PIPELINE INSTALLATION & REPAIRPipeline repair or replacement projects can be complex, particularly when water is present. We understand that pipeline repairs often require completion in a short time frame. Aqua-Barriers™ provide the fastest cofferdam method available. The next time that you are confronted with a temporary cofferdam need, let us save you time and money.

Aqua-Barrier™ Water Inflated Dam Product Specification

1.1 Specification A water-inflated temporary dam shall consist of the following: 1) The water inflated dam will consist of a self contained, single tube with an

inner restraint baffle(s)/diaphragm(s) stabilization system. The water-inflated dam must have the ability to stand alone, without any additional external mechanical or gravitational stabilization devices, as a positive water barrier and water management system.

2) The water-inflated dam shall be produced from heavy gauge polyvinyl chloride (PVC) reinforced

with polyester. The PVC fabric used to create the inflatable dam will be infield repairable utilizing a vinyl adhesive and patch material.

3) The water-inflated dam must maintain mechanical stability in addition to providing anti rolling when exposed to uneven hydrostatic pressure from either side

4) The self-contained water inflated dam shall have threaded fill ports and drain ports for rapid inflation and draining. The dam will be equipped with end lifting loops used to control the dam with equipment during the installation and removal process.

5) Method for connecting the individual units together will consist of overlapping the end of the units a specific length which will create a watertight connection. No other devices or methods for connecting the barriers are required.

1.2 Aqua-Barrier™ Product Description Aqua-Barriers™ are water-inflated dams used to control invasive water in floodwater situations, a means of water management to provide access to underwater areas for construction and maintenance operations, hazardous liquid containment, sediment retention in environmentally sensitive areas in addition to a continually expanding list of water control related applications. Aqua-Barriers™ are a single tube devise with a patented inner restraint baffle(s)/diaphragm(s) stabilizing system required for stability. 1.3 Dam size requirements The water-inflated temporary dam height shall be determined as follows: 1) Static water height conditions shall not exceed 75% of the properly filled height of the barrier. 2) Dynamic water height conditions shall not exceed stated value during hydrodynamic installation

procedures (See dynamic installation instructions for complete list of requirements). 3) Installation site criteria are required for assessment of all relevant factors. Excess slope, high water velocities, dynamic loads resulting from wave actions, mounting surface irregularities, and changes in interrelated hydrological conditions can increase the required water inflated dam height verses retention height requirements.

AQUA-BARRIER FEATURES AND BENEFITS

PATENTED BAFFLE SYSTEM:

The Aqua-Barrier utilizes a patented fixed internal baffle system which insures a

safe and stable system. When the Aqua-Barrier is exposed to uneven hydrostatic

pressure, the internal baffle system locks into place. The Aqua-Barriers’ system

provides stability & safety.

USER FRIENDLY:

Aqua-Barriers have a unique lifting loop on each end which enables a track hoe

arm to control the barrier while installing and removing. This allows for

minimal manual labor during the installation & removal process.

ENVIRONMENTALLY FRIENDLY:

Aqua-Barriers are installed using the available water source at the jobsite with

minimal adverse impact to the environment. Post job restoration is not needed

using Aqua-Barriers. Simple drain and remove the barriers from the water with

little or no turbidity.

LARGE SCALE JOBS:

Multiple Aqua-Barriers can be connected together to cover large areas. The

Aqua-Barriers are connected to one another by utilizing a simple overlapping

procedure that requires no additional time during the installation and no

potentially hazardous underwater work

SAVE TIME AND MONEY:

Aqua-Barriers install in less time than most conventional cofferdam methods.

Approximately 500 linear feet of Aqua-Barriers can be installed in 1 day using 6

men, 2 track hoes and 2 water pumps

DURABILITY:

Aqua-Barriers are made with a scrim reinforced PVC material and industrial

grade fittings and intended to be reused numerous times. The Aqua-Barrier

system is infield repairable in wet or dry conditions utilizing a repair kit which

is provided with each order.
