Temporary Water Filled Barriers

A cofferdam is a temporary enclosure in or around a body of water that is constructed to allow dewatering, diversion or damming of an enclosed area. The coffer dam is filled with water to create a barrier, and emptied once it is no longer necessary. Using a water filled barrier offers the advantage o

 

Water Filled Barriers for Water Control

Today’s temporary water filled barriers are primarily used to hold back flood waters or to provide a dry environment for a project to proceed. Examples of temporary water barriers are cofferdams (also coffer dams) and sandbags. There also are permanent water barriers that include dams, levees, locks and seawalls.

Temporary Water Filled Barrier Applications

There are many applications for temporary water barriers, especially cofferdams. One company – Dam-It Dams, Inc. – offers patented, portable, water-filled Cofferdams that provide effective and cost-efficient solutions for these major types of situations that they call the 3-Ds of water control:

Dewatering

De-watering, unwatering and water control are common terms used to describe the removal or drainage of ground or surface water, typically on a construction site. This technique is often required before subsurface excavation for such things as foundations, shoring, cellar space and repairs to existing water structures.

Examples of Dewatering water-control situations include:

  • Boat ramp repairs
  • Bridge repairs
  • Dredging
  • Environmental remediation
  • Shoreline restoration
  • Wetland protection

Diversion

Diversion is the temporary (or sometimes permanent) re-routing of water. It may be required to initiate a project and/or allow a project to proceed.

Examples of Diversion water-control situations include:

  • Bridge repairs
  • Dredging
  • Environmental remediation
  • Flood control
  • River crossings
  • River flow
  • Spillways
  • Wetland protection

Damming

Damming is the process of creating a barrier that holds back water. The barrier may be needed to maintain water table levels, collect water for storage and prevent water from crossing established/safety thresholds.

Examples of Damming water-control situations include:

  • Bridge repairs
  • Canals
  • Cold weather projects
  • Dredging
  • Environmental protection
  • Environmental remediation
  • Flood control
  • Flood protection
  • Shoreline protection
  • Shoreline restoration
  • Spillways
  • Wetland protection

Why Our Cofferdams Are Preferred for use as a temporary water barrier

There are two primary reasons our cofferdams are preferred by contractors worldwide:

  • Dam-It Dams’ Cofferdams work with Mother Nature, not against her, and therefore create effective water barriers that leave no – or only a minimal – footprint on the environment
  • Our cofferdams are industrial strength and reusable, thus, minimize additional investment costs.

Finally, our cofferdams are immediately available in a wide range of sizes to accommodate virtually every project manager’s needs. Contact us today for more information and a free quote. Click here damitdams.com to go to our Home Page.
