) Standard EU-warranty of 1 year 6.8 Deterioration with time Only when damaged. If stored to manufacturers specification then the system will not deteriorate significantly. 7. OTHERS 7.1 Product trial or test information Aqua Fence has received the BWK and FM-Global certificate - October Currently no certification for BSI Kitemark (PAS ) has been undertaken, however, the tests undertaken for the BWK and FM-Global certificate by Prof. Pasche from Technical University Hamburg also included the standards and requirements of BSI Kitemark (PAS ) in their test procedures. 7.2 Awarded (BSI) Kitemark for Temporary and Demountable Flood protection products (PAS :2003) No 7.3 Performance under service conditions/ In use The Aqua Fence has been demonstrated to withstand actively flowing water when anchored to the ground surface. 7.4 New products or modifications under development. Yes, will be specified at a later point of time 7.5 Environmental qualities No toxic waste is absorbed in the elements and plywood used by Aqua Fence is certified and comes from cultivated forestry. 7.6 Environmental Impact No environmental Impact, the system is completely removable after the event leaving no permanent damage to the deployment site. 7.7 Details of clients or locations where product is in service Mount Vernon, Seattle US.
