3. Unique Features of the Tiger Dam System
The system has been designed to be rugged, stable and adaptable to a wide variety of
situations and climates
Tiger Dam is comprised of a series of engineered interlocking tubes that when filled
with water form a temporary dam, or with concrete to create a more formidable
structure.
Can be configured in any shape, any length from a few feet in length to miles and from
and can be stacked to 32ft in height.
Tiger Dams are modular and simple to use (like lego blocks). They can be custom
made to any height or diameter to meet the specific need of the project. The
components are easily connected and can be stacked. This avoids wasting valuable
time and resources keeping Louisiana’s communities and precious coastline intact.
4. Design Features Continued
Speed is a critical component in building a containment barrier so
the system was designed to be deployed rapidly. Depending on
the method of filling, each standard tube (19inches x 50 feet) can
be filled in as little as 3 minutes.
Each Standard Dam weighs only 65lbs.(empty), can be handled
by one or two men thus eliminating the need for heavy equipment.
When full of water weighs 6300 lbs, while the concrete filled dams
weigh 14,000 lbs to help ensure dam stability.
After each deployment the equipment is simply drained, cleaned
and rolled up for future use. The Concrete dams can be picked up
and moved to another location, or recycled for future concrete use.
With proper care the reusable system (tube/dam) is designed to
last up to 17 years or longer if not left in the sun… (its maximum
UV rating).
Dams can be repaired with a customized adhesive patch system
specifically designed to adhere to our material.
5. Engineering
The system has been independently assessed for function and safety by a
leading certified engineering laboratory.( Engineer Report is attached)
Research and development was conducted at the University of British Columbia’s
Ocean Engineering Test Center .(BC Oceanic institute)
Test results showed that the system exceeded its design criteria and preformed
well under a wide variety of situations.
6. Engineering
Is stable when subjected to wave action.
Burst test demonstrated a maximum internal pressure of
17 pounds per square inch. The system typically operates
at 2 pounds per square inch.
Puncture tests met or exceed all applicable ISO standards.
The fabric is a heavy 28 ounce Vinyl coated polyester
coated with vinyl in a propriety fashion. The fabric is
resistant to a wide range of chemicals and is UV stable.
The valves are 2 inch check valves with a bayonet style
connector.
The connecting straps are 2 inch polyester with a ten
thousand pound tensile strength.
The anchors are 26” long and can support 4500 lbs each.
Recommended number is dependant upon specifications
of each project.

9. Environmental Impact
By using the Tiger Dam systems we can minimize the impact on the surrounding
areas, therefore improving the overall benefits of the project.
Both the Tiger Dam and the concrete Tiger Dam are environmentally friendly.
The water system will utilize water directly from project area site. When the
project is complete the water can be pumped out, allowing the dams to be moved
to another locations and reused.
The concrete Tiger Dam are filled with a flow able recycled concrete. Upon project
completion, should the dams need to be removed, they can be cut into sections
and lifted away, redistributed to another job site in tact or taken to be broken down
and recycled again.
