Why is it Called a Cofferdam

The use of cofferdams has been around for centuries. With time, it has continued to improve and advance throughout the years.  A cofferdam is a physical structure used in a body of water. It allows the contractors to dry out the work area; enabling them to perform “in water” construction projects in a dry and safe environment.

Cofferdams were first used for protection during battle and later used as a temporary dams for water control. In the early 1900’s a milestone in cofferdams was introduced in the form of steel sheet pile invented by an engineer in Germany. Larssen’s “U” shaped piling with its interlocking design is still used today.

There are various types of cofferdams. They include:

  • Cantilever Sheet Pile Cofferdam
  • Braced Cofferdam
  • Earth Embankment Cofferdam
  • Rock Fill Cofferdam
  • Double Wall Cofferdam
  • Cellular Cofferdam

These cofferdams serve as temporary barriers in and around bodies of water. They are built to hold back floodwaters and create a dry environment for a project to proceed.

What is a Cofferdam Used For

A cofferdam is a kind of watertight enclosure built within a body of water. It facilitates construction projects and allow the enclosed area to be pumped out. This pumping creates a dry work environment so that the work can be carried out safely and effectively. Cofferdams are commonly used for the construction of piers and other types of structures within bodies of water. They are usually formed from sheet piles that are supported by internal braces. Usually once the construction project is completed, the cofferdam is then dismantled.

A cofferdam can be made of many types of materials as well as shapes. The most common shapes include circular cofferdams and rectangular ones. However the most important thing is to have a cofferdam that is structured for stability.  The structure and material of a cofferdam will directly impact how reliable it is in holding water back. The cofferdam must be able to withstand high pressures in order to provide safety for the workers on-site. Cofferdam walls can reach all the way to the surface of the water, with an opening at the top or it can be totally enclosed. I deeper waters, enclosed ones are safer while open structures tend to work best in shallow water.

Fender Marine Construction has the experience and knowledge needed to build strong, safe and secure cofferdams for your next marine construction.

What is a Cofferdam Toe

A cofferdam is a temporary enclosure designed to keep out water and soil as to allow dewatering and construction of a permanent facility or structure on dry land. It involved the interaction of the structure, soil and water. Removal of the cofferdam must be planned with precision and executed with the same degree of care as its installation. During cofferdam construction, safety is a vital concern since workers will be exposed to the dangers and hazards of flooding and structure collapse. 

There are many advantages of a cofferdam. Performing work on water has always been difficult and more costly than performing work on dry land. Below are some of the advantages of cofferdams:

  • Allow for excavation and construction of structures on dry land.
  • Provides a safe environment for contractors
  • Sheet piles are easily installed and removed.
  • Materials can usually be used on other projects.

Every cofferdam is unique and requires precision and attention to detail. The design must be compatible with the weather conditions, waves, currents, construction equipment, etc.

Types of Cofferdams

Working in and around water poses a lot of challenges for crews. Cofferdams are constructed and installed with one purpose: to retain water and provide a dry surface for crews to successfully and safely build projects. There are many different types of cofferdams. There are ways to customize a cofferdam depending on the job site. Cofferdams vary in size and material.

Below are some types of cofferdams:

  • Braced Cofferdams - Braced cofferdams are made from a single wall of sheet piles driven into the ground. This is what forms a box around the excavation. Beams are then braced in order to stop them from collapsing inward. This is where the name “braced” comes from. The cofferdam is then de-watered. This cofferdam design will withstand strong waters and give workers the chance to work around the area.
  • Cellular Cofferdams - Cellular cofferdams tend to be the best option for larger projects. This type of cofferdam is designed to support large work areas. These are made by driving sheet piles into a circular pattern and then repeating the process next to the original in order to form circular sections The circular cells connect thus providing a tight seal against the water.
  • Double Walled Sheet Pile Cofferdams - These cofferdams are made of two parallel rows of sheet piles driven into the ground and connected together by a system of tie rods or more levels. The space between the walls in then filled with sand, broken rock and gravel.
