Construction Projects and Dewatering Precautions

Dewatering is needed on nearly all construction sites. Water needs to be removed from these sites to create a safer work environment, help prevent erosion, and also help protect the environment. It is important to consider some dewatering precautions before getting started on a project. Here are a few to remember:

  • Water should never be pumped directly into slopes.
  • Discontinue dewatering if the area shows signs of instability or erosion.
  • Channels used for dewatering need to be steady and protected by grass and vegetation.
  • Never dewater during heavy rains. The water and infiltration rate will be slower during the dewatering process or it will not function entirely.
  • Never discharge water that contains oil, grease, or chemical products.
  • Make sure to acquire any additional permits from state, local, or federal agencies.

Dewatering Methods

There are many dewatering methods to get the dry worksite you need for your construction project. These vary from open excavation, trenches, gravity drainage channels, and also inflatable cofferdams. An Aqua-Barrier® Inflatable Water Dam is the perfect tool for many dewatering and construction projects and is a more environmentally friendly and safe alternative to other traditional dewatering methods.

ProTip: An Aqua-Barrier® Cofferdam is the perfect alternative to sheet piling and sandbags that is environmentally friendly, as well as cost and time effective.

Ensure Safety with Dewatering Precautions

Whether you are working on a bridge repair, pipeline construction, sediment control, or shoreline restorations, keeping your work site safe requires dewatering and following the dewatering precautions above.

Shoreline Stabilization Techniques for Managing Erosion

Shoreline Stabilization Techniques for Managing Erosion

Our shorelines are very important, providing habitats for fish and wildlife, and cleans stormwater runoff before it gets to the water supply. Shoreline erosion is a natural process which takes place on all bodies of water, such as lakes, streams, oceans, and rivers. When erosion becomes too much, it can harm the water quality, ecosystem, and even cause property loss. When this happens, shoreline restoration techniques need to be implemented to help halt the erosion of the natural shoreline.

Shoreline Stabilization Techniques

To preserve shoreline protection and natural resources, erosion control becomes necessary. Shoreline erosion can progress too rapidly. Here are the best ways to stabilize the shoreline and help slow down the rate of erosion. Click To Tweet

  1. Imitate Nature
  2. Bulkheads & Retaining Walls
  3. Buffer Zones
  4. Erosion Matting
  5. Stone & Vegetative Rip Rap

1) Imitate Nature

In its natural state, the shoreline is able to perfectly protect itself against erosion. Imitating nature is the perfect way to help prevent erosion. Use native vegetation around the shoreline to help build structural integrity and prevent the land from breaking apart. The deep roots of these plants help protect the land from heavy rainfall and winds.

2) Bulkheads & Retaining Walls

Bulkheads and retaining walls have been used with the intention of preventing erosion, but it has been found that these methods end up increasing erosion eventually. From an environmental standpoint, retaining walls are the most expensive and the most environmentally harmful option there is. If you have a retaining wall or bulkhead currently set up, it would be wise to remove it and work on a more natural shoreline stabilization method.

3) Buffer Zones

Buffer zones have been found to be effective in slowing down shoreline erosion. A buffer zone is a stip of vegetation at the water’s edge that typically extends between 50 and 100 feet. Native vegetation should start returning to this area, or you can supplement grass and native species with deep roots and woody vegetation to help speed up the process.

4) Erosion Matting

With the advances in technology, there are now biodegradable products on the market to help get control of exposed shorelines. Erosion control matting is a three-dimensional geotextile fabric that is laid down on the shoreline. Spread a layer of seeds under the mat, then once the matting is laid down, spread ¾ an inch of soil on top and then spread seeds over the mat, as well.

5) Stone & Vegetation Rip Rap

This particular method of shoreline stabilization should only be used if other, more natural methods have not worked. This technique needs a stable underlying soil base and can be difficult to put in place. The basic idea is to lay the rip rap (hard quarry stones, or a combination of live vegetation and stones) in two layers. This technique allows for the shoreline to be stabilized while still providing some habitat for wildlife.

Restoring Shoreline Erosion

As you see, there are numerous options for helping prevent shoreline erosion. When it comes time to performing restoration techniques, be sure you are using the best tools for the job. An Aqua-Barrier® Inflatable Cofferdam will allow you to create a temporary dam in order to get a dry workspace to begin the shoreline stabilization projects, without having to worry about flooding surrounding areas.

Pro Tip: Shoreline stabilization projects that call for dewatering can cause flooding to surrounding areas. Mitigate the risks with an Aqua-Barrier® Inflatable Cofferdam.

The Fascinating History of Cofferdams

The Fascinating History of Cofferdams

Cofferdams are used in many industries when dewatering and water diversion are necessary. You might not realize it, but the history of cofferdams is long and fascinating and dates back thousands of years. During this time the cofferdam has evolved and improved several times.

The Evolution of the Cofferdam

Cofferdams have been around for centuries, but they haven’t all looked or worked the same. The history of cofferdams is interesting and takes us back to the Persian empire. Here is the timeline of cofferdams used throughout history and how they have advanced through the years.

  1. Earthen Cofferdam
  2. Roman Cofferdam
  3. Sandbags
  4. Steel Sheet Pile Cofferdam
  5. Aqua-Barrier® Inflatable Cofferdam

1) Earthen Cofferdams

The first cofferdams were said to be used by King Cyrus of Persia in 539 B.C. to temporarily divert water from the Euphrates river, allowing the capture of Babylon. This capture of Babylon ended their rule, allowing the Medo-Persian empire to begin.

2) Roman Cofferdams

The Romans had their own cofferdam, as well, and it was made from wood pilings that they temporarily used in order to build bridges across the Danube river in 102 A. D. in what is now Romania.

3) Sandbags

In the 1880’s, during the Napoleonic wars, people used sandbags to control water. Initially, these bags of sand were used for the protection of the troops during battle, but eventually, they were used as temporary dams and water control.

4) Steel Sheet Pile Cofferdams

After a hundred years of using sandbags, a milestone in cofferdams was introduced through the steel sheet pile cofferdam. In the early 1900’s, a German engineer came up with an interlocking design of ‘U’ shaped steel to help control water. This interlocking steel cofferdam design is still being used today in some countries.

Top Tips For Construction Water Diversion

Top Tips For Construction Water Diversion

While a dry worksite is essential for many construction and repair projects, there are some cases where it is not feasible to completely cut off the water flow.  Sometimes, a project requires you to completely block off the water for the duration of your project, while others need a diversion to keep the water flowing smoothly while you work. Having the proper tools and plans will help your construction water diversion project be completed in a safe and timely manner. Click To Tweet Here are some helpful tips for successful water diversion on your next project.

Diverting Water for Construction Projects

Often, construction projects require work done across streams, rivers, or similar small bodies of water. Since these bodies of water cannot be fully blocked, water must be diverted to maintain a healthy flow. Some typical projects requiring water diversion are:

About Water Diversion

Sometimes a diversion is necessary for construction to ensure an isolated, dry project area. In some cases, water is temporarily rerouted in order to prevent or minimize contamination of clean surface waters. Water diversion also provides an effective method of sediment control. With water diversion, work zone sediment is prevented from entering the body of water, which is especially crucial when dewatering stormwater areas.

Best Method for Water Diversion

Working in water is one of the most complex construction scenarios imaginable, and an Aqua-Barrier® Cofferdam should be an essential component of your water diversion project. Easily deployed and completely portable, Aqua-Barrier® can be used in a variety of configurations to divert water, creating a dry work environment.
