Cofferdams are temporary enclosures built within a body of water so the water can be pumped out of an enclosed area. They’re essential for creating a dry working environment so building and repair crews can excavate riverbeds and build or repair underwater structures along rivers, lakes, and other waterways.
Traditionally, these structures are quite expensive and challenging to build. However, there are solutions that allow crews to work safely in watery environments.
TrapBag barriers can be installed at a fraction of the cost of conventional steel sheet pile walls. They also take much less time to install and can even be installed directly in the water up to certain depths.
Setting up TrapBag as a temporary cofferdam is as easy as three simple steps:
With proper dredging and other preparations, workers can use cellular cofferdams to complete construction projects in shallow water. Cellular cofferdams are interconnected cells within the body of water where the water has been dredged or otherwise removed.
These can be used for installing bridge piers and footings, locks, dams, and other in-water structures and machinery.
Where cellular cofferdams are primarily used for underwater construction, these are used to support walls on excavation projects, or otherwise hold water back from excavation sites.
Each cofferdam variety has advantages and disadvantages. The project location, budget, and site limitations should be considered before installing a specific type of cofferdam.
The typical cofferdam cost can easily soar into the tens of thousands of dollars for traditional structures. Even more, they can easily deteriorate with repeated use, especially in the presence of saltwater.
However, TrapBag is a more affordable solution that has been trusted for everything from riverbank stabilization to storm surge protection for years. It’s as good at keeping water in as it is at keeping water out, making it ideal for construction and engineering projects where water can cause problems and setbacks.
Public works departments and other government agencies can utilize TrapBag to create working environments in aquatic or flood-prone areas of all kinds. Whether it’s for emergency bridge maintenance and repair or larger city planning projects, TrapBag cofferdams create a safe, watertight setting for agency workers to get the job done.
Building and demolition companies can use a cofferdam for bridge construction and other projects that require working in areas that are normally covered in water. They’re also less expensive to purchase and build than traditional sheet pile structures, making them an ideal solution for keeping projects on shallower creeks and riverbeds within scope.
We work with civil engineering firms, emergency management organizations, mining companies, and everyone in between to protect the projects and places that matter most. Whether you need a way to stabilize riverbanks or contain stormwater to prevent it from entering the drinking water supply, TrapBag can protect life and property from all sorts of construction and natural damage. It’s also a great solution for security barriers, stormwater detention and retention, temporary seawall systems, and much more.
Whether you live in an area prone to flooding, river stabilization, erosion control, or anything in between, TrapBag can protect life and property from all sorts of natural disasters and damage. It’s also a great solution for security barriers, stormwater detention and retention, cofferdam systems, and much more.
